Description
This is a Busch O-ring. It is designed to fit specific connections in your Busch vacuum system. Its job is simple but vital: to create a perfect seal.
Without a good seal, air can leak into the system. This leak can make your pump work harder. It can reduce its power and efficiency.
This O-ring is made from Viton. Viton is a special rubber that is very strong. It can handle high temperatures without cracking. It also stands up to oil, grease, and many chemicals much better than standard rubber.
