These are service parts for the Premium Valves sold by Dive Gear Express. The o-rings are oxygen compatible and supplied by Dive Gear Express.

The DGX Premium Valve Service Kit contains the Plug and Seat Assembly, o-rings and teflon packing needed to service one DGX standalone or in-line valve. Order two kits to service an H-valve configuration, and order three kits to service a dual-outlet manifold with isolator. Depending on the valve model and configuration you will have a few o-rings left over.

The o-ring sizes used by the valves and included in the service kit are:

  • Bonnet Nut V015
  • Stem V010
  • DIN Insert V112 (two)
  • Cylinder Neck V214
  • Modular Plug V012 (two)

Designed to North American safety standards, DGX valves always include a PRD (Pressure Relief Disk) assembly aka "burst disk" with a 3/8-24 UNF thread PRD opening on the end opposite the handwheel for standalone models, or the back for modular models, or the top for inline models. Pressure relief disks are described by their release pressure, not the cylinder service pressure. This PRD is clearly marked with the release pressure in PSI on the hex head and requires 100-120 in-lb of torque for installation. If the PRD is installed in the scuba valve too tightly it will rupture prematurely, and if installed not tightly enough it will leak. Dive Gear Express recommends a new safety assembly be installed by a qualified technician whenever the cylinder is hydro tested and annually if the cylinder is known to have been overfilled.

Tek Tip Warning Image WARNING

Availability of sub-assemblies and components, repair parts, specialized tools and maintenance manuals does not imply qualification to assemble and/or service scuba equipment.

Most authorized dealers are able to perform warranty, repair and service work on your equipment. Service by other than an authorized dealer may void the warranty. Improper service of dive equipment can lead to serious injury or death.

Dive Gear Express recommends that divers participating in more advanced technical and exploration type diving be trained in equipment service. We recommend that non-qualified individuals seek professional training/mentoring before attempting repairs or servicing on any diving equipment.
