Abstract

A seal assembly is configured for use at PVCO pipe junctions. The seal assembly includes a main seal body made of a monolithic resilient material, such as rubber, and a stiffener. The seal has a stiffener pocket sized and configured to accept the stiffener, such that the stiffener can be assembled to the seal body by hand. This assembly can then be installed into the bell end of a first PVCO pipe, and a spigot end of a second PVCO pipe may then be inserted into the bell end and engaged with a main sealing lobe of the seal assembly. The seal assembly is configured to reliably withstand the insertion process, without damage or degradation to the sealing structures. Once installed, the seal assembly provides a robust fluid-tight seal along all potential leak paths between the seal assembly and the first and second pipes.
