Mares CWD tool for 82X first stage regulator precision machined from stainless steel with cross handle.

The Mares CWD tool for 82X first-stage regulator is a highly specialized, workshop-grade instrument engineered specifically for professional dive technicians overhauling Mares 82X first stages equipped with a Cold Water Dry (CWD) kit. This dedicated tool is designed to safely open and close the specialized top ring of the CWD dry kit, a critical step required to access and replace the internal black environmental diaphragm during routine annual servicing.

Precision-machined from premium stainless steel, this tool ensures an exact, slip-free interface with the regulator's external components. Attempting to loosen or tighten the CWD retainer ring with generic workshop tools or pliers can easily slip, resulting in severe cosmetic scratching, distortion of the metal, or unequal pressure on the internal sealing diaphragm. This professional instrument provides the perfect mechanical fit, allowing scuba service centres and independent technicians to execute complex cold-water kit maintenance swiftly while maintaining factory-level precision and sealing integrity.

How It Works:

Engagement: Align and lower the tool into the circular opening on the top section of the Mares 82X CWD dry kit body, ensuring the two precision-curved keys slide perfectly into the corresponding curved slits on the retainer ring.
Disassembly: Utilise the integrated stainless steel cross-grip to smoothly turn and unscrew the top ring by hand, breaking the factory seal to lift out the old environmental diaphragm.
Reassembly: After installing the replacement factory black diaphragm, thread the top ring back into position. Use the tool to guide and tighten the ring down smoothly, ensuring uniform torque distribution for a perfectly gas-tight, dry-chamber environmental seal.

Key Features & Specifications:

Tailored 82X Engineering: Custom-dimensioned specifically to match the unique curved slits and circular dimensions of the Mares 82X CWD top ring.
Premium Stainless Steel Construction: Precision-machined entirely from robust, high-grade stainless steel to deliver lifetime workshop durability and complete resistance to corrosion.
Integrated Stainless Steel Grip: Features an ergonomic, built-in cross-handle design providing maximum hand comfort and precise manual torque control.
Anti-Slip Protection: Designed to fit perfectly flush within the CWD ring profile, eliminating the risk of tool slippage, parts damage, or uneven seal seat alignment.
