Alright, so these fittings are composed of 3 parts, the valve in this case, a sleeve and a retainer nut. Compression fittings are a perfect choice in these situations. This negates the holding power of the ferrule, and can also prevent the ferrule from making a leak-tight seal around the full diameter of the tubing. Make sure the room is well ventilated. Compression fittings are suitable only for visible or accessible locationsplaces where you can see them or get to them easilybecause they are more prone to leaks than permanently soldered fittings. In many applications, high pressures and temperatures necessitate the use of hard tubing, which is incompatible with many other types of fittings. Start by inserting the internal fitting into the tube. Scrape away any burrs from the copper pipe and rub a drop of dishwashing liquid on each end of the copper to act as a lubricant. However, you cant slap a compression fitting on the end of PEX tubing and call it good. In most cases, you can even reuse your compression fitting. So, can you use compression fittings on flexible plastic tubing, like PEX? How Much Does Lowes Charge To Install A Garbage Disposal? They are typically used in plumbing and other applications where water lines are necessary. Harsh water won't harm the material, unlike copper, which will erode from acidic water. This system is designed to be very user-friendly, and because the outside diameter of CPVC tubing is sized the same as copper pipe, the grip-style mechanical fittings (Photos 3 and 4) can be used on both copper and CPVC pipe. Spread the cement lightly on the inside of the fitting and a bit heavier on the pipe. Then, slide your tubing into the compression body, tighten the nut with your hand, and lastly, use a wrench.
