  • Publication number: 20100066075
    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.

  • Publication number: 20090057601
    Abstract: The present invention provides an integrated valve, push connection and push release components, and a valve mounting assembly for use on fluid, air or gas applications. The invention allows for the installation of the valve by sliding the valve over the supply tube/piping or pushing the tube/piping into the valve. Once connected, an o-ring seals the connection, a packing gland applies energy to the o-ring seal maintaining constant, even pressure across the seal, and a grip ring applies opposing energy to prevent the disconnection of the assembly. The quick connection assembly is retained by a retaining cap, which applies constant, positive force on the sealing surface.
