Description
Loctite NS 5550 is a premium brown gasket sealant formulated for sealing metal components exposed to extreme heat. Its thermally reactive chemistry allows it to cure rapidly and form a strong, reliable seal that resists breakdown under high operating temperatures.
Designed primarily for metal-to-metal applications, Loctite NS 5550 is widely used in industrial assemblies, furnaces, exhaust systems, and heavy machinery where conventional sealants fail. The paste consistency enables uniform application, while the brush-top packaging ensures precise coverage on flanges, joints, and mating surfaces.
This gasket sealant is particularly effective in environments requiring resistance to heat cycling, vibration, and thermal expansion, making it a trusted choice for maintenance, repair, and overhaul (MRO) operations.
