O-ring activated piston seals are designed for high-performance sealing in both static and dynamic applications. These seals use an O-ring as the energizing element, creating a tight and responsive seal that significantly reduces leakage and enhances system efficiency—especially in space-constrained or high-pressure environments. Ideal for hydraulic pistons, these o-ring piston seals provide exceptional sealing performance and longevity, even under demanding operating conditions. The addition of a backup ring O-ring offers increased resistance to extrusion and pressure spikes, ensuring long-term reliability. Whether you’re working with industrial equipment or mobile hydraulic systems, our o-ring activated seals for hydraulic pistons deliver consistent results. These high-pressure o-ring piston seals with backup rings are ideal for applications requiring secure static sealing with o-ring activated designs and precision control.
