Description
An O-ring is a simple but brilliant seal. It sits in a groove between two parts. When assembled, it squeezes to create a tight barrier against air and oil leaks. For a vacuum pump, this seal is what keeps the powerful suction strong.
This O-ring is made from Viton, a special rubber. Viton is much more resistant to high temperatures, oils, and chemicals than standard rubber. This means it lasts longer and performs reliably in demanding environments inside your pump.
