  There are various ways pp compression fitting are used. tHE pp compression fitting is required in both plumbing and electrical conduit systems to join pipework or tubing together. They are also used in toilet stop valves and hot and cold water taps in domestic and industrial settings. As well as being used in the construction industry, compression couplings are common in oil and gas, biotech, and chemical industries.

  Generally, a compression fitting consists of an inner ring and outer nut, made either of brass and copper. The inner ring is known as a ferrule. This fitted over pipes to be joined and the outer nut slipped over it. The piping is then clamped together by tightening the nut so it presses against the ring creating a tight fitting that should be air tight and water tight seal. When larger compression fittings are required, there is usually a flange, rather than a single nut, with a ring of bolts each of which must be tightened evenly to ensure a proper and effective seal. In all cases, the nut should not be too loose or over tightened as this can compromise the fitting and cause leakage.

  To install tubing into a pp compression fitting, you must simply insert the tubing through the collet and O-ring, and into the body of the fitting. The only trick is to make sure you have inserted the tubing all the way into the fitting. If you have not pushed your tubing past the O-ring on the inside of the fitting, you will experience a leak because the O-ring is not sealing properly. One way to be sure that your tubing has been inserted all the way is to mark the end of it at about the three-quarter inch line. When you press the two pieces together, the three-quarter inch line should disappear into the fitting.
