Compression Valve End Connections

Compression Valve End Connections. This type of valve end has a socket to receive the pipe and is fitted with a screwed union nut. The joint is made by the compression of a ring or sleeve on to the outside of a plain-end pipe, or by compressing a preformed portion of the pipe end. As a rule compression ends are used with copper tubing and steel tubing up to 65mm diameter and are used for low pressures or where pipes may require frequent dismantling.
