Loctite 55 is a high-performance, multi-filament thread sealing cord designed for sealing threaded metal and plastic pipe fittings. It provides an instant, reliable seal without curing time, making it ideal for plumbing, industrial, HVAC, pneumatic, hydraulic, and gas piping applications. Unlike traditional PTFE tape or hemp, Loctite 55 allows fittings to be adjusted after assembly while maintaining a leak-proof seal.
The sealing cord is easy to apply by wrapping it around the male threads before assembly. Once tightened, it fills the gaps between threads to create a durable seal that resists vibration, pressure, temperature fluctuations, and corrosion. This helps prevent leaks while reducing installation time and maintenance requirements.
Loctite 55 is suitable for use with hot and cold water, drinking water systems, natural gas, compressed air, and many industrial fluids. It is compatible with a wide range of threaded pipe materials, including steel, stainless steel, brass, copper, and most engineering plastics.
