**IMPORTANT**  The US company from whom we sourced these kits has recently gone out of business and we do not have stock to fulfil further orders at present.  We are seeking to source components ourselves to assemble additional kits but this may take some time.  Please send us an email via our contact page if you are interested in us letting you know when these become available. Thank you.

Just some of the features: 

• Hands free tyre inflation that will set all of your tyres to the same pressure. 
• Works with any air supply you would normally use to air up a single tyre. 
• Many options such as a system to tie into on board air compressor. 
• Liquid filled stainless steel gauge options. 
• Many mounting systems available. 
• Polyurethane tubing installs so that it never touches any part of the vehicle. 
• Manifold and control station stays put on the vehicle, the only thing you deal with is the very small and color coordinated whips that quick disconnect to the tyre and the manifold at normally closed connection points. 
• System can be fully hidden on the vehicle or proudly displayed, 
• it is universal and can be adapted to any vehicle with multiple tyres. 
• Systems available for vehicles up to 16 tyres at one central control. 

 

 

• Maximum Working Pressure: 145 PSI 
• Maximum Operating Temperature: 160°F or 71°C 
• Net Weight 4.8 lbs.

 

Q. What vehicles does 2Way Air fit?

A. 2Way Air was engineered to be universal in application and modular in design. We offer a 4 tyre Master Kit that fits anything with four tyres–cars, trucks, tandem axle trailers, quads, you name it. Our 6 tyre master kit works on dually trucks, motorhomes and triple-axle trailers. If youve got more tyres than that (such as a tag axle motorhome), we offer 8 and 10 tyre kits that you add to our 6 tyre master kit.

Q. What do 2Way Air kits include?

A. Our master kits include everything you need for installation, including 3/8-inch and ¼-inch polyurethane manifold tubing, push-to-connect fittings, tyre whip quick disconnects, tyre pressure set point valve, tubing cutter and suggested routing diagram.

Q. How difficult is installation?

A. The most difficult part of the installation is determining where you want to mount the connection point valves, and how you want to route the manifold tubing. Once this is determined, installation is actually pretty straightforward and usually takes between 2-4 hours depending on the vehicle and the installers experience/skill level.

Q. How do I inflate my tyres?

A. 2Way Air consists of a control panel with two central inflation points (Schrader valves), a manual control valve, and manifold tubing that Ts off to an individual connection point valves (CPVs) near each tyre. Quick disconnect “whips” are attached to the tyre valves and CPVs, and youre ready to introduce air to the system. Once the tyre pressure set point valve (TPSV) releases excess pressure, simply turn off your air source, disconnect the whips, and youre done. 2Way Air is designed to accept any air source youd normally use to inflate your tyres, including a portable air compressor, on-board air system, air tank, CO2 tank, gas station air hose, etc. In fact, the system has been designed to accept up to three air sources at the same time, such as on-board air, a shop air hose and a CO2 tank, for example.

Q. How do I deflate my tyres?

A. Simply connect the whips and open the manual control valve, and all tyres will begin deflating at the same time. You can monitor pressure by using a tyre pressure gauge on one of the central inflation points, or with one of our available liquid-filled gauge kits.

Q. How long does it take to adjust tyre pressure with 2Way Air? Is it that much faster than traditional methods?

A. Once the system is installed, all the user needs to do is connect the whips at each tyre and connection point valve. These connections are patent-pending, quick connect/disconnect fittings that just click into place–figure it takes 10 seconds or less to connect to each tyre/connection point valve. From there, you simply inflate all tyres at once using any method you would normally use to inflate one tyre. How quickly the tyres inflate depends entirely on your air source (or sources). Deflating is simply a matter of attaching the whips and opening the control valve. In any case, inflating or deflating literally takes a fraction of the time of traditional methods.

Q. How does the tyre pressure set point valve (TPSV) work?

A. The TPSV releases excess pressure during inflation. You simply adjust it to your maximum desired inflation pressure, and when air is introduced to the 2Way Air system, the valve will open with a distinct sound to let you know that the desired pressure has been reached.  The beauty of the TPSV is that you dont need a tyre pressure gauge, and if you have an on-board air system, you can air up the tyres while doing other tasks. To see how the TPSV is adjusted, see our installation videos page.

Q. What if I dont want to inflate or deflate all tyres to the same pressure?

A. We realize that many 2Way Air users may not want to inflate all tyres to the same pressure, such as RV owners who may run more pressure in the rear tyres. In this instance, you would simply adjust the TPSV to the lower of the two pressures during initial installation. Connect the whips and begin inflating the tyres; when the TPSV pops off, simply disconnect the front whips and continue to inflate to the rear tyre pressure. Alternately, and even easier, tie a secondary manual control valve and TPSV into the 2Way Air system, inflate until the front TPSV pops off, disconnect the whips and continue to inflate until the rear TPSV pops off.

Q. What if one tyre is lower or higher than the others?

A. Once the whips are connected at each tyre and connection point valve, all tyres are effectively tied together through the central manifold system–so once you begin inflating, all tyres will inflate to the same pressure.

Q. What if I only want to adjust the pressure in one tyre?

A. Just connect the whip to that one tyre and introduce air to the system. The system will balance the pressure in that tyre to the others, and the TPSV will pop off when the desired pressure has been reached.

Q. What if I have a truck and a trailer or a motorhome and a towed car and I want 2Way Air on both. Is that possible?

A. You bet. Simply purchase the appropriate master kits, one for the towing vehicle, one for the towed vehicle. You can even tie the two systems together with our jumper hose kit and inflate all the tyres on both vehicles at the same time!

Q. What if the manifold tubing gets damaged? Will air leak from the system? 

A. No. The 2Way Air system is “on demand” in that it can only inflate or deflate tyres when the whips are attached, which effectively ties the tyres into the system. 

Q. Is the system easy to repair if it gets damaged?

A. Yes. In fact, 2Way Air was designed for extreme off-road environments, so it was designed to be repaired on the trail. If a section of tubing were to become damaged, you simply pull it out of its push to connect fittings (by pulling back on the fittings collar), use the tubing cutter to cut a new section, and push it back into the fittings. Its easy and fool proof.

Q. Why is polyurethane used for the manifold tubing? Why not nylon like other air systems use?

A. Nylon is only required in systems that carry air pressure, like air suspension. 2Way Air is an on-demand system, and the only time it is pressurized is when the whips are attached and the vehicle(s) is stationary. Polyurethane is much easier to cut, bend and work with, and wont kink or crack like nylon or other types of tubing. Finally, our tubing is food grade, meaning it is made to a much higher standard than industrial tubing. Its also rated for up to 145 PSI, so its safe to use on trucks, motorhomes, etc.
