I'm not really sure what to call this but it works extremely well for airing down on the trail

Inflating or deflating tires can be tricky when you're trying to get equal pressure in both front or back tires.
Even if you run different pressures in the front compared to the rear, you ideally want the 2 front tires being the exact same pressure and you want the rear two being the exact same pressure.

With the above in mind, here's a tool you can create that will solve those problems.
This is also a great tool for airing down for the trail. It works quickly and does two tires at a time.

Parts needed:

1. A roll of pipe thread seal tape : $0.49 at Harbor Freight
2. 3/8" X 8' - 15' Air hose with 1/4" male ends (At least this length) : $3.99 at Harbor Freight
3. 1/4" NPT Coupler-cross. (A 4 way brass connector) : $$2.89 at Harbor Freight
4. 3/8" Barb fitting 1/4" male ends with clamp (2 of them) : $1.89 each at Harbor Freight
5. Tire chuck 1/4" female end with clip (2 of them) : $2.99 each at Harbor Freight
6. Tire guage : $? Had it already
7. 1/8" X 1/4" NPT brass connector : $1.88 at Auto Zone
8. 1/4" full port ball valve : $7.96 at Home Depot

Total: $26.70 not counting the cheap air guage

All the parts


Open the hose up and cut it where you would like the deflator/inflator device.
Once cut, insert the 3/8" hose barb and tighten down the clamp.


Now grab your air guage and see if the tip unscrews. Mine did and you can see from this pic it has a 1/8" threads under it. We need it to be 1/4" so take your 1/8" - 1/4" adapter and screw it onto the tire guage.
Remember to use thread tape on all threads.


Screw the guage and the full port ball valve into the 1/4" 4 way connector.
Remember to use the thread tape on all threads.


Screw the air hoses into each side of the 4 way connector.
Remember to use the thread tape on all threads.


Screw the tire chucks on the other side of the hose.
The clips on the chucks actually hold the chucks in place for you.
Remember to use thread tape on all threads.



Now go out connect it to your tires and check for leaks. That's it you're all done!


Once both tires are hooked up, the two tires will equallize their pressures. You can see this in the guage. To drop the pressure, turn the red valve on the valve (seen in red on the device). Air will release. Close the valve and check the air pressure again. If you need to let more out, open the valve again. It's as easy as that



The only thing I forgot to mention is that if you have an air compressor, you can add a male connector under the ball valve. Then all you would have to do is connect the air compressor hose and fill both tires at the same time.
It will always keep the pressure equal between the two tires.

Enjoy

Slick! I like that.

Very nice.

oh now that is ingenious.

looks as if it would be possible to get some longer hoses and hook a 2nd on on the bottom of the first where the release valve is and put the release valvue below that one which would give you all 4 tires at once...

atomicmecha

oh, and i don't know if its all of them or not, but the Pepboys here have those tire gauges for $0.99.

Yes you could easily add another section and do all 4 tires at once.
I like it two at a time because right now the whole thing is nice and compact when the hose is wound up. But 4 would be great also

You should build these and sell em. I'm sure a bunch of people who don't feel like gathering up the parts would snatch em up quick.

I really like this idea. Simple and effective and ....cheap.

VBS4

hahahahaha, yep I guess I could put some together for people, tack on a couple dollars for my gas time.
I'm sure now that you said that, a certain vendor will start selling them, like I've seen them do with a couple write-ups....lol


And it actually is. It's so simple to use and airs them down quickly and evenly

An ingenious product, to be certain! Good job on the build, V!
