The Hex Inline Second Stage Adjustment Tool is an essential instrument for scuba technicians, specifically designed to streamline the tuning of breathing resistance on second-stage regulators. Manufactured and extensively field-tested by Scuba Service Tools, this premium workshop tool allows for precise, real-time adjustments while the low-pressure (LP) hose remains fully pressurised. By eliminating the tedious cycle of depressurising, adjusting, and repressurising the system, it significantly increases workshop efficiency and accuracy. Crafted to meet professional standards, its durable design features a hexagonal adjusting tip that effortlessly interfaces with a wide selection of modern demand valves, making it a reliable addition to any dive centre or individual technician's kit.
How It Works:
The tool connects directly inline between the low-pressure regulator hose and the second stage regulator inlet. Once the scuba system is pressurised, the technician can slide and engage the internal hexagonal adjusting rod directly into the second stage orifice. Turning the external adjusting knob allows the user to rotate the orifice smoothly. This fine-tuning alters the leverage and spring seat pressure under real breathing simulation, helping you locate the perfect balance and airflow setting instantly.
Key Features & Specifications:
- Live Pressurised Adjustments: Allows full calibration of the second-stage orifice without having to turn off the gas supply or bleed the hoses.
