Product Introduction
Durable NBR oil seals for hydraulic cylinders are reciprocating lip‑style sealing components made of nitrile butadiene rubber via compression vulcanization. Suitable for piston‑side or rod‑side installation inside hydraulic cylinders. Featuring excellent oil‑resistance, good wear‑resistance and low compression‑set. Working temperature ranges from‑30℃ to 110℃, tolerates system pressure up to 35MPa. The elastic lip generates pressure‑energized self‑sealing effect under hydraulic pressure to block hydraulic‑oil leakage. Upgrade options include FKM fluororubber for higher‑temperature working scenarios. These NBR cylinder seals follow international groove standards, widely used for construction‑machinery cylinders, forklifts, injection‑molding machines, hydraulic presses and general‑industrial hydraulic equipment. Multiple common metric sizes are kept in stock. Custom inner‑outer dimension, cross‑section profile, rubber hardness and OEM marking are supported per customer drawings or samples for equipment aftermarket repair and OEM supporting projects.
