LOCTITE® 5452, 50 ml Tube

Size Please make your selection 50 ml



LOCTITE® 5452 is a purple, thixotropic, anaerobic-curing thread sealant liquid designed for sealing threaded fittings in hydraulic and pneumatic systems. The thixotropic nature makes it suitable for large diameter pipes, and the sealant contains no fillers or particles that can interfere with a hydraulic system. It is useful with dry seal fittings such as O-Ring boss-style connectors by preventing loosening that can ultimately lead to leakage. It can be used as a sealant on mating surfaces of flare style fittings.
