The Test-Tite Pressure Relief Pneumatic Test Plug is a patent-pending device designed for the purpose of testing or temporary blocking of plumbing DWV systems. Manufactured with a patent-pending pressure relief valve that is integrated into a glass-filled nylon core for protection and extra rigidity in the field. The internal pressure relief device acts as a safety valve to reduce the chances of over inflation. The Pressure Relief Test Plug is designed to release excess pressure above the suggested inflation pressure, into the atmosphere rather than into the test area, thus reducing the possibility of over inflation or blowouts.
Features
Pressure relief automatically resets for each inflation
Pressure relief has no moving parts to fail or malfunction
Pressure relief exhausts out of the top of the plug not into test area
Molded as one-piece with no seams or bonded parts
Works in place of standard pneumatic plugs
Internal pressure relief device releases pressure when plug exceeds maximum pressure levels
5 sealing ribs in the center portion of the plug for positive sealing
