Vibra-TITE 137 High Temp-High Strength Threadlocker is a red single component anaerobic threadlocker. 137 joins threaded parts exposed to operating temperatures up to 450 degree F. It offers excellent performance at temperatures more the 150 degree higher than other threaded locking products because of its enhanced chemistry. Applications include high temperature locking and sealing of studs, nuts, screws, bolts, and fittings. Parts are locked and sealed against leakage, contamination and corrosion. The higher viscosity is more suitable for large diameter, coarse threaded parts. It is recommended for parts that do not require routine maintenance as disassembly is difficult and may require heat. Ensure parts are clean, dry and free from oil and grease before use. Product is normally hand applied from the bottle onto threaded parts. Fixture Speed with Primer is
