For the mechanical fitting shown, we removed 1-1/2 in. You can quickly distinguish between the light beige color of CPVC pipe and the bright white of PVC. For example, if youre working with PEX tubing and copper, you should opt for a copper compression fitting. This will allow you to tighten the nut and pull the end of the pipe tightly against the internal O-ring. 1. Spread the cement lightly on the inside of the fitting and a bit heavier on the pipe. Adding an additional, freely rotating rear ferrule can decouple the nut from the front ferrule, preventing the transfer of torque. Pop up drain emitter problems: Main Reasons And Effective Solutions. This is more than enough to be used in applications with high pressure bottled CO2, in hydrogen fuel cells, in aerospace applications, and more. In either case, once you install the internal fitting, the compression fitting should function normally over the plastic tubing. Here, the joint will never be under pressure. (Consult the manufacturer for an MSDS technical data sheet.) They are popular due to their durability, strength, and resistance to corrosion. Therefore, you want to use nylon or PVC. Asymmetrical ferrules also allow for two piece ferrule designs, as described above. Refrigerators and other coolant lines normally arent strong enough for brass compression tubing, even with an insert. Hold the fitting against the pipe, and slide the compression ring up against the fitting. Start with the nut and put it on one side of the tubing.

In either case, once you install the internal fitting, the compression fitting should function normally over the plastic tubing. 2. How To Install A Compression Fitting On Plastic Tubing? Chief among these are fitting and ferrule design, tubing selection, and installation procedure. Just hand-tighten the nuts on all fittings of this type. Lubricate the end of the pipe with dishwashing liquid. Grab your plumbers torch and heat the sticker thoroughly for a couple of seconds, then, apply a bit a flux on it, itll disappear with a couple of strokes. It is this radial compression that creates the leak tight seal between the fitting, ferrule, and tubing, and gives the compression fitting its name. This stiffener may be as simple as a similarly sized internal pipe. If you can't get a leak to stop, you may have cross-threaded the compression nut, or the compression ring may not be seated properly against the fitting. After that, get your adjustable wrench and tighten the nut once more. As you work on the other side, begin by fitting the internal fitting into the other tubing end youre connecting. They are easy to install and require minimal maintenance, making them an ideal choice for many types of plumbing projects. Insert the Pipe into the Fitting. Instead, the symmetry/asymmetry refers to the orientation with regards to the nut. Such small leaks usually stop in a day or two. Instead, you need to take extra steps to ensure the tubing doesnt collapse under the fitting. Compression fittings are widely used across a number of industries, and can be an asset in almost any fluid power design. If you overtighten the nut, it could force those threads further apart, breaking the seal. Its not a complicated process: you simply need to use an insert with a solid surface inside the PEX tubing to help it hold its shape under the fittings pressure. Disassembly involves simply loosening the compression nut or screw. The functioning principle of each component also remains more or less the same between designs: tubing is inserted into the end of the fitting, and the nut/screw is tightened, forcing the ferrule(s) into the fitting body. Watch carefully for leaks, keeping an eye on the fitting in particular. The black acetal copolymer also resists ultra-violet ray attack and has excellent dimensional stability. Tighten the compression nut by hand. Insert the Internal Fitting and If you do however have a kink in your pipe, cut it a couple of inches before or else you run the chance of having a leaky joint. Any sealant as needed by your inserts. The next step is to tighten the nut (be sure its backed off at least one or two turns from tight before you push the tubing into the connector). Make sure its tightly in place. Turn off the water supply, then cut your pipes where youd like to tie in. Key factors include: pressure and temperature extremes, environmental conditions, vibration conditions, fluid compatibility, and minimum bend radius. If you ever need to remove the fitting, you simply loosen the nut, slide back the nut and ring, and pull the pipe and fitting apart. Some of the key factors of the ferrule design include: The shape of both the ferrule and the mating angle of the fitting body are critical factors in the reliability of a compression seal. Start by slipping your compression nut over your pipe. Besides the 1/4 inch compression fitting plastic tubing, you In most cases, its a good idea to match materials in mixed materials.

