Product Description


The HJ WATERJET Hydraulic Piston Assembly Repair Kit, 1.125 Plunger, 60K (HJ-80085079) is a complete rebuild solution designed for high-pressure waterjet intensifier systems operating up to 60,000 PSI (4,100 bar).

This kit is specifically engineered to restore the hydraulic piston assembly, which drives the reciprocating motion of the intensifier and is critical for maintaining consistent pressure output and system efficiency.

Designed for 1.125 (1-1/8") plunger systems, this kit is widely used in SL-IV, SL-V, SL-VI, and other 60K intensifier platforms.
