On/Off Valve Repair Kit Maxjet 303639 – Replacement for OMAX Waterjet Systems

The On/Off Valve Repair Kit Maxjet 303639 is designed to restore the performance and reliability of OMAX Maxjet cutting heads, including Maxjet 5 Tilt-A-Jet systems. This precision maintenance kit contains the essential wear components required to rebuild the on/off valve assembly and maintain consistent waterjet cutting performance.

In high-pressure waterjet systems, the on/off valve plays a critical role in controlling the start and stop of the cutting stream. Over time, internal components such as the valve seat, seal assembly, and stem experience wear due to extreme pressure and constant cycling. The 303639 repair kit provides the key replacement parts needed to restore proper sealing, smooth valve operation, and accurate cutting control.

Designed to meet OEM-equivalent specifications, this kit ensures reliable compatibility with OMAX cutting heads while helping reduce maintenance costs and machine downtime.
