PIPE CONNECTOR SYSTEMS, DEVICES AND METHODS

摘要

Systems, devices and methods for pipe connectors and associated components are disclosed. Features for no hub clamps, for locking mechanisms on no hub clamps, for tools for no hub clamps, and for gaskets are described. The clamp has a band with a locking mechanism for convenient locking together of the ends of the band about two adjacent pipes. The locking mechanism may include a securement feature such as a tab on one end of the band and a complementary engagement area on the other end. The band may have arcuate gripping projections whereby rotation of a tool head causes linear translation of the two ends of the band. The various locking mechanisms may be tightened and secured using various tools having engagement features complementary to the gripping projections. The gaskets may be hourglass-shaped to facilitate assembly onto pipe ends with longitudinal membrane sections that collapse when a clamp is secured over the gasket.

主权项

1. A gasket comprising:
a rounded sidewall defining a channel therethrough in a first direction, the sidewall comprising a top end and a bottom end opposite the top end, the top and bottom ends each comprising:
a first sidewall portion having a first edge and a second edge that is opposite the first edge with an inner seal extending generally perpendicular to the first direction and at least partially between the first and second edges along an inner surface of the first sidewall portion, the first and second edges extending generally in the first direction, and the first sidewall portion having a first thickness; anda first membrane section connecting the first edge to the second edge, the first membrane section extending generally in the first direction, and the first membrane section having a second thickness,wherein the second thickness is less than the first thickness.
