Polymer Seals - Industrial Grade Sealing Solutions

A thermoplastic seal is made from materials such as TPE, TPU, Santoprene, or Hytrel that can be melted and reshaped when heated. Unlike thermoset rubbers, thermoplastics offer recyclability and consistent dimensional properties. DSC's TPE & TPU seals are widely used in NVH applications, CV joint boots, and protective covers for consumer electronics and automotive components.

DSC offers seals in a comprehensive range of materials including NBR, FKM/Viton, EPDM, HNBR, VMQ/Silicone, PTFE-based compounds, FEPM/FFKM, TPE, TPU, and Santoprene. Material selection depends on the chemical environment, temperature range, pressure requirements, and regulatory compliance needs of the application.

Yes. Detroit Sealing Components provides full custom design and tooling services for non-standard seal geometries. Using computer-aided design (CAD) and finite element analysis (FEA), DSC engineers can develop seals for unique bore sizes, pressure ratings, and environmental conditions. Custom profiles including asymmetric, specialty, and infinite-size configurations are all available upon request.

Industrial polymer seals serve a broad range of sectors including oil & gas, automotive, aerospace, food & beverage, medical & pharmaceutical, renewable energy, agriculture, semiconductor manufacturing, drinking water systems, and general industrial equipment. Each industry has specific material compliance requirements and operating conditions that drive seal selection.

Yes. DSC's Sanitary & Drinking Water Seals comply with FDA CFR 177.2600, NSF 61, NSF 42, WRAS, W270, AS/NZS 4020, ACS, and UBA (KTW) standards. Medical Seals are manufactured with USP Class VI certified materials in controlled cleanroom environments, minimizing contamination risk for pharmaceutical and medical device applications.

O-rings have a circular cross-section, while X-rings (also called quad-rings) feature a 4-lobed cross-section. X-rings provide additional sealing surfaces, greater cross-sectional stability in glands, and lower friction due to reduced sealing force requirements. They outperform standard O-rings in dynamic rotary and reciprocating applications and resist twisting and spiral failure in service.
