Which product to be used for close fittings?

For close fittings, it is recommended to use an anaerobic sealer. KENT Rapid Gasket is an anaerobic gasketing compound specially developed for the sealing of close fitting gaskets and flange assemblies. Rapid Gasket is used for sealing fuel and water pumps, split crank cases on engines, gearbox covers, thermostat housings, air compressor end caps, engine timing cam covers onto blocks, pump couplings, fuel tanks on small implements, chain saws, lawn mowers, etc. If too much Rapid Gasket is applied and is pressed out of the fitting, the excess will dissolve and as such will not clog the system. Additional benefit – it comes in a pressurized can, which makes application easy.
