Loctite thread sealants, available as liquid or fibre sealants, prevent the leakage of gases and liquids. Designed for both high and low pressure applications, they fill the gap between the threaded parts, creating an instant seal at low pressure. When fully cured, they seal most piping systems to their bursting point. Subscribe to our Newsletter Subscribe I accept the terms and conditions and the privacy policy
