Abstract: A pipe sealing gasket is shown which is designed to be received within a groove provided within a socket end of a thermoplastic pipe. The gasket has a ring shaped body of an elastomeric material and includes a metal reinforcing band. The metal reinforcing band has an angular profile, when viewed in cross-section, with an apex which is embedded within the gasket body but lies in close proximity to an exterior surface of the gasket. The apex provides a reinforced contact point during belling operations but is isolated from surrounding liquids passing through a pipe joint.
