The ST20-R profile is a high-performance double-acting compact seal designed as a superior alternative to standard O-rings in hydraulic and pneumatic systems. Engineered for pressures up to 700 bar, it features an interference fit on the outside diameter and integrated back-up rings that are activated by internal material stress to prevent gap extrusion. This space-saving design is tailor-made to fit existing O-ring grooves, providing excellent static and minor dynamic sealing without hardware revisions. Verified by SGS and TUV reports, our bespoke ST20-R solutions ensure leak-free integrity for critical armatures in offshore and aviation applications.

- EXTRUSION PROTECTION: The activated back-up rings significantly reduce the risk of gap extrusion and prevent twisting, even under pulsating high-pressure conditions.
- SEAMLESS RETROFIT: Our custom ST20-R geometry is tailor-made to fit standard O-ring grooves, allowing for a direct performance upgrade without re-machining hardware.
- RELIABLE LOW-PRESSURE SEAL: The internal preload achieved by our bespoke material selection ensures a superior sealing effect at both low and high pressures (up to 700 bar).
Our High-Precision Lathe-Cut process ensures each ST20-R compact seal adheres to tight tolerances, providing a perfect fit for critical hardware. With no-mold required technology, we provide cost-effective small batches and low MOQ test samples with zero-tooling lead times, accelerating your development cycle. As an ISO 9001 certified factory, we provide direct factory prices for all bespoke sealing projects.
