Abstract
An adapter for joining a sprinkler to a pipe element has a body with outer flat surfaces and grooves that receive seals. A plug for sealing a pipe element has a cylindrical body with a circumferential groove which receives seals. Both the adapter and the plug fit within the pipe element and are 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.
