Tire pressure release valves, Nakatanenga

Tire pressure relief valves - set of 4 pieces.

If you drive your 4x4 away from tar and asphalt or often regulate the tire pressure due to the load, the tire deflators from Nakatanenga could also be something for you.

You first set the desired pressure on the four drain valves (from 0.5 bar) and then screw them onto the tire valves. The deflators then do their job automatically and simultaneously on all four tires.

Setting the release valves: In principle, all you have to do is create the desired, reduced pressure on a tire and then the release valves are adjusted in pairs for the rear and front tires or for all four wheels as required. Tools are not necessary. The adjustable range is 0.5 to 3.8 bar.

Instructions

• Create the desired lower pressure (e.g. for off-road driving) in a tire and check it with a pressure gauge/pressure gauge.
• Bring the drain valve to the home position BEFORE screwing it onto the tire valve. To do this, simply turn both the adjusting screw and the locking ring on the drain valve downwards as far as they will go. The drain valve is now completely closed.
• Now screw the closed release valve onto the valve of the tire with the previously set low air pressure.
• Now slowly open the adjusting screw on the release valve until the air begins to escape from the tire. At the first hiss of air, the adjustment screw is immediately turned back a little until the escape stops.
• Now the desired pressure is set in the drain valve and the locking ring is turned up to the position of the adjusting screw. Be careful not to move the adjusting screw any more. Tighten the adjusting screw and locking ring against each other by hand at the stop.
• Repeat the process with the other valves, in pairs or on all four wheels as necessary.
• The valves are now ready for use. If necessary, simply screw it onto the tire valves and wait until no more air escapes. Depending on the setting, releasing the pressure usually takes a few minutes.

My opinion

No personal experience. Some people swear by it, but when I look at the handling, I prefer to use a conventional drainer or the quick drainer from ARB.

Addendum: I have now tested it myself. If you always want to release the air to the same pressure and you don't mind having to fiddle around (once) to set all four release valves to this pressure, it's ok.

This is too inflexible for me, since we adapt the pressure to the surface and don't always use the same pressure across the board.
