<p>A self-contained cartridge sealing plug that does not require any torque settings. The sealing plug includes a cylindrical-shaped plug body that carries an 0-ring seal. The bottom of the plug body has a hole where a spring is inserted and retained by a spring retainer that locates the spring and/or functions as a backstop for the spring that preloads the plug body against a retaining member. The spring-loaded action allows the plug body to be inserted into a -non-threaded cavity and depressed past a groove in the cavity. Once the shoulder on the plug body passes the groove, a wire ring retainer including one or more arcuate segments can be inserted into the cavity. The spring energy is then released against the ring retainer, retaining the plug body in the cavity.</p> |
