ring Gasket, Becker, U Series, Part# 300158

Your Becker U Series pump has many seals inside it. This one is a ring gasket, also called an O-ring. It fits around shafts or between parts to create a tight seal. Its job is simple but very important. It stops oil leaks and air leaks .

This gasket is made of Viton. Viton is a special type of rubber . It is not like regular rubber. Here is what makes Viton better:

• It resists heat. Your pump gets hot when it runs. Regular rubber gets hard and cracks. Viton stays soft and flexible.

• It resists oil. The inside of your pump is full of oil. Viton does not swell or break down when it touches oil.

• It resists chemicals. Some applications have harsh chemicals. Viton handles them better than regular rubber.

This means a Viton gasket lasts longer and seals better than a standard rubber gasket
