Type 1604HTC
Single Stationary Welded Metal Bellows API 682 Cartridge Seal Type C, Arrangement 1
The Type 1604HTC is an API 682/ISO 21049 qualified single stationary bellows cartridge seal Type C, Arrangement 1. The Type 1604HTC incorporates all-Inconel HTC technology to reliably seal high-temperature corrosive fluids. The seal includes a segmented spring-loaded carbon throttle bushing for effective containment with a retained mating ring for vacuum service. The cartridge seal also incorporates a steam guide for effective use of a quench (steam) that helps eliminate coking problems often associated with hot hydrocarbon applications. The Type 1604HTC is able to handle higher-speed applications.
Product Description Type 1604HTC
- Type 1604HTC – Single stationary bellows cartridge seal Type C, Arrangement 1
- Type 2609HTC – Dual unpressurized rotating bellows cartridge seal Type C, Arrangement 2
- Type 3609HTC – Dual pressurized rotating bellows cartridge seal Type C, Arrangement 3
These dependable API 682 cartridge seals utilize two impressive design innovations by incorporating high-temperature corrosion resistant sealing (HTC) and unique high-temperature live-loaded (HTL) mating ring technology in dual seal arrangements. This new design vastly enhances seal face stability over conventional designs and can extend mean time between repair (MTBR) in many services.

Exceptional Face Stability – Type 1604HTC
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.
