Description
It is crafted from FKM, a premium sealing material. You might know it better by the brand name Viton. This material is the key to its strength.
Ordinary rubber seals can fail. They can swell in oil, crack from heat, or break down from chemicals. An FKM O-ring stands strong. It keeps its shape and flexibility.
This makes it ideal for vacuum pumps. It seals areas exposed to pump oil, grease, and heat from operation. It prevents messy leaks and helps maintain system pressure.
The dimensions are precise: 87mm inside diameter and 3mm thick. This exact size ensures it will fit correctly in its designated groove. A proper fit is what creates a leak-proof seal.
Keeping a few of these on hand is smart. They are common wear items. Replacing a hardened or flattened O-ring during service can prevent future downtime and bigger issues.
