Permabond® LH150 Pipe Sealant with PTFE is designed for sealing and locking tapered metal pipe threads and fittings. It is ideal for stainless steel and other passive metals. Instant sealing of up to 1000 psi is achieved upon limited hand tightening. After cure, the sealing capability is up to the burst rating on the typical pipe. The low locking strength allows easy disassembly.
UL Classification:
Permabond LH150 is classified by Underwriters Laboratories Inc. ® for use in devices handling gasoline, petroleum oils, and natural gas (pressure not over 100 psig) propane and butane not exceeding 2 in. 66G9.
