The Aqualung 26mm yoke nut socket from Scuba Service Tools is a precision-machined, extra-thin-walled stainless steel tool designed for servicing Aqualung and select Apeks first-stage regulators, ensuring damage-free removal and installation. The tool features a 26mm slimline design with an integrated 8mm hex drive, optimized for tight clearances and safe operation up to 35 Nm.
How It Works:
- Place the first-stage regulator securely into a dedicated holding fixture or vice.
- Slide the extra-thin-walled 26mm socket over the regulator's yoke (INT) retaining nut.
- Insert an 8mm hex key (or a 3/8" / 5/16" hex key for imperial drive setups) into the top hex connection of the socket.
- Apply smooth, steady torque to unthread or tighten the yoke nut to the required specification.
- Limit application torque to a maximum tolerance of 35 Nm due to the reduced wall thickness of the tool.
Key Features & Specifications:
- Extra-Thin Wall Design: Specifically engineered to clear tight clearances around the regulator yoke nut where generic sockets cannot reach.
- Broad First-Stage Compatibility: Fits all standard Aqualung yoke (INT) first-stage regulators and the Apeks Flight yoke first-stage regulator.
- Dual Drive Compatibility: Features an integrated top 8mm hex connection that effortlessly interfaces with standard metric and imperial hex drives.
- Premium Construction: Precision-machined from heavy-duty, corrosion-resistant stainless steel for long workshop lifespans.
- Torque Optimized: Explicitly rated for controlled maintenance up to a maximum safety tolerance of 35 Nm.
