KMT PART NUMBER:  72166738

UHP Cylinder | .875 Plunger | PRO-III | 90K | HJ-72166738


The HJ-72166738 UHP Cylinder is a precision-machined ultra-high-pressure cylinder engineered for KMT PRO-III intensifier pumps operating at 90,000 PSI (6,200 bar). Designed specifically for .875-inch ceramic plunger systems, this critical pressure-bearing component provides exceptional strength, dimensional accuracy, and long service life in demanding waterjet cutting environments.

Manufactured from premium high-strength materials and finished to exact tolerances, the HJ-72166738 UHP Cylinder ensures proper alignment of the ceramic plunger, liner, and sealing components while maintaining reliable pressure containment during continuous operation. It is used on KMT PRO-III 60 HP and 125 HP intensifier pumps, making it an essential replacement component for maintaining peak cutting performance and minimizing costly downtime.

Whether performing a complete intensifier rebuild or replacing a worn cylinder due to fatigue or scoring, the HJ-72166738 UHP Cylinder restores original pump efficiency, sealing integrity, and ultra-high-pressure performance.