The ease of assembly and disassembly is one of the reasons why compression fittings are so widely used. Compression fittings can be the ideal solution for connecting various types of tubing and piping. Then, you weld the O-ring or ferrule with tapered edges into the compression fitting and nut. The trick to a leak-free installation is making sure the pipe end is cut square and is smooth and clean. Compression fittings use a nut, a plastic compression ring, and a seal to create a tight seal on any pipe. Once the fitting is secure, its ready to use. Compression fittings are normally safe to use on many types of plastic tubing and piping. Thats because a brass fitting may not fully fit over a PVC. Leave a gap, as shown in Photo 8, especially in a long run. There are many reasons to install a compression fitting rather than a screw fitting or solder. Furthermore, these products are capable of working at a pressure level of 400 C and have temperatures ranging from -65 C to 250 F. Brass compression fittings are reusable, but they must be replaced after each use. The cold flow issue is exacerbated when the tubing is exposed to high temperatures, and can occur even when fittings are properly installed and initially leak free. Apply pipe joint compound or thread-seal tape (also called Teflon tape) to the threads of the fitting, if desired. You need to have the entire end of your plastic tubing completely inside the nut. Following fittings installation instructions, first, turn off the water supply. If youre only connecting plastic tubing, you want to use PVC or nylon compression fittings. Its also less expensive than copper. One factor to plan for in these high purity applications is galling. Theyre a safe alternative to soldered fittings in various situations, making them a popular pick. If youve ever done any soldering, you know that you have to get rid of all the water in the adjacent copper pipes to heat the pipe to accept the solder. Fit the compression fitting onto the pipe (or fit the pipe into the fitting, as applicable) until the pipe stops inside the fitting. Use your finger to pull out any debris from inside the pipe. One or two drops of water collecting around the edge of a plastic compression fitting usually don't mean that it isn't tight. Hey! They provide an effective way to connect two objects together, securely and reliably. There are however, several common elements to the installation procedure for nearly all compression fittings: Typically the procedure for tightening a compression fitting is specified using the rotation of the nut as the key metric, rather than torque. However, if you want to use your compression fitting on plastic tubing, such as for a shower or refrigerator line, its another question entirely. It's durable too.

Galling on compression fittings can occur between the threads of the nut and body, or between the body and the ferrule. Brass sleeves are a type of component used in many industrial and manufacturing settings. The use of softer tubing (such as polyurethane or vinyl) is not normally recommended with compression style fittings because the tubing wall is likely to collapse, or move away from the ferrule. Required fields are marked *. You can also use a stab-in tee to connect PEX fittings supply to CPVC. Compression fittings are a perfect choice in these situations. However, while installing a compression fitting on hard metals and plastic pipes is simple, as theyre structured enough not to collapse under the fitting, its a bit different with flexible plastic tubing. All components work together to create a watertight seal. For more information, visit brasscraft.com. Compression fittings create removable plumbing connections on standard rigid and flexible copper pipe and tubing. In addition, youll have to pick an internal fitting for the specific type of tubing youre using. Next, apply the CPVC cement to the tubing and the inside of the fitting. To secure it firmly, tighten the fitting with a wrench. The tubing insert, usually made of metal, is pressed into the soft tubing, and supports the tubing wall so that it will not collapse as the ferrule is compressed. Do not use a wrench. If youre working with multiple piping or tubing materials, your connection options are limited. Make sure the room is well ventilated. Too many whiffs of this stuff is bad news. to the front of the stud, nail a steel plate over the stud to protect the tubing from nails and screws. E.g., buy PEX fittings for PEX tubing.

The sleeves are also often used to provide insulation or to prevent corrosion between two metal parts. Check the compression fitting for leaks after you've completed all of the other plumbing connections and turned on the water supply to the pipe. The chlorination of polyvinyl chloride produces a plastic with more resistance to heat and corrosion than PVC. Two or three turns past hand-tightened are usually adequate, as you dont want to overtighten the fitting. Rotate the cutter once or twice in the reverse direction. Miniature compression fittings are found in applications ranging from chromatography and bomb detection instruments, to medical devices and inkjet printing. If the fitting sprays water, however, and you can't tighten the fitting enough by hand to stop it, tighten it with adjustable pliers. Compression fittings come in many configurations, including elbow fittings and tees. The same rule applies to the internal fitting, so use the same concept. Heres a list. Contact your local plumbing inspector to see if CPVC is permitted in your area. In Leave at least 1/2-in.

