Product Introduction
Rubber O‑rings as spare parts for hydraulic machinery are circular cross‑section elastomer sealing elements manufactured by precision compression vulcanization. Available materials include oil‑resistant NBR, high‑temp FKM, EPDM and HNBR, complying with GB/T3452.1, AS568 and JIS B2401 standards. Featuring good elasticity, low compression‑set and pressure self‑energizing sealing effect. Working temperature‑30℃‑120℃ for NBR version, withstanding system pressure up to 40MPa when matched with backup rings. Suitable for static and reciprocating dynamic sealing, effectively preventing hydraulic‑oil and medium leakage. Widely used for hydraulic cylinders, valves, pumps and pipe joints of engineering machinery, machine tools and heavy‑duty hydraulic equipment. Rich metric and inch standard sizes are kept in stock. Custom dimension, cross‑section, rubber hardness, color and OEM marking are supported per drawings or samples for hydraulic‑equipment assembly and aftermarket repair‑kit projects.
