NAUTEC Proline 300 bar M25x2 Nitrox Valve

NAUTEC Proline 300 bar M25x2 Nitrox Valve

NAUTEC has designed this 300 bar Nitrox valve, part of its Proline professional range, to be fitted to diving cylinders intended for oxygen-enriched (O₂) mixtures.

Compliant with the European standard EN 144-3, with its M26x2 outlet thread specifically designed for Nitrox/O₂, it prevents any accidental connection of a standard compressed air regulator.

Its forged brass body features a high-quality chrome finish. It is fitted with an ergonomic Proline handle made from soft elastomer, providing a secure grip.

Its internal mechanism, featuring a horizontal flat valve developed by Nautec, minimises friction and allows for smooth, gradual opening and closing without placing excessive strain on the seal. Finally, its integrated dip tube protects the mechanism from impurities and residual moisture at the bottom of the cylinder.
