MTX-RC Dive Regulator

Overview:
The Apeks MTX-RC dive regulator is engineered for divers who demand absolute reliability in the most extreme environments. Designed using rugged military-grade engineering, the MTX-RC delivers exceptional durability combined with the smooth breathing performance Apeks regulators are known for.

Built to perform in extreme cold water, deep diving, and demanding technical conditions, this regulator provides full diver control with adjustable breathing resistance and a robust construction designed to prevent freezing and free-flows.

First Stage Features:

• Satin chrome plated brass body with heat-exchange ribs for maximum thermal performance.

• Innovative over-moulded first stage endcap and environmental diaphragm to reduce ice formation and protect against impacts.

• Ribbed diaphragm clamp enhances heat exchange in cold water environments.

• Over-balanced diaphragm design improves breathing performance at depth.

• 5 medium pressure ports, with 4 mounted on a rotating turret for optimal hose routing.

• 2 angled high pressure ports for gauges or transmitters.

• Durable one-piece forged body construction.

• Easy-to-grip DIN or over-moulded Yoke handwheel for one-hand operation.

• Tested to EN250A standard for Octopus use to 60 meters in cold water.

• Nitrox compatible up to 40% O₂ (EU regulations apply above 21% O₂).

• Available in DIN, Yoke, and M26 connections.

Second Stage Features:

• Pneumatically balanced second stage for smooth and effortless breathing.

• Protective bumpers shield the second stage from impacts and scratches.

• Large breathing effort adjuster for easy control while wearing gloves.

• Ergonomic Venturi lever for airflow control.

• Large purge button for quick regulator clearing.

• Reversible second stage for left or right hose configuration.
