Gasket, Busch R5 EVA CB0250B – Part # 480106270

Gaskets are the seals between metal parts. They stop air from leaking in. They also stop oil from leaking out. When a gasket gets old, it becomes hard and brittle. Then it cannot seal anymore. That is when you lose vacuum power.This gasket is not like a regular rubber gasket. It has a graphite coating on one side . Why does that matter? The graphite helps the gasket slide into place without tearing. It also helps create a tighter seal. Many mechanics prefer graphite coated gaskets because they last longer.

This gasket is used in the Busch R5 series. The R5 is one of the most popular vacuum pump lines in the world. These pumps are used in many industries. They run packaging machines. They power medical equipment. They help make electronics. So keeping them in good shape is very important.

This specific part (480106270) works with the CB0250B pump model . It is often included in larger maintenance kits. But if you only need this one gasket, buying it separately saves you money.
