IMPA: 812749

Anaerobic Pipe Thread Sealant – Medium Strength (IMPA 812749)

This medium strength anaerobic pipe thread sealant is designed for marine and industrial applications where a reliable, leak-proof seal is essential. It cures in the absence of air between tight-threaded metal surfaces, creating a tough, solvent-resistant film that withstands vibration and high pressure. Perfect for sealing joints in hydraulic, pneumatic, fuel, and lubrication systems.

Formulated to seal metal pipe threads instantly, this thread sealant resists fuels, oils, coolants, and hydraulic fluids. It is ideal for use on stainless steel, steel, brass, and aluminum fittings. The product conforms to IMPA code 812749, making it a standard ship chandler supply item for onboard maintenance and repair operations.

Frequently Asked Questions

What is the curing time for this pipe thread sealant?

This anaerobic sealant sets in 15 minutes at room temperature and reaches full mechanical strength after 24 hours.

Can this sealant be used on stainless steel and brass fittings?

Yes, it is compatible with most metal pipe and fitting materials, including steel, stainless steel, brass, copper, and aluminum.

Is the sealant resistant to fuels and hydraulic fluids found on ships?

Absolutely. It resists gasoline, diesel, oil, hydraulic fluids, coolants, and even natural gas, making it ideal for marine applications.

Can pipes sealed with this product be disassembled later?

Because it is a medium-strength sealant, disassembly is possible with standard hand tools. If extra torque is needed, heating the joint to approximately 230°C will break the bond.
