ABSTRACT:
A pipe fitting assembly package and fastening ring removal tool allow re-use and repair of push-fit piping fittings and valves without damage to the fitting or valve elements or the pipe. The quick connection pipe fitting assembly package of the present invention employs a threaded retaining cap that when removed, exposes the clamping, sealing and fastening mechanism of the fitting or valve. In one embodiment, the present invention further includes a removable packing gland mounted on a body about an axis of an orifice. The fastening ring removal device provided as part of the present invention is manually pushed onto the cylindrical object and is capable of expanding to traverse over the installed fastening ring. The fastening ring removal device includes a parallel angular surface to lift the fastening ring off of the pipe member. In one embodiment of the present invention, the removal device has a plurality of cut areas or slits extending axially along its surface to allow for the expansion of the upper rim portion of the fastener removal tool as it slides over a remaining fastening ring. The present invention facilitates re-use of existing fittings and valves by allowing the internal components to be removed, repaired and/or replaced.
