Abstract

A plug for sealing a pipe element has a cylindrical body with a circumferential groove which receives seals. The plug fits within the pipe element and is secured and sealed by a deformation formed in the pipe element by a circumferential groove. The deformation mechanically engages the grooves in the body of the adapter and the plug.

First claim

What is claimed is:

1. In combination, a pipe element and a plug, said plug comprising:
a body having a cylindrical outer surface;
a circumferential groove extending around said outer surface;
a shoulder extending outwardly from said outer surface, said shoulder being positioned in spaced relation away from said groove;
at least a first seal positioned within said groove and contacting said body;
at least a second seal overlying said first seal; wherein
said first seal comprises a resilient material and said second seal comprises a compliant material; and
said pipe element comprises:
a sidewall defining a pipe bore, a portion of said body including said groove being received within said pipe bore;
a deformation positioned in said sidewall and extending circumferentially there around, said deformation being aligned with and extending into said groove and contacting said second seal and thereby sealingly retaining said body within said pipe bore, and plugging said pipe element.

2. The plug according to claim 1 , wherein said second seal is selected from the group consisting of polyester, a silicone adhesive, an acrylic adhesive and an expanding gel seal.

3. The plug according to claim 1 , further comprising a cavity positioned within said body.

4. The plug according to claim 3 , wherein said shoulder is positioned at an end of said body, said cavity extending into said body from said end.
