Abstract
Plumbing fitting assemblies are described. The plumbing fitting assemblies use a male and female fitting combination that enables a user or installer to make a sealed connection on an internal diameter of a female part or receiving end by way of an o-ringed shank on a male part or insert end. A connecting device is rotatably attached to the male end. The connecting device also engages to an outer surface of the female part such that the sealed fitting assemblies will not disconnect under normal pressure of a fluid or air working through the assemblies.
Claims28
A valve fitting, comprising:
- an adaptor, the adaptor comprising a supply end and a receiving end, the receiving end comprising an exterior surface and an internal sealing surface;
- a valve assembly, the valve assembly comprising an insert end;
- the insert end comprising a sealing surface;
- the insert end of the valve assembly inserts into the receiving end of the adaptor, and the sealing surface of the insert end seals against the internal sealing surface of the receiving end of the adaptor in a sealing engagement;
- and,
- a connecting device engaged to the valve assembly, wherein the connecting device engages to an exterior of the adaptor to hold the internal sealing surface of the receiving end of the adaptor and the sealing surface of the insert end of the valve assembly together in the sealing engagement.

A valve fitting, comprising:
- a male part, the male part comprising a shank, wherein the shank comprise one or more o-rings positioned about an exterior the shank;
- a female part, the female part comprising an internal sealing surface and an outer engaging surface;
- the internal sealing surface of the female part receives the shank of the male part in a sealing engagement;
- and,
- a connecting device rotatably attached to the male part;
- the connecting device engages the outer engaging surface of the female part to hold the male part and the female part together to maintain the sealing engagement.
3 more elements
A valve fitting, comprising:
- an adaptor, the adaptor comprising a supply end and a receiving end, the receiving end comprising a threaded external diameter and an internal sealing surface;
- a valve assembly, the valve assembly comprising an insert end;
- the insert end comprising a sealing surface;
- the insert end of the valve assembly inserts into the receiving end of the adaptor to form a sealing engagement between the internal sealing surface of the receiving end of the adaptor and the sealing surface of the insert end of the valve assembly;
- a nut rotatably engaged to the to the valve assembly, the nut comprising a threaded internal diameter;
- and,
- the threaded internal diameter of the nut threadably engages to the threaded external diameter of the receiving end of the adaptor to maintain the sealing engagement between the internal sealing surface of the receiving end of the adaptor and the sealing surface of the valve assembly.
