9/16 High Pressure Straight Coupling A-0780-3 Waterjet Coil Parts
The 9/16 High Pressure Straight Coupling (Part No. A-0780-3) is a robust, precision-engineered stainless steel connector designed for industrial Waterjet Cutting Systems and hydraulic pressure circuits operating up to 60,000–100,000 PSI. It provides a secure, leak-free connection between two 9/16-inch high-pressure tubes, ensuring consistent water flow and reliable system performance under extreme pressure conditions.
Crafted from premium seamless 304/316 stainless steel, the A-0780-3 coupling offers exceptional corrosion resistance, fatigue durability, and dimensional accuracy. Each end is CNC-machined and mirror-polished to achieve perfect sealing and alignment, while the straight-through flow design minimizes turbulence, pressure loss, and vibration — ensuring maximum efficiency and smooth operation in continuous high-pressure use.
This high-pressure coupling is fully compatible with major waterjet brands such as KMT, FLOW, BFT, WSI, and APW, serving as a direct OEM-equivalent replacement for standard 9/16 couplings used in intensifiers, accumulators, manifolds, and cutting head assemblies. Its durable construction and precise fit make it ideal for both maintenance and new system installations.
