Description
This specific O-ring is made from FKM. You might also hear this material called Viton. Think of FKM as a super-tough version of rubber.
Standard rubber O-rings can break down when they get hot or touch oil. But FKM is different. It is built to handle these tough conditions.
It resists engine oils, lubricants, and many chemicals. It can also withstand high temperatures without cracking or becoming brittle.
This toughness makes it ideal for the inside of a vacuum pump. Using an FKM O-ring means you get a seal you can trust for a long time.
When you are servicing your pump, always replace old O-rings with new ones. Choosing an FKM O-ring is a smart upgrade. It ensures a reliable seal and protects your pump investment.
