LOCTITE® 243™ is a medium-strength, blue threadlocker designed for locking and sealing threaded fasteners. It cures in the absence of air between close-fitting metal surfaces, preventing loosening and leakage due to vibration or shock. It provides reliable performance on both active metals (e.g., brass, copper) and passive substrates (e.g., stainless steel, plated surfaces). The product is oil-tolerant and suitable for use on fasteners in pumps, gearboxes, motors, and vehicles.
