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.

Questions about this item
How do I apply Vibra-TITE 440 anaerobic thread sealant and what step is commonly missed?
Clean both threads thoroughly, apply sealant to the male threads only, assemble immediately, and allow full cure before pressurising; the step often missed is skipping the degreasing of both surfaces.
Will the 50 ml bottle of Vibra-TITE 440 need replacement after opening?
Anaerobic sealant cures only when confined between metal threads and excluded from air; the liquid in the bottle remains usable for months if the cap is kept tight and the tip is clear.
What pressure or temperature limit appears first when Vibra-TITE 440 is under sustained hydraulic or pneumatic use?
The cured sealant maintains its seal up to the burst rating of the pipe or fitting; the practical limit is the component's rated pressure, not the adhesive itself.
