Abstract: An improved valve fitting configured to limit pressure exerted upon a surface of the valve by a sealing surface of the fitting to inhibit the sealing surface from deforming causing the valve to leak is provided. This causes the sealing surface of the fitting to exert a constant pressure upon a sealing surface of a valve body, when the fitting is coupled to the valve body, to form a continuous seal between the fitting and the valve, to inhibit leaks therebetween. When the fitting is coupled to the valve body, the compression member is compressed to limit the pressure that the sealing surface exerts on the valve body, to inhibit the sealing surface from distorting, or deforming, against internal componentry of the valve which can form gaps between the sealing surface and componentry, causing the valve to leak.

A locking ring is accommodated in and rotates around the central axis of the female half of the device and is provided with radially inward-projecting locking segments rotated by an outward-extending lever around a prescribed angle out of an assembly position and into a locking position. Stops on the male half in the form of several radially outward-projecting locking cams are distributed at prescribed angles and separated by gaps at least as wide along the circumference as the locking segments. The gaps between the locking segments are at least as wide along the circumference as the locking cams.

Abstract: A fast pipe joint is composed of a sleeve and a main body. The sleeve is fitted over the main body such that an elastic piece extending upward from lower end of the inner edge of the sleeve is engaged with a retaining hole of the main body.
