Pipe cap

In a preferred embodiment, there is provided a pipe coupling comprising a coupling body having two or more open ends and a pipe engagement assembly for attachment to the open end for engagement of a pipe thereto, the pipe engagement assembly comprising a retainer ring and a grip ring, and the coupling body comprising a sidewall defining an internal bore sized for receiving at least a portion of the pipe and the retainer ring, the retainer ring being dimensioned to be received at least partially by the grip ring and to receive the pipe therethrough, wherein the grip ring comprises a plurality of first projections extending inwardly towards the bore to engage the pipe, and the retainer ring comprises one or more second projections extending outwardly to releasably engage the sidewall, the retainer ring defining a plurality of slots sized to receive the first projections therethrough, wherein the slots are positioned to retain the first projections with the grip ring engaging the pipe and the second projections engaging the sidewall, thereby retaining the grip ring and the pipe to the open end.

Push-fit pipe fitting

A connection to releasably connect and disconnect to a pipe to a fitting provides a pipe fitting body for receiving a pipe and a retaining ring assembly located within the fitting body for retaining and releasing the pipe. The retaining ring assembly has axially extending inwardly angled resilient retaining tabs, each of which has a pipe retaining portion. When the pipe is inserted into the fitting body to an inserted position, the pipe retaining portions engage an indentation on the pipe to retain the pipe in the inserted position. Relative movement of the axially extending inwardly angled resilient retaining tabs with respect to the fitting body from the first locked position to a second unlocked position causes each axially extending inwardly angled resilient retaining tabs to disengage from the indentation on the pipe permitting removal of the pipe from the inserted position in the fitting body.

Releasable connect/disconnect fitting connection

A first firestop device and a second firestop device, each comprising a housing. The housing of the first firestop device has a connection side with a plurality of connection elements and the housing of the second firestop device has a complementary side with a complementary element. The connection elements are each arranged at a different location on the connection side of the housing of the first firestop device, so that a position of the first firestop device relative to the second firestop device, when the connection side of the housing of the first firestop device is interlocked with the complementary side of the housing of the second firestop device, is selectable by selecting which of the connection elements of the first firestop device is connected to the complementary element of the second firestop device.

Cast in place device

A connection to releasably connect and disconnect to a pipe to a fitting provides a pipe fitting body for receiving a pipe and a retaining ring located within the fitting body for retaining and releasing the pipe. The retaining ring has axially extending resilient retaining tabs, each of which has a radially inwardly extending portion for engaging the pipe, and, a radially outwardly extending portion which extends through corresponding radial openings in the fitting body. When the pipe is inserted into the fitting body to an inserted position and the retaining ring is in the first locked axial position, the radially inwardly extending portions engage and retain the pipe in the inserted position. Relative axial movement of the retaining ring with respect to the fitting body from the first locked axial position to a second unlocked axial position causes the radially outwardly extending portions to operatively engage the corresponding body radial openings to resiliently radially outwardly deform each resilient retaining tab thereby disengaging the radially inwardly extending portions from the pipe and permitting removal of the pipe from the inserted position.
