Hydraulic Seals
Seals
Hydraulic seals play a critical role in retaining hydraulic fluids, excluding contaminants, and maintaining hydraulic pressure in demanding systems.
At Sealing Devices, we offer a wide range of hydraulic seal solutions designed to meet your specific needs, with options available in various plastics and high-durometer rubbers to resist seal extrusion and minimize friction.
Our Trusted Suppliers
Sealing Devices is proud to partner with Freudenberg, Parker, and Trelleborg to deliver high-performing and reliable hydraulic sealing solutions for any application.
Design Specifics
Our hydraulic seals come in four key types: wiper, rod, wear, and piston seals. Each prevents leakage and the ingress of external contaminants by sealing a different part of the hydraulic or pneumatic system, from the ram-rod to the cylinder to the piston. The combination of flexible designs and highly resilient materials ensures these components can maintain a complete seal amid repeated motion and withstand high pressures without breaking.
How Hydraulic Seals Work
Each hydraulic seal protects a different area within a hydraulic cylinder and piston system to keep parts in place and stop fluids in one zone from entering another. By combining slight variations in design and materials, the overall system of seals protects the entire machine without sacrificing any one component for the sake of simplicity.
