NAUTEC VALVES
Precision engineered for divers who depend on reliability, efficiency and strength.
232 and 300 bar
Ready for pure oxygen. Every valve shipped 100% oxygen-clean - certified for Air, Nitrox, Trimix and O₂.
Double Wheel Knob
Full metal core. Precise control and dexterity at any depth, any environment, with or without gloves. Smooth linear performance even at full tank pressure.
Silicon Brass Alloy
Military-grade. Lead-free. Harder, stronger and more corrosion resistant than conventional brass valves. Tighter tolerances means longer life.
Tested to 675 bar
Solid body built to absorb impact. NATO approved. Certified to the highest standards by BAM Berlin: drop impact and oxygen pressure surge test to 360 bar (60°C).
80% More Torque
Superior robust engineering.. Hexagonal spindle into a hexagon seat allows for far greater torque than conventional ‘slotted spade’ design and resists flex under stress.
HP and HT Seat
High performance thermoplastic seat replacing conventional nylon. 2000 hand cycle endurance test with zero deformation. Consistent sealing under extreme pressure and temperature, cycle after cycle.

Configure Your Nautec Valve
Seven choices. One valve — yours.
Select your tank neck standard first: M25x2 for European cylinders, 3/4″ NPSM for US threads. Get this wrong, and nothing else matters. Then dial in gas type, pressure rating, outlet size, left or right orientation, finish and knob. Every combination ships 100 % oxygen-clean.
