AR250 is a fast-curing, high-strength, anaerobic adhesive for locking and sealing threads and retaining of cylindrical parts. This formula allows larger machining tolerances and is recommended for slip fit applications. AR250 is highly resistant to heat, corrosion, vibrations, water, gases, oils, hydrocarbons, and many chemicals.


  • MULTI-USE: Best for retaining shafts, gears, pulleys, and cylindrical parts
