Thread Compounds

Thread compounds is a generic name used to refer to a large category of sealants, retainers, and lockers that are used on casing, tubing, line pipes, and all types of cylindrical parts, including bearings, bushings, gears, and much more. Thread compounds fill the gaps in threading, provide gas and liquid leakage resistance, prevent binding and thus increase the total joint reliability. Thread compounds are available as pastes, gels, and tapes.

Among the most commonly used thread compounds are threadlockers - liquid polymer substances applied to the threads of various fasteners before they are installed. As the polymer dries, it locks the fastener securely in place, inhibits rusting and prevents loosening, unwanted movement, and leakage. According to their holding power, the threadlockers are divided into heavy-duty, medium-grade and light-duty compounds. Holding power estimated in PSI determines the force applied to "unlock" the threadlocker. Heavy-duty threadlockers are used to assemble engine parts, can withstand extreme temperatures and are rated for up to 3000 PSI.

Thread sealants help create strong connections between threaded pipes and fittings. They fill the space between the threaded metal elements resulting in a reliable seal that prevents leakages caused by loosening, solvent evaporation, damaged threads, extreme pressures, and temperature cycling. Thread sealants also feature outstanding lubricating properties that allow for easier assembly and help to prevent galling. There is a range of thread sealants suited for professional and casual, high and low pressure applications. Available as tape, spreadable paste, or sticks, thread sealants seal instantly without clogging the pipes, valves, and filters.

Thread retainers and retaining compounds are high-strength anaerobic adhesives designed to retain shafts, bushings, bearings, oil seals, gears, pulleys, and other similar cylindrical parts. Retaining compounds will significantly increase joint reliability by curing and forming a strong precision assembly. When cured, the adhesive is a tough thermoset plastic that can withstand prolonged exposure to a variety of solvents and engine fluids as well as extreme temperatures. These products help achieve maximum load transmission capability and uniform stress distribution. Retaining compounds can add up to 3000 PSI of holding power.
