Tube Assembly For 87K Attenuator U-Shape

A factory-formed ultra-high-pressure tube used to route 87,000 psi water through the attenuator circuit on compatible Flow HyperJet® pump systems. Its U-shaped geometry is designed to match the OEM plumbing path, helping maintain proper alignment between high-pressure ports while reducing side load on cone-style sealing connections. This assembly is best replaced when the original tube shows cone fretting, distortion, scoring, leakage, or damage from repeated installation cycles.

Service tip: Always inspect mating cone seats, glands, collars, and port faces when replacing an attenuator tube. Proper alignment is critical on 87K plumbing; forcing the tube into position can create side loading, premature cone wear, and high-pressure leakage.
