Compressed gas pipe thread sealant is a leak proof sealant for high pressure threaded pipe joints. It is a thick white liquid that seals compressed gas pipe or fittings threads to prevent leaks. It is brushed onto pipe threads before assembly to help prevent leaks. It fills thread imperfections or gaps and then cures into a tough elastic solid. It is ideal for use in vacuum systems, valve threads, natural gas, compressed air lines, refrigeration systems and bottled welding gases.
