LOCTITE threadlockers dramatically increase the reliability of threaded assemblies. Available as liquid and semi-solid adhesives, LOCTITE threadlockers are applied to the threads of a fastener and cure to a hard thermoset plastic when applied between metal surfaces. They cure in the absence of air and completely fill the gaps between mating threads to lock and seal threads and Joints.

Thread Sealing

LOCTITE anaerobic thread sealants prevent leakage of gases and liquids and are available in liquid form or as sealing cord. Designed for low pressure and high pressure applications, they fill the space between threaded parts and provide an instant, low pressure seal. When fully cured, they seal to the burst strength of most pipe systems.

LOCTITE gasketing products are self-forming gaskets that provide a perfect seal between components, with maximum face-toface contact, eliminating flange face corrosion. They form a low-pressure seal immediately on assembly and fully cure in 24 hours, providing a joint that will not shrink, crack or relax. They are available as anaerobic products for rigid flanges and Silicone products for flexible flanges.

LOCTITE anaerobic retaining compounds secure bearings, bushings and cylindrical parts into housings or onto shafts. They achieve maximum load transmission capability and uniform stress distribution and eliminate fretting corrosion. Applied as a liquid, they form a 100% contact between mating metal surfaces, eliminating the need for expensive replacement parts, time consuming machining or the use of mechanical methods.
