Loctite LC230410 Flange Sealant 510 is a high-temperature resistant, anaerobic gasketing product designed for rigid metal flange sealing. This genuine Loctite sealant provides excellent oil resistance and can fill gaps up to 0.25 mm. It cures when confined in the absence of air between close-fitting metal surfaces, forming a flexible, solvent-resistant seal that will not tear or creep. Ideal for applications requiring high temperature and chemical resistance, ensuring reliable sealing of pumps, gearboxes, and engine components.
