Chesterton 286HT Bellows Cartridge Dual Seal

Meets the most stringent high temperature requirements for sealing emissions, toxic and other hazardous fluids
The 286HT is a proven performer used primarily in the chemical and petrochemical industries. The 286HT is built with AM 350 bellows material as standard, and 718 InconelĀ® as optional.
Graphite secondary seals take the place of O-rings for high temperature services related to petrochemical and chemical plant processes. 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 and solids in suspension. The tandem bellows arrangement provides maximum pressure capability and safety performance.
