A compressible end-fitting for a welding gun liner includes a tubular body. A head is disposed at an end of the tubular body. The head is wider in diameter than the tubular body. A sleeve is disposed around the end portion of the tubular body that includes the head. The sleeve includes a stepped inner surface defining a shoulder. At least one biasing member is disposed between the head and the shoulder. The biasing member(s) urges the head outwardly away from the sleeve. An annular stop on an outer surface of the tubular body is contactable with an edge of the sleeve to limit movement of the head relative to the sleeve. The head is linearly retractable from a resting position into the sleeve by application of an axial force, and the biasing member(s) returns the head to the resting position when the axial force is removed. |
