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.

A valve fitting, comprising:
- an adaptor comprising a supply end and a receiving end, the receiving end comprising an exterior surface and an internal sealing surface;
- a valve assembly comprising an insert end;
- the insert end comprising a sealing surface;
- and
- a connector, wherein:
- during a rough plumbing installation of the adaptor, the connector engages a test cap assembly inserted into the receiving end, the test cap assembly including a test cap and an o-ring, the test cap having a wall extending on a longitudinal axis to a sealed end, the longitudinal axis being perpendicular to the sealed end, the wall protecting the internal sealing surface of the receiving end of the adaptor by forming a seal against the internal sealing surface of the receiving end of the adaptor, the sealed end including an annular ring on an outer surface and the connector including an internal shoulder of an engagement end engaging the annular ring of the test cap assembly to hold the test cap assembly within the receiving end;
- and
- during a finish plumbing installation following a removal of the test cap assembly from the receiving end of the adaptor of the rough plumbing installation, the sealing surface of the insert end of the valve assembly seals against the internal sealing surface of the receiving end of the adaptor in a sealing engagement, the connector engaged to the valve assembly and an exterior of the adaptor, the connector forming 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, the internal shoulder of the engagement end engaging a retaining ring circumscribing the insert end of the valve assembly to retain the connector to the valve assembly.
