These seal sizes are our most commonly used plumbing, heating, automotive, pneumatic and hydraulic applications. If you don't see the size you need, check out our left navigation menu and search by cross-sectional size.

Nitrile O-rings are the most common seal type, and they offer excellent temperature resistance and chemical compatibility for a variety of applications. This list is for compliant metric O-rings and we are adding new sizes all the time.

We are proud of these three values:

 Quality - All our products are inspected and packaged in a controlled environment. We remove up to 99.5% of defective seals before packaging

Value - We work with our suppliers to reduce costs and pass these savings on to our customers

Accuracy - Before launching a new product line, all products are size-checked to ensure they are exactly the size you need.
