Claims19
An apparatus comprising:
- a body with a first end and a second end, the second end having an annular protrusion extending therefrom;
- an adapter having an axial groove with an outward edge, the axial groove being dimensioned so that the outward edge contacts the annular protrusion of the body while the body is coupled to the adapter, wherein the outward edge and the annular protrusion are deformed when the body is coupled to the adapter;
- a seal ring disposed within the axial groove;
- and
- a tensioner to couple the body to the adapter.
