Chesterton 286 Metal Bellows Cartridge Dual Seal

Balanced Bellows Seal Design for Harsh Chemical Services


​​​​​​​​​The Chesterton 286 Dual Cartridge-Style Bellows Seal is designed ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​for applications in which the process fluid is incompatible with common elastomers or where the cost of custom O-Rings is prohibitive. This bellows seal is used primarily in the chemical and petrochemical industries.

The high-strength, low-spring-rate bellows core delivers low-heat generation and reliable sealing performance. The self-cleaning rotary bellows design will reduce the clogging associated with sealing fluids with solids in suspension. The tandem bellows arrangement provides maximum pressure capability and safety performance.​​​​​​​
