Description
A Dowty Seal is a special type of washer. It has a built-in rubber ring, or lip. This lip creates a powerful, leak-proof seal when you tighten the bolt. It is much more effective than a standard flat washer.
This specific seal is an original Busch part. This means it is made to the exact size and quality your pump needs.
This seal is made with Viton, a high-performance rubber.
Viton is perfect for the inside of a vacuum pump. It can handle the heat from the pump’s motor. It also resists swelling and damage from pump oils. This means your seal will last longer and do its job better.
