Type 2609HTC - 3609HTC
Dependable API 682/ISO 21049 Cartridge Seals Type 2609HTC – 3609HTC
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.

Exceptional Face Stability Type 2609HTC – 3609HTC
The HTC primary seals, patent pending, incorporate specially designed pressure compensating seal faces and thermally compliant components that provide superior seal face stability at elevated temperatures. With advanced HTL mating ring design, patent pending, seal face stability is achieved by eliminating any thermal and mechanical forces that can contribute to seal face distortion. The sealing interface remains exceptionally stable in spite of thermal changes and adapts to the wide range of temperature excursions inherent in hightemperature applications.
Corrosion Resistance
These all-Inconel ® seals are ideally suited for applications that contain organic acids (naphthenic acids) and sulfur compounds that attack most other alloys at high temperatures.
