MTX RC STAGE3

First Stage

Available in yoke or DIN configuration. Suitable for cold water use (below 10°C / 50°F). Over-balanced diaphragm design increases medium-pressure gas delivery rate as depth increases for improved performance at depth.

• Over-moulded endcap and environmental diaphragm for improved durability.
• Forged first-stage body with heat-exchanging ribs and a ribbed diaphragm clamp for maximum thermal performance in cold water.
• Angled high-pressure ports for optimal hose routing and transmitter fitting.
• Forged rotating turret with medium-pressure ports arranged in parallel for improved hose orientation.
• 5th 3/8" UNF medium-pressure port includes a protective bumper when not in use.
• Double-swivel hose for greater freedom of movement.
• Tested for octopus use to EN250A cold-water standard.
• Nitrox/oxygen compatible up to 40% O₂ (outside the EU). Within the EU, oxygen mixes above 21% must use an M26 connection.

Second Stage

High-performance, pneumatically balanced, lever-operated poppet valve with a large, self-flushing purge button and a patented heat exchanger that reduces valve cooling by dissipating gas-expansion cold and drawing in ambient warmth.

• Front cover with over-moulded elastomer and a formed chrome-plated brass plate for improved durability.
• Large protective elastomer bumpers on top and sides to protect against impacts and scratches.
• Reversible configuration for left- or right-hand gas supply.
• Comfo-bite mouthpiece for comfortable fit.
• Flexible nylon-braided hose offers improved cold-water performance compared with traditional rubber hose.
