Hydraulic Seals for Cylinders and Pumps

A hydraulic seal is a precision-engineered component designed to prevent fluid leakage and maintain pressure within hydraulic systems such as cylinders, pumps, and valves. They are manufactured from elastomers like NBR, FKM/Viton, EPDM, HNBR, and PTFE-based compounds, and are engineered to withstand extreme pressure and temperature conditions in demanding industrial applications.

Hydraulic seals are available in premium elastomers including NBR, FKM/Viton, EPDM, HNBR, and PTFE-based compounds. Each material is selected for specific temperature ranges, chemical compatibility, and pressure requirements to ensure optimal performance in your specific application.

Yes, custom design and tooling services are available for non-standard sizes. The engineering team uses CAD and finite element analysis to develop seals matching your exact specifications with no diameter limitations, ensuring a precise fit for your application.

Standard seals ship immediately from an extensive inventory. Custom-molded seals typically require 4–6 weeks. For large or non-standard diameters, Infinite Size O-Rings offer significantly reduced lead times compared to traditional custom tooling methods, with no tooling costs required.

For high-pressure applications, T-Seals with their anti-extrusion design are recommended, and backup rings can be added to enhance standard O-ring pressure capability. A technical consultation is available to match the ideal seal design—including material, geometry, and anti-extrusion features—to your specific operating conditions and pressure requirements.

Hydraulic seals from Detroit Sealing Components serve a wide range of industries, including Oil & Gas (for drilling equipment and high-pressure pumps), Heavy Equipment & Construction (for excavators and earthmoving vehicles), Automotive Manufacturing (for hydraulic systems, shock absorbers, and power steering), and Renewable Energy (for wind turbines, solar tracking mechanisms, and hydroelectric equipment).

All hydraulic seal materials are developed and tested in an ISO 17025 accredited laboratory. Rigorous quality assurance processes including CPK/PPK analysis are performed to ensure consistent performance and adherence to industry standards, giving you confidence in the reliability of every seal.
