Pistons, Rods & Seals Kits

About pistons, rods & seals kits

Pistons, Rods & Seals Kits encompass the critical components required for the assembly, repair, or refurbishment of hydraulic and pneumatic cylinders. Piston assemblies typically include the piston head, which translates fluid pressure into mechanical force, often featuring an integral or attached piston rod connection. Piston rods, frequently specified as chrome rod, are precision-ground and polished steel shafts, hard chrome plated to resist wear, corrosion, and provide a low-friction sealing surface. They are characterized by their diameter, length, and end-threading (e.g., UNF, UNC, metric fine) for attachment to clevises or other linkages. Seal kits comprise a variety of elastomeric and thermoplastic components, including piston seals (e.g., U-cups, O-rings, compact seals), rod seals (e.g., U-cups, chevron sets), wipers, and wear rings. These seals are crucial for preventing fluid bypass and external leakage, and their material selection (e.g., Nitrile, Viton, Polyurethane, PTFE) depends on operating temperature, pressure, and fluid compatibility. Rebuild parts can also include cylinder barrels, end caps, and mounting hardware, ensuring a comprehensive solution for cylinder maintenance.
