Tube Assembly For 87K 1/4" Vertical Axis DWJ XD®

Purpose built for Flow’s Dynamic Waterjet XD cutting head, this factory bent stainless line carries the full 87,000 psi jet through the lower section of the vertical (Z) axis, the last rigid link between the swivel whip and the B‑axis stack. 

Service tip: treat the 056220‑1 tube as a consumable. Replace it whenever cone faces show fretting or after 1 000–1 500 pump hours. Installing a fresh tube with new inserts, glands and collars keeps the Dynamic XD head leak free at 87k, preserves jet coherence, and protects on/off valves and mixing chambers downstream.
