Loctite DATAC245501 is a 50ml tube of Loctite 518 red anaerobic gasket sealant. This medium-strength sealant is specifically engineered for sealing rigid iron, aluminum, and steel flanged mating surfaces, commonly found in transmission housings and engine casings. It cures effectively in the absence of air when confined between close-fitting metal surfaces. The sealant provides excellent resistance to oils, water, glycols, and transmission fluids, ensuring a durable and reliable seal. It is designed to fill gaps up to 0.25 mm and maintains performance across a wide temperature range from -55°C to +150°C, offering resistance to vibrations and shocks.
