9/16 High Pressure Collar A-3951 Good Price Waterjet Coil Parts

The 9/16 High Pressure Collar (Part No. A-3951) is a precision-engineered stainless steel retaining collar designed for industrial Waterjet Cutting Systems and high-pressure hydraulic assemblies operating up to 60,000–100,000 PSI. Used together with the high-pressure gland and tubing, this collar ensures secure mechanical retention and sealing integrity in all high-pressure connections.

Manufactured from premium seamless 304/316 stainless steel, the A-3951 collar offers outstanding corrosion resistance, tensile strength, and fatigue durability under continuous high-pressure operation. It is CNC-machined to exact tolerances, ensuring perfect alignment with the gland (A-3950) and 9/16 HP tubing, delivering a tight, vibration-resistant fit that prevents tube slippage and maintains leak-free performance even under pulsating loads.

The 9/16 High Pressure Collar A-3951 is fully compatible with leading waterjet brands, including KMT, FLOW, BFT, WSI, and APW, serving as a direct OEM-equivalent replacement or upgrade component. It is commonly installed in intensifiers, manifolds, accumulators, and cutting head assemblies, where precise and secure high-pressure tube retention is critical.
