O-Ring 200905 Good Quality WaterJet Pump Parts

The O-Ring 200905 is a precision-molded high-pressure sealing component specifically designed for use in Waterjet Cutting Systems, intensifier pumps, and hydraulic valve assemblies. It provides reliable leak protection, pressure retention, and durable performance under the extreme pressures and temperatures typical of industrial waterjet environments.

Manufactured from premium elastomer materials such as Buna-N (Nitrile), Viton (FKM), or EPDM, the 200905 O-ring offers outstanding chemical resistance, compression set stability, and elastic recovery. Its uniform cross-section and tight dimensional tolerance ensure a perfect seal between mating components like the check valve body, cylinder liner, or outlet manifold, maintaining hydraulic efficiency and minimizing maintenance downtime.

Capable of withstanding working pressures up to 60,000 psi (4000 bar) and temperatures ranging from -30°C to +200°C (depending on material composition), the O-Ring 200905 is ideal for both high-pressure and low-pressure sealing points within the system. It is fully compatible with KUNDA, KMT, FLOW, and OMAX WaterJet Cutting Machines, as well as other OEM hydraulic systems.

Used extensively in metal fabrication, stone cutting, ceramic machining, and composite processing, this O-ring ensures tight sealing, long service life, and stable system performance even in harsh, abrasive environments.
