Re: TOY: automatic tire deflators

[Thom Singer <ntsqd@xxxxxxxxx>]

I like the ones I made. I bought 3 clip-on inflator chucks from Shlep
Boys and one of those self coiling air hoses. I have a T at one end of
the hose with a tank valve on the branch (Schrader stem on one end,
1/8" NPT on the other).
Then I got a over-pressure pop-off valve similar to those used on air
compressors. Mine was free, but McMaster carries them in a variety of
different pressure thresholds. Mine is rated @ 20 lbs, but experience
with it has shown it to stop at 19 psi by my Blue Point Gauge. Don't
really care what the number so long as it gives me tire pressures that
work and is consistant.
My intent with the self coiling hose is to equalize the air pressure
across the lockers. I've found that my truck is sensitive to as little
as 3 psi difference. At one point I drilled the side of the T and
installed a fairly high quality gauge. Mistake I made was either using
too low a max pressure gauge or using shop air pressure to fill the
tires. The gauge has been rendered useless.
