Markal Leak-Tite Blue thread sealant is ideal for sealing water, air, steam, natural gas, refrigerants, gasoline, and ammonia. It is also ideal for use on production lines and fabrication shops. Leak-Tite Blue is non-toxic and contains PTFE particles for greater sealing power. Leak-Tite Blue will not harden or dry out over time, but remains flexible for easy disassembly, and it washes off hands and clothes easily for quick cleanup.
