Chesterton 186 Bellows Cartridge Single Seal

Suited for harsh chemical services that can cause difficulty with other seals
The 186 welded metal rotary bellows can enhance reliability in some applications by minimizing O-ring concerns. This 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 and solids in suspension.
