Dual Port Swivel Seal Rebuild Kit | HJ-308616


The HJ WATERJET HJ- 308616 Dual Port Swivel Seal Rebuild Kit, also known as the Dual Port Swivel Replacement Package is a precision-engineered service rebuild kit designed to restore sealing performance in dual port swivel assemblies used in OMAX waterjet systems.

The HJ-308616 Dual Port Swivel Seal Rebuild Kit includes critical sealing components required to maintain a leak-free, high-pressure connection between stationary and rotating components within the swivel assembly.

Swivel systems allow for controlled movement and routing of high-pressure water lines. Over time, internal seals wear due to continuous rotation, extreme pressure, and fluid friction, leading to leaks, pressure loss, and reduced system efficiency.

The HJ-308616 Dual Port Swivel Seal Rebuild Kit restores proper sealing integrity, ensuring reliable performance and extended component life.

Designed for use with OMAX dual port swivel assemblies HJ-308620-1, HJ-308620-2 and HJ- 308620-3

 

Key Benefits

  • Eliminates Leaks – Restores proper sealing under pressure
  • Maintains System Efficiency – Prevents pressure loss
  • Extends Swivel Life – Reduces wear on rotating components
  • Supports Continuous Operation – Reliable performance in motion
  • Cost-Effective Repair – Avoids full swivel replacement

 

Applications

  • Abrasive waterjet cutting systems
  • High-pressure fluid routing systems
  • Industrial CNC cutting environments
  • Continuous production operations 

 

Frequently Asked Questions | HJ-308616


1. What is HJ Waterjet part HJ-308616?
HJ Waterjet HJ-308616 is a direct replacement for OMAX 308616 Dual Port Swivel Seal Replacement Package used to replace the internal seals and O-rings in a dual-port swivel.

2. What OMAX swivel assemblies does HJ-308616 fit?
The kit is used with OMAX 308620-1, 308620-2, and 308620-3 dual-port swivel assemblies.

3. Is HJ-308616 a complete swivel assembly?
No. HJ-308616 is a seal replacement/rebuild package, not the complete swivel. It is intended to service the sealing components inside the swivel.

4. When should the HJ-308616 seal kit be replaced?
It should generally be replaced when the dual-port swivel begins showing leakage, seal wear, pressure loss, or deteriorated swivel performance. Replacing worn seals can prevent further damage to the swivel.

5. Can I rebuild the swivel instead of replacing the entire swivel?
Yes. That is the primary purpose of HJ-308616. If the swivel body and other major components remain serviceable, replacing the seals can restore the swivel without replacing the complete assembly.  

6. Is HJ-308616 considered a rebuild kit?
It is best described as a Dual Port Swivel Seal Replacement Package. Many waterjet suppliers also market it as a dual-port swivel rebuild kit or seal replacement kit.

7. What is the difference between HJ-308616 and HJ-311849?
They service different swivel designs. HJ-308616 is for the Dual Port Swivel, while HJ-311849 is the Dual Axis Swivel Rebuild Kit.

8. Is HJ-308616 used on abrasive waterjet machines?
Yes. The kit is associated with OMAX/Maxiem waterjet swivel assemblies used for high-pressure water routing in abrasive waterjet cutting systems.

9. Should I replace just one seal or the complete HJ-308616 kit?
For a swivel that is already being serviced, replacing the complete seal package is generally preferable because the kit addresses the associated seals, backup ring, and O-rings together rather than replacing only one worn component. 

10. Can a worn HJ-308616 kit cause waterjet downtime?
Yes. A leaking or degraded swivel seal can require the machine to be taken out of service, particularly if leakage becomes significant or the swivel can no longer maintain proper high-pressure sealing.
