Metallic slotted inline second-stage regulator adjustment tool featuring an integrated circular pressure gauge.

The Slotted Inline Second-Stage Adjustment Tool with Gauge is a premium, professional-grade diagnostic instrument engineered to optimize scuba regulator tuning. Developed and trusted by Scuba Service Tools, this dual-purpose workshop tool links directly inline between the low-pressure hose and the second-stage demand valve. It allows technicians to seamlessly adjust breathing resistance and read intermediate pressure simultaneously while the system remains fully pressurised. By saving valuable bench time, it eliminates the need to constantly depressurise equipment between adjustments. Featuring a precision flat blade tip, it offers universal compatibility across a massive selection of modern, slotted-orifice regulator brands.

How It Works:

The tool is installed directly between the second-stage regulator inlet and the low-pressure supply hose. Once gas flow is turned on and pressurized, the integrated pressure gauge provides a continuous reading of the first-stage intermediate pressure. The technician then engages the internal flat blade drive directly into the slot of the second-stage air inlet orifice. By turning the external adjustment knob, the orifice is precisely positioned to balance spring tension against the internal valve lever, achieving flawless breathing performance under live pressure simulation.

Key Features & Specifications:

Simultaneous Testing & Tuning: Provides live intermediate pressure monitoring while enabling real-time adjustments to the regulator orifice.
Universal Slotted Blade: Features a 0.275-inch (0.7-mm) flat screwdriver tip designed to fit nearly all standard slotted orifices without slippage.
Extensive Brand Compatibility: Fits an incredibly wide array of manufacturers, including Scubapro, Apeks, Aqualung, Atomic, Cressi, Hollis, Oceanic, Sherwood, and many others.
Commercial Workshop Grade: Built to rigorous standards and relied upon daily by professional diving service departments for modern regulator lines.