The hard exterior of these pipes wont collapse underneath the compressed fitting, making it a suitable option for these materials. Separate each piece of the fitting, including the nut, ferrule, body, and stiffener, setting each piece within reach. There are also compression union fittings that join two pipes in a straight line. This type of cutter is designed to produce straight, burr-free cuts on CPVC and PVC tubing. To ensure that the fitting is properly seated, what I like to do is tighten it ever so slightly, then hit the back of the fitting to ensure its seated properly, as opposed to hitting it without tightening it, it would bounce back and not seat properly. Keep in mind that a crooked cut will have less surface area to cement and a greater chance to leak. Avoid over-tightening or you could strip the threads. 740. However, that may not be necessary. These grip-style fittings are much easier to install in situations where pipe condensation would make soldering a real chore. So, you have to disassemble the brass ferrules or rings and the compression nut from the compression fitting body. Next, screw the compression fitting onto the tube. The joint gets most of its strength from the slight taper on the inside of each fitting, so a reasonably straight cut is necessary for a good fit. Only a small amount is required for it to do its job. Compression fittings are ingenious because you can use them in places where welding isnt an option. However, you should use an insert to support the tubing. Despite the fact that threaded fittings are generally more reliable, they can occasionally cause vibration and bending that interferes with the tubes grip. Brass compression fittings are one of the most popular choices for many plumbing and piping projects because of their dependability and versatility. Additionally, the relative angles of the ferrule and the fitting body will determine how much linear motion is converted into radial compression, and what level of contact (line contact or surface contact) is made with the tubing. Compression fittings are most commonly used with hard tubing because the tubing wall must be rigid enough to resist the compression forces applied by the ferrule. Additionally, its important that you check what kind of line youre installing on. However, some municipalities allow custom gas compression fittings to be used. Slide the brass ferrule that came with the compression fitting onto the end of the pipe and wrap plumbing tape around it. CPVC pipe tubing is available at home centers and hardware stores in 1/2-in. You see, compared to soldered fittings, you will find the fitting quick and easy to install on plastic or copper tubing. Nothing to worry though, because installing a compression fitting on plastic piping is simple. Tighten the cutter so the cutting wheel is snug against the However, you cant slap a compression fitting on the end of PEX tubing and call it good. For example, PEX tubing is sized differently than refrigerator lines. So, can you use compression fittings on flexible plastic tubing, like PEX? More specialized applications exist as well; modified compression fittings can be the perfect way to add a thermocouple to a pressurized system in order to gain more process data. and 3/4-in. This is then bent and squeezed tightly against the tapered surface of the fitting as a nut on the pipe is tightened. Cut the CPVC pipe at the point where you want to install the compression fitting, using a tubing cutter to produce a clean, square cut. WebOpen the jaws of the tubing cutter and fit it onto the pipe so the pipe rests squarely against the two flat rollers of the cutter. This increases the ease of assembly in applications where many fittings are used, and assembly time is critical. Start by inserting the internal fitting into the tube. Therefore, you should never use compression fittings on your gas lines. PEX Expansion Vs Crimp: Whats The Actual Difference? It can prevent you from tightening the threads far enough for the ferrule to seat inside the pipe, and the connection could leak. Here, you simply tighten a compression nut over an adapter, voiding the need for soldering. While an elastomeric seal can deform to match these slight variations, the metal-to-metal seal of a compression fitting is less forgiving. You can also cut CPVC pipe with a chop saw. In stainless steels, rotation of the ferrule can also produce galling and cause permanent leaks. Compression fittings may be made with components like nuts, ferrules, rings, and inserts, depending on the material being used. Why Have Natural Remedies Become So Fashionable Again? Once the pipe and fitting are together, you slide the ring against the fitting, then thread the nut onto the fitting. Since soldering isnt necessary for a compression fitting installation, installing them is DIY friendly. Hunker may earn compensation through affiliate links in this story.
