Description
This seal is made from Viton (also called FKM). Viton is a high-performance rubber that is much tougher than standard materials. It can handle the high temperatures, constant friction, and exposure to oil that happens inside a running pump. Viton is also resistant to many chemicals, so it won’t break down easily. This shaft seal has a very specific and important job. It fits around the rotating shaft where it exits the pump housing. As the shaft spins, this seal maintains constant contact to stop air from leaking in and oil from leaking out. Think of it like the rubber ring around a blender blade. Without it, your smoothie would leak everywhere. In your vacuum pump, this seal is essential for maintaining strong, steady performance.
