Product Description


The HJ WATERJET EnduroMAX Pump Minor Maintenance Kit (HJ-308308) is a precision-engineered preventive service kit designed to maintain optimal performance in OMAX EnduroMAX intensifier pumps.

This kit includes essential wear components required for routine maintenance intervals, helping restore proper sealing, check valve performance, and pressure consistency without the need for a full rebuild.
