Type 2609HTC/3609HTC

Dependable API 682/ISO 21049 Cartridge Seals

The Type 2609HTC and Type 3609HTC are dependable API 682/ISO 21049 cartridge seals that utilize two impressive design innovations by incorporating high-temperature, corrosion-resistant (HTC) sealing and unique high-temperature, live-loaded (HTL) mating ring technology in dual tandem seal arrangements. This new design vastly enhances seal face stability over conventional designs and can extend your MTBR in many services. These seals have ID and OD pressure capability and can withstand reverse pressurization. The seals come with a pumping ring standard, and the bellows have an all Inconel metallurgy for sealing the harshest high-temperature corrosive fluids. The Type 2609HTC is a dual unpressurized rotating bellows cartridge Type C, Arrangement 2. The Type 3609HTC is a dual pressurized rotating bellows cartridge seal Type C, Arrangement 3. Ideal for hot hydrocarbon refinery services.
