U Cup Seal 202398 High Pressure WaterJet Pump Parts

The U Cup Seal 202398 is a high-performance hydraulic sealing element designed for ultra-high-pressure Waterjet Intensifier Pumps. It plays a critical role in preventing hydraulic fluid leakage and maintaining consistent pressure within the plunger and cylinder assembly. Made from premium polyurethane or PTFE-reinforced material, this seal provides excellent wear resistance, elasticity, and pressure stability, ensuring long-term reliability even in continuous, heavy-duty cutting environments.

The 202398 U Cup Seal features a unique U-shaped lip profile that expands under pressure to create a tighter seal. This self-energizing design offers superior sealing performance and reduces friction between moving parts, helping to extend the lifespan of both the seal and the plunger surface. It is specifically engineered to perform in hydraulic systems operating up to 60,000 psi (4,100 bar).

Fully compatible with major waterjet brands including KMT, FLOW, OMAX, WSI, and BFT, the U Cup Seal 202398 is an essential component for maintaining pump integrity, pressure stability, and efficient cutting performance.
