Product Description
The HJ WATERJET HP Cylinder Liner, 1.125 Plunger, 60K (HJ-72110945) is a precision-machined component designed for high-pressure waterjet intensifier systems operating up to 60,000 PSI (4,100 bar).
Installed inside the high-pressure cylinder, the HJ-72110945 HP Cylinder Liner provides the primary wear surface for the reciprocating 1.125 plunger, ensuring smooth operation, proper sealing, and consistent pressure generation.
This part replaces legacy numbers including HJ-05144555, HJ-72440945 and is required when upgrading or servicing newer sealing head assemblies such as HJ-72110979.
