Dual Balanced Drive Inline Adjusting Scuba Tool with SPG

The Dual Balanced Drive Inline Adjusting Scuba Tool with SPG is a professional second-stage regulator servicing tool manufactured by ScubaGaskets.

It combines slotted and hex-drive orifice adjustment with a pressure-balanced design. The tool allows technicians to fine-tune compatible second-stage regulators while connected to a pressurized air supply.

Its dual-drive system makes it suitable for a wide range of regulator designs.

Key Features

1. Dual-Drive Compatibility

The tool supports both slotted and hex-broached regulator orifices.

• Slotted drive for compatible adjustable orifices, including older narrow-slot designs.
• Tapered hex drive for 3/16-inch (approximately 5 mm) broached orifices.
• Reversible fitting allows technicians to switch between slotted and hex-drive configurations.

2. Pressure-Balanced Adjustment

The internal flow-through spool design equalizes air pressure between the hose and second-stage regulator.

This pneumatic balance helps the adjusting mechanism move smoothly in either direction. It also allows the tool to maintain its position during adjustment without continuous hand pressure.

3. Deep-Reach Adjustment

The adjustable knurled knob can be positioned off-centre when additional reach is required.

This feature helps the slotted drive access deeper orifices in certain second-stage regulator designs.

4. Integrated SPG Pressure Gauge

This version includes an SPG pressure gauge assembly.

The gauge mounts at the end of the tool, allowing pressure monitoring while performing regulator adjustments.

A friction O-ring allows the technician to orient the gauge for easier viewing.

5. Replaceable Threaded Ends

The tool uses chrome-plated brass threaded ends.

These components can be replaced if their threads become worn, extending the practical service life of the tool.
