Product Description
The HJ WATERJET Hydraulic Piston Assembly Repair Kit, .875 Plunger, 60K (HJ-05115951) is a complete rebuild solution designed for high-pressure waterjet intensifier systems operating up to 60,000 PSI (4,100 bar).
The HJ-05115951 Hydraulic Piston Assembly Repair Kit is used to repair the hydraulic piston assembly (HJ-05132253), restoring the core mechanism that drives the reciprocating motion of the intensifier.
Engineered for .875 (0.88) plunger systems, the HJ-05115951 Hydraulic Piston Assembly Repair Kit ensures efficient hydraulic performance, stable pressure output, and extended pump life in demanding industrial environments.
