The Mares high-pressure seat tool is an essential piece of workshop equipment engineered specifically for professional scuba technicians overhauling Mares diaphragm first-stage regulators. This specialized tool provides a safe, highly controlled solution for the precise installation of high-pressure (HP) valve seats, making it a critical asset for servicing popular Mares models, including the MR12, MR22, and MR32.

Precision-machined from premium white acetal, this non-marring tool eliminates the risk of scratching or gouging the delicate, mirror-polished internal metal surfaces of the first-stage body. Unlike generic metal punches or makeshift instruments that can easily cause microscopic scoring on critical sealing areas, this high-density acetal tool ensures that the new HP seat slides straight and seats perfectly without tilt or friction damage. It is an indispensable addition to any professional dive centre or commercial repair workshop aiming to maintain factory-level assembly standards.

How It Works:

Alignment: During the reassembly of the Mares diaphragm first stage, position the new factory high-pressure seat squarely into the entry chamber of the regulator body.
Seating: Place the custom-contoured tip of the white acetal tool directly against the back of the seat.
Installation: Apply smooth, uniform manual pressure down the tool handle to guide and push the HP seat straight into its designated factory position until it locks securely into place.

Key Features & Specifications:

Targeted Model Compatibility: Custom-built specifically for installing high-pressure valve seats in Mares diaphragm first stages (such as MR12, MR22, and MR32).
Premium White Acetal Construction: Precision-machined entirely from robust white acetal to guarantee structural integrity while fully protecting brass and chrome surfaces.
Component-Safe Design: Engineered to eliminate internal abrasions and scratches on sensitive, gas-tight internal regulator components.
Optimised Workflow: Enhances workshop speed and turnaround times by ensuring exact, error-free component alignment on the first attempt.
