Parco is your convenient source for custom O-rings. In addition to making all 369 standard sizes, we also manufacture hundreds of non-standard sizes and custom metric sizes. If Parco does not have a mold for a non-standard size or a particular metric size, we can make one for you.
Parco’s non-standard O-rings are available in the following elastomers:
- Ethylene-Propylene (EPR, EPDM)
- Fluorocarbon (Viton®, Tecnoflon®, 3M Fluoropolymers)
- Hydrogenated Nitrile (HNBR)
- Nitrile (Buna-N)
- Perfluorocarbon (FFKM)
