PRODUCT DESCRIPTION
The HJ-303639 On/Off Valve Repair Kit MAXJET (Upgraded Design) is a precision-engineered, high-performance rebuild kit developed to restore and enhance the reliability of OMAX MAXJET cutting heads, including MAXJET 5 Tilt-A-Jet (TAJ) systems.
This new improved, long-lasting HJ-303639 On/Off Valve Repair Kit includes all essential wear components required to rebuild the on/off valve assembly, ensuring consistent cutting performance, precise water control, and extended service life in ultra-high-pressure waterjet systems operating up to 60,000 PSI (60K)
The following is what makes our new enhanced design premium:
🔹 Enhanced Seal Technology
- Uses high-performance sealing materials for improved resistance to pressure, heat, and abrasion
- Reduces premature wear and leakage
🔹 Reinforced Backup Ring Design
- Improved extrusion resistance under extreme 60K PSI pressure
- Extends overall seal life
🔹 Precision-Machined Valve Seat
- Optimized sealing surface for cleaner shutoff and reduced leakage
- Improves valve efficiency and reliability
🔹 Upgraded Poppet / Valve Element
- Enhanced wear resistance for high-cycle operation
- Maintains consistent valve response over time
🔹 Improved Surface Finishing
- Reduced friction between moving parts
- Smoother actuation and faster response
