About Sizing Belts

Ultra-Chemical-Resistant FEP-Encapsulated
Viton® Fluoroelastomer O-Rings

Unlike silicone, the Viton® fluoroelastomer core will continue to ward of chemicals should the FEP casing wear away.

Ultra-Chemical-Resistant
FEP-Encapsulated Silicone O-Rings

The FEP casing on these O-rings provides the same level of resistance to harsh chemicals as PTFE O-rings, but the core material is soft to make these O-rings more compressible.

High-Temperature Clean Room Silicone O-Rings

Made and bagged in an ISO Class 7 (Fed. Std. Class 10,000) clean room, these are the highest purity high-temperature O-rings we offer.

Round Belts

Made of polyurethane, these belts resist chemicals and abrasion.

Chemical-Resistant Made-to-Order Round Belts

In addition to chemical resistance, these belts also provide increased abrasion resistance over heavy duty round belts.

Quick-Hook Twisted Round Belts

Install these belts without dismantling your drive shafts—hook the ends together with the attached stainless steel connector.

Round Belting

This belting has a smooth, easy-to-clean surface.

Quick-Connect Hollow-Core Round Belting

The hollow core of this polyurethane belting allows you to join the ends without trimming, welding, or using special tools.
