About this product
Bondloc B572 is an anaerobic pipe seal for locking and sealing metal pipes and fittings. It cures as a white paste when confined between close-fitting metal surfaces, in the absence of air, preventing loosening and leakage caused by shock and vibration. It is designed to replace traditional tapes and dopes, sealing against oils, gases, chemicals, water and steam on most metal substrates, and lubricates threads during assembly. A distinctive feature is its slow cure of up to 60 hours, allowing time to realign elbows and joints during installation. Its thixotropic paste consistency limits migration once applied. It offers good chemical and solvent resistance to ethanol, motor oil, unleaded petrol and brake fluid, and, unlike tape, will not shred or tear to contaminate the system. Supplied as a 50ml pack, suitable for use across a wide operating temperature range.
