A hybrid push-to-connect fitting, comprising:
- a fitting body member having an interior wall, an exterior wall and an axially outer rim, wherein the interior wall defines an internal cavity extending through the fitting along an internal axis;
- at least one packing arrangement comprising a release pusher maintained within the internal cavity of the fitting body member, wherein the release pusher comprises a wall having inner and outer surfaces, with at least one cavity formed in the wall;
- a nut connector threadably securable to the exterior wall of the fitting, with the nut connector having a radially extending end wall;
- and
- a single body shoe member secured between the axially outer rim of the fitting body member and the nut connector radially extending end wall, wherein the single body shoe member comprises a split body having exterior and interior surfaces, and further comprises at least one notch extending radially inwardly from the body interior surface, wherein the single body shoe member is compressible between the fitting body member and the nut connector so that the at least one notch extends into the at least one cavity formed in the wall of the release pusher.
