Mares MR12 guide bushing tool with acetal push rod for scuba regulator first stage servicing.

The Mares MR12 guide bushing tool is an essential piece of specialised scuba technician equipment designed for the professional maintenance and overhaul of Mares MR12 first-stage regulators. Precision-engineered to streamline your regulator servicing, this high-quality tool ensures the safe, accurate, and seamless installation of small internal components located directly on top of the main spring within the first stage body.

Using this professional-grade guide tool eliminates the risk of component misalignment, friction damage, or cross-threading during assembly. It provides scuba service centres and dive technicians with a reliable, efficient workshop solution that drastically reduces service times while maintaining factory-level assembly precision.

How It Works:

Alignment: The guide bushing tool is securely inserted into the first-stage body of the Mares MR12 regulator to serve as a precise channel.
Component Placement: Small internal parts are loaded through the guide sleeve, allowing them to smoothly slide into their designated factory positions on top of the spring without binding or tilting.
Securing the Assembly: Once the internal components are perfectly seated, the included custom-fitted push rod is utilised to slide and lock the internal retaining circlip firmly into its groove, finalising the installation securely.
