ABSTRACT:
A tube coupling includes a coupling body having a throughway open at one end to receive an end portion of a tube, an annular step in the throughway facing the open end to provide an end stop for a tube end, and an end cap engaging the coupling body for axial movement between forward and retracted positions on the body. The end cap has an opening for the end portion of the tube to extend therethrough and a tube locking collet in the cap to permit entry of a tube into the cap and to resist withdrawal. An annular seal is located in the coupling body adjacent the annular step, the seal having an inner annular portion with which the tube end is engageable and an outer annular portion, and a sleeve between the locking device and seal to compress the outer annular portion of the seal axially.
