Blue Monster industrial-grade thread sealing compounds are now available in convenient, 2-oz. squeeze tubes that are ideal for any tool box or storage bin. Two formulas are available with and without PTFE to seal threads on all metals, PVC, CPVC, ABS and nylon plastic pipe systems. Blue Monster industrial-grade thread sealant is specially formulated with superb sticking characteristics. The compound with PTFE is specially formulated for extra lubrication on pipe threads. Both formulas feature a slow-drying, soft-setting and non-hardening compound designed to improve sealing of threaded pipe systems, especially when poor-quality threads are an issue. Both formulas are lead-free, nontoxic and will not harden or separate in the tube.
