Engineered for demanding hydraulic cylinder applications, this piston seal assembly combines a nitrile (NBR) sealing element with a reinforced nylon (PA) wear ring to deliver reliable bi-directional sealing and precise bore guidance in a single, drop-in unit.
Key Benefits
Leak-free performance — the NBR lip seal maintains consistent contact pressure across the full stroke, preventing fluid bypass even under dynamic load cycling
Reduced metal-to-metal contact — the nylon wear ring centers the piston rod and absorbs lateral forces, extending cylinder and seal service life
Temperature range — rated for continuous operation from -40 °F to +212 °F (-40 °C to +100 °C)
Easy installation — pre-assembled profile fits standard piston grooves; no bonding or secondary components required
Typical Applications
Industrial hydraulic cylinders, agricultural equipment, mobile hydraulics, construction machinery, and pneumatic/hydraulic press systems where reliable piston sealing and bore wear protection are critical.
Material Specifications
Sealing element: Nitrile Butadiene Rubber (NBR), 70–90 Shore A
Wear ring / guide ring: Reinforced Nylon (PA66 or PA46)
