Product Name
Permabond Anaerobic LH150 Pipe Sealant Anaerobic Adhesive
Brief Description
Permabond LH150 is a fast-curing, general-purpose anaerobic pipe sealant with PTFE, designed for sealing and locking tapered metal pipe threads and fittings. It provides an instant seal and, once fully cured at room temperature, offers maximum sealing capabilities up to the burst rating of the pipe. This adhesive replaces traditional pipe dopes and tapes, providing excellent chemical and temperature resistance.
Popular Applications & Uses
- Sealing and locking tapered metal pipe threads and fittings- Replacing pipe dopes and pipe tapes- Sealing connections in hydraulic, pneumatic, lubrication, steam, and refrigerant systems- Use in devices handling gasoline, petroleum oils, natural gas, propane, and butane- General pipe maintenance- Fire protection systems- HVAC systems- Plumbing systems- Sealing hairline weld fractures
Industries that Commonly Use It
- Automotive Service/Repair- Chemical Industry- Construction/Building Services- Energy (including natural gas, petroleum, propane, butane)- Engineering Services- General Manufacturing- Government & Military (due to UL classification for specific applications)- Industrial Supply- Metal Fabrication- Petroleum Industry, Products or Services- Pool/Spa/Plumbing- Transportation/Specialty Vehicle (automotive, heavy machinery)
Special and Unique Features
- Full cure seal to the burst rating of the pipe- Easy to use and apply- Directional freedom for pipe alignment- Does not contain solvents- Will not shred, tear, or cause blockages- Low locking strength allows for easy disassembly- Instant sealing up to 1000 psi upon limited hand tightening- UL Classified for use in devices handling gasoline, petroleum oils, and natural gas (pressure not over 100 psig) propane and butane not exceeding 2 inches 66G9- Accelerated curing properties, especially on steel and certain plated fittings- Low shrinkage during cure- Uncured material fully dissolves in water- Nonflammable

Comparison Note
Permabond LH150 offers a faster cure rate compared to Permabond LH050. It provides superior sealing capabilities and resistance to vibration, corrosion, seizing, and galling compared to traditional pipe dopes and tapes. Unlike some other anaerobic adhesives, LH150 has a low locking strength allowing for easy disassembly, which is beneficial for maintenance. Its UL classification for specific fuel and gas applications highlights its suitability for regulated environments.
