87K 3/8" Cross w/o Fittings (Hexagon)

The 87K 3/8" Cross is an ultra-high-pressure four-way fitting used to branch or connect 3/8" high-pressure water lines in Flow 87,000 psi waterjet systems. It provides a compact junction point for routing pressure lines to manifolds, cutting head plumbing, gauges, bleed-down circuits, or other UHP components while maintaining a secure cone-style sealing interface.

Service tip: Inspect each port seat and tubing cone before assembly, and replace worn cones, glands, and collars whenever a high-pressure joint has been disturbed. Proper cleaning, alignment, and torque are especially important on 87K plumbing to prevent weepage, cone fretting, and premature fitting damage.
