Vibra-TITE 440 Anaerobic Thread Sealant 50 ml

Vibra-TITE 440 Anaerobic Thread Sealant

Vibra-TITE 440 is an anaerobic thread sealant designed for hydraulic and pneumatic systems. The purple compound cures in the absence of air to lock and seal metal threads. It suits maintenance technicians and engineers who need reliable sealing on pipe fittings and valves. The 50 ml bottle provides enough material for multiple assembly tasks.

Thermals, Noise and Power Draw

As a chemical sealant, this product generates no heat, produces no audible noise and draws no electrical power during application or curing. The anaerobic formulation remains liquid until confined between metal surfaces, where it polymerises into a solid thermoset plastic. No external energy source is required for the sealing reaction to complete.

Behaviour Under Sustained Load

Once cured, the sealant maintains its integrity under continuous system pressure and vibration. The anaerobic bond resists loosening caused by thermal cycling and mechanical shock in hydraulic and pneumatic circuits. It fills thread voids completely to prevent leakage paths from forming over extended service intervals. The compound is not intended for use on plastic threads or in oxygen-rich environments.
