A push fit connector system utilizes a locking sleeve which is inserted within an internal tapered section of a cylindrical housing. A pipe end inserted into the cylindrical housing is received within the locking sleeve. Withdrawal of the pipe from the cylindrical housing is prevented as the locking sleeve radially collapses as it is received within a smaller diameter of the internal tapered section.

The present invention relates to a novel locking hose clamp device. The device is designed to function as a locking nut and remain tight. The device comprises a lock washer and an insert component. The device can be applied to a clamp and secured with a screw. The insert component is positioned around the screw, such that the screw is threaded into the insert component. The locking washer is secured around the screw, behind the head of the screw. When the user tightens the device, the screw threads catch onto corresponding threads within the insert component. The screw is threaded into the insert component and tightened down, such that the head of the screw contacts an edge of the insert component. The locking washer is then compressed which causes the screw to lock in place.

The present invention relates generally to a kit for coupling a first pipe to a second pipe. The kit includes an elastomeric coupling sleeve provided with top and bottom ends sized to snugly fit within the respective first and second pipes. The coupling sleeve includes top, intermediate and bottom portions and an inner surface that defines a passageway. A first passageway portion extends between the top and intermediate portions and a second passageway portion extends between the intermediate and bottom portions. The first passageway portion tapers toward the intermediate portion and has threading formed along the inner surface. The second passageway portion tapers toward the intermediate portion and has threading formed along the inner surface. The kit also includes top and bottom rigid expansion rings that have threading formed along their outer surfaces configured for engagement with the threading formed along the inner surface of the first and second passageway portions, respectively. When operatively connecting the coupling sleeve to the first and second pipes, each expansion ring is threadingly engageable with the associated portion of the coupling sleeve so as to urge the coupling sleeve in the region of the expansion ring to bulge outwardly and seal the coupling sleeve against the respective first and second pipe.

A method of using a mechanical joint restraint includes inserting an end of a pipe length into a gland bore of a gland, a ring bore of a gripping ring, and a gasket bore of a gasket, the gland, the gripping ring, and the gasket together forming the mechanical joint restraint; inserting at least a portion of the gasket of the mechanical joint restraint into a socket of a piping element; inserting the end of the pipe length into the socket of the piping element; and drawing the gland towards a flange of the piping element to compress the gasket into sealing engagement with the piping element and the pipe length.
