Abstract
Fittings configured as quick-connect couplings or valve assemblies utilize an O-ring to lock a male member within a female member. The O-ring engages a shoulder to both effect a seal and to prevent axial motion of the male member with respect to the female member. In accordance with one embodiment of this invention, pressure within lines coupled by the quick-connect couplings is used to effect locking of the couplings and in accordance with another embodiment, pressure within a container with which the valve assembly is used effects locking of the coupling.
