Description
A Dowty Seal is a special type of washer. It has a rubber O-ring bonded to a metal outer ring. You use it under bolts or plugs. When you tighten the bolt, the rubber squeezes and creates a tight seal. It stops oil from leaking out and air from leaking in . Your vacuum pump has many threaded connections. Oil lines, drain plugs, and other fittings all need to seal tightly. A regular metal washer might leak. A Dowty Seal gives you a reliable seal every time. It is designed specifically for hydraulic and oil systems.
