Harmonization Code : 3506.10.00.00 | Prepared glues and other prepared adhesives, not elsewhere specified or included; products suitable for use as glues or adhesives, put up for retail sale as glues or adhesives, not exceeding a net weight of 1 kg
Main features
- Up to 1000 psi Instant Air Seal
- PTFE Non-Shredding Pipe-Dope Alternative
- UL Gas/Fuel/Sprinkler Classification
Product Description
Permabond® LH050 is a general-purpose, PTFE-filled anaerobic pipe sealant that cures to form a solid plastic seal when confined between threaded metal parts. Formulated as a smooth white paste, it immediately provides an air pressure seal up to 1000 psi with only limited hand tightening, and upon full cure, its sealing capability matches the burst rating of the pipe itself. Its low locking strength facilitates easy disassembly, making it an excellent, non-shredding alternative to traditional pipe dopes and PTFE tapes.
Key features
- Instant seal capability: Delivers an immediate air pressure seal up to 1000 psi upon application, prior to full cure.
- UL Classified: Classified by Underwriters Laboratories (UL) for use in systems handling gasoline, petroleum oils, natural gas, propane, and butane, as well as sprinkler and water spray systems.
- Reliable & Clean: 100% solid, solvent-free formulation that will not shred, tear, or cause blockages in fine filters or valves like traditional PTFE tape can.
Applications / Suitable for
- Sealing threaded metallic pipe joints, plugs, and fittings (particularly steel and brass)
- Systems requiring UL classification for handling fuels, oils, or gases
- Assemblies requiring an instant pressure seal and easy subsequent disassembly
