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.
