Thread Sealants for Refrigeration Systems

For use in refrigeration systems and applications exposed to strong chemicals, these sealants have excellent solvent resistance.
Anaerobic sealants don’t begin to harden until coated surfaces are threaded together, blocking exposure to air. These sealants have medium locking strength, which prevents threads from loosening with vibration and shock. They require a hand tool to unthread.
