These heavy‑duty high‑pressure rubber O‑rings are engineered for harsh high‑pressure working conditions. Available materials include NBR, EPDM, FKM and silicone, manufactured by precision compression vulcanization craft. Smooth burr‑free surface, ultra‑low compression set and strong anti‑deformation performance. NBR delivers excellent oil‑resistant under high pressure; EPDM resists steam and ozone; FKM handles high‑pressure together with high‑temperature & chemical corrosion; silicone adapts for broad temperature range. It maintains stable static and dynamic sealing to prevent medium leakage under heavy pressure load.

Suitable for hydraulic cylinders, high‑pressure pipelines, valve assemblies, pump equipment, auto hydraulic systems and heavy‑duty industrial machinery. Metric and AS568 standard sizes in stock. Custom service supports ID, OD, cross‑section, hardness, color and non‑standard OEM mould‑opening. Reliable high‑pressure sealing solution for global industrial wholesalers.
