Description
This Busch part is made to the exact size needed. It will fit perfectly in the designated groove on your pump.
When you install it, it forms a strong, long-lasting barrier. This keeps the vacuum strong and prevents any leaks.
Some parts of your vacuum pump get very hot. In these high-heat areas, a standard rubber or composite gasket might not work. It could burn, crack, and fail.
For these tough spots, you need a different kind of seal. You need a copper ring gasket.
Copper is a soft, malleable metal. When you tighten the pump parts together, the copper ring compresses. It flows into any tiny imperfections on the metal surfaces.
