LOCTITE 510 is a high temperature resistant anaerobic sealant which is used for making and dressing gaskets in rigid assemblies. Typical applications include sealing rigid flange faces on transmissions and motor casings. It ensures an instant, low-pressure seal. The product increases the torque capacity of assembled flanges.

Loctite 515 is a medium strength (6 N/mm² tensile shear strength), medium cure speed, methacrylate-based industrial gasketing product designed for machined, rigid metal flanges. The product, which cures anaerobically, is suitable for gaps up to 0.25 mm. It is used typically as a form-in-place product for pumps, thermostats, compressors, transmission housings and axle covers.

LOCTITE 518 is designed for use on rigid iron, aluminum, and steel flanged mating surfaces. Fills gaps up to 0.25mm and forms a flexible, chemical-resistant seal that will not tear or decay. Typical applications include sealing close fittings on transmissions, motor housings etc.
