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.

High-Temperature Clean Room Silicone
Gaskets for Quick-Clamp Tube Fittings

These gaskets meet Fed. Std. Class 10,000 and ISO Class 7 clean room requirements.

High-Temperature Silicone Gaskets
for Quick-Clamp Tube Fittings

Even as temperatures rise, these silicone gaskets ensure a tight seal in quick-clamp stainless steel sanitary tube fittings.

High-Temperature Silicone Gaskets with
Screen for Quick-Clamp Tube Fittings

A corrosion-resistant 316 stainless steel screen provides inline straining.

High-Temperature Silicone Gaskets with
Perforations for Quick-Clamp Tube Fittings

Use these perforated gaskets to filter liquids and dry materials, as well as create a tight seal in quick-clamp stainless steel sanitary tube fittings. Made of silicone, they handle temperatures up to 450° F, so they’re good for heated ingredients and clean-in-place (CIP) processes.

Ultra-Chemical-Resistant PTFE Gaskets with
Perforations for Quick-Clamp Tube Fittings

These chemical-resistant gaskets have a perforated plate that filters, separates, and strains liquids or dry materials in your line.

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.
