Seal and damp vibration in high-temperature equipment with these rings. Made of silicone foam, they maintain their flexibility across a wide range of temperatures. This foam has closed-cell construction, which restricts water, air, and gases from being absorbed. Rings have a crisscross texture that provides a nonslip gripping surface.

Chemical-Resistant Made-to-Order Round Belts

Outer Circumference

In addition to chemical resistance, these belts also provide increased abrasion resistance over heavy duty round belts. Also known as O-ring and endless belts, they come ready to use.

To Order: Please specify outer circumference in 1/4" increments.

Round Belting

This belting has a smooth, easy-to-clean surface. Good for light duty conveying and power-transmission applications, it is chemical and abrasion resistant and creates stronger connections than hollow-core belting. Join the ends with round belting connectors (sold separately) or use a welding kit.
