Mares 25mm yoke nut socket precision machined from stainless steel with an 8mm hex connection.

The Mares 25mm yoke nut socket is a professional-grade workshop tool designed specifically for servicing scuba regulators. Engineering constraints on Mares' first stages mean that a standard off-the-shelf socket simply will not fit. This specialized socket features extra-thin outer walls, allowing it to slip effortlessly into the tight clearances of Mares Yoke International (INT) first-stage regulators. Precision CNC-machined from high-tensile stainless steel, this tool ensures clean engagement with the yoke nut, reducing the risk of slippage and preserving the finish of your equipment. It is an indispensable asset for commercial dive centres and serious dive technicians working on Mares first stages.

How It Works:

To use this tool, slide the extra-thin-walled 25mm socket over the yoke nut on your Mares first stage. At the top of the socket, insert an 8mm long hex key (or a 3/8" / 5/16" hex key for imperial users) attached to your torque wrench or breaker bar. Apply a smooth, even force to loosen or tighten the nut. Due to the ultra-thin wall design required to clear the regulator body, a maximum torque tolerance of 35 Nm is highly recommended. For seized or overly tight nuts requiring more force, it is advised to use universal yoke nut pliers instead.

Key Features & Specifications:

Ultra-Thin Wall Profile: Specially engineered with an extra-narrow outer diameter to fit perfectly inside tight Mares regulator bodies where standard sockets fail.
Dual Hex Compatibility: Designed with a built-in 8mm hex top connection that seamlessly accommodates an 8mm long hex key, as well as 3/8" or 5/16" hex keys for international users.
Premium Material: Precision-machined from heavy-duty, corrosion-resistant stainless steel for long-lasting workshop durability.
Torque Rating: Maximum recommended operational torque threshold of 35 Nm to preserve the integrity of the thin-walled socket architecture.
Broad Compatibility: Fits a wide range of Mares INT first-stage models, supporting official Mares part numbers: 46182205, 46186241, 184063, 46185212, 46186205, 46201100, and more.
