Anaerobic Gasket Sealant 850 mL

This anaerobic gasket sealant cures in the absence of air to form a flexible, solvent-resistant seal between metal flanges. The purple gel formulation is designed for aluminium and steel components in automotive and industrial maintenance. It suits mechanics and engineers who need a reliable formed-in-place gasket for gearboxes, pump housings and engine casings.

Maximum Gap Fill 0.05 in

The single specification that determines fit is the maximum gap fill of 0.05 in. Surfaces must be clean, flat and within this tolerance for the anaerobic cure to develop full strength. Larger gaps will prevent proper curing and lead to leakage, so the product is not suited to worn or heavily distorted flanges.

Operating Range -10 °C to 150 °C

The sealant operates continuously from -10 °C to 150 °C, covering typical engine and transmission temperatures. Full cure requires 2 days at room temperature, with a 30-minute working window for assembly. It is not intended for high-pressure hydraulic systems or applications exceeding the stated temperature limits.

Questions about this item

How long does the 850 mL cartridge last once it is in the machine?

The 850 mL cartridge provides enough anaerobic gel for multiple gasket jobs; coverage depends on the size and number of flanges you are sealing.

What does the anaerobic cure type cap in practice?

The anaerobic cure only activates between close-fitting metal surfaces with a maximum gap fill of 0.05 in, so it will not cure in open air or large gaps.

What clearance does the 28.74 fl oz cartridge need to fit a standard caulking gun?

The cartridge is designed for standard caulking guns that accept 28.74 fl oz tubes; no special adapter is required.
