Industrial Fluid Power Seals

Hydraulic & Pneumatic Seals

Sealing Devices supplies high-performance hydraulic seals, pneumatic seals, spring-energized seals, and custom fluid power sealing solutions engineered for high-pressure industrial systems.

From hydraulic cylinders and pumps to pneumatic actuators and accumulators, our sealing solutions are designed to withstand pressure cycling, fluid compatibility challenges, temperature extremes, and demanding duty cycles.

Applications

Hydraulic Cylinders and Motors

We supply rod seals, piston seals, wear rings, wipers, and backup rings designed for industrial presses, material handling systems, and more for applications that must withstand high pressures (often exceeding 5,000 psi), dynamic movement, and exposure to hydraulic fluids.
Pneumatic Systems

Pneumatic seals operate in compressed air environments and require low-friction materials to minimize wear and improve cycle life. We provide U-cups, O-rings, bonded seals, and custom elastomer components for air cylinders, automation systems, robotics, and process equipment.
Accumulators

Accumulators rely on seals to safely store and release pressurized fluid energy, which must endure repeated pressure cycling while preventing fluid or gas leakage. We support sealing solutions for bladder accumulators, piston accumulators, pressure vessels, and energy storage systems.
Valves, Pumps & Fittings

Proper sealing is essential for regulating the fluid direction, pressure, and flow. We provide sealing components engineered for control valves, hydraulic pumps, manifolds, and high-pressure fittings.
