The fluid power industry powers everything from construction and injection molding equipment to off-highway machinery and aerospace systems. These systems use pressurized fluids—hydraulic or pneumatic—to perform mechanical work, and reliable seals are essential to their performance.
North Coast Seal provides sealing solutions that:
We offer a wide range of seals, including O-rings, piston seals, rod seals, rotary seals, and more, to match your system's demands. For the electrical control side of fluid power systems, we also supply UL 50E enclosure gaskets for control cabinets and equipment enclosures.
Seal performance depends on material selection. We offer compounds that handle heat, pressure, abrasion, and chemical exposure across a range of hydraulic and pneumatic applications.
Our most common fluid power sealing materials include:
Not sure which material is right? We can help.
Hydraulic systems typically use O-rings, piston seals, rod seals, and wipers made from nitrile rubber, polyurethane, or FKM. These seals must withstand high pressure and resist hydraulic fluids and heat.
Hydraulic systems deal with higher pressures and fluid leaks, so seals must resist compression and extrusion. Pneumatic seals operate at lower pressure but must handle rapid movement and air-tight sealing without lubrication.
Polyurethane, Viton®, and PTFE are commonly used in high-pressure applications due to their durability, chemical resistance, and mechanical strength.
We’ll evaluate your system’s fluid type, pressure, temperature range, and motion type to recommend the ideal sealing solution for your application.
Fluid power systems often include electrical control components such as solenoid valves, pressure transducers, and PLC control panels. For these enclosures and control cabinets, UL-recognized rubber gaskets and control panel seals support electrical safety compliance.
