Description
This Busch O-ring is built for big jobs. Its large 128 mm diameter is made to seal bigger connections in your vacuum pump.
Think of it as a strong, elastic lock. It sits snugly in a groove, creating a tight barrier. This barrier stops air leaks and prevents oil from escaping.
This is vital for maintaining strong vacuum pressure. It also keeps your equipment clean and efficient.
The O-ring is made from Viton. This is a special material that is very tough. It doesn’t mind the heat and chemicals inside a busy pump. This means it won’t crack or swell easily.
Using this original Busch part gives you peace of mind. You know it will fit perfectly and work as intended.
