LOCTITE^® 272 is a red, medium viscosity, high strength, anaerobic-curing, threadlocking adhesive with high temperature resistance. It is specially designed for the permanent locking and sealing of threaded fasteners and to withstand temperatures up to 232°C (450°F). The anaerobic adhesive cures when confined in the absence of air between close fitting metal surfaces, and prevents loosening and leakage from shock and vibration. Ideal for the locking and sealing of large bolts and studs.
