ARB tyre deflator

I have set the pressure and then used Loctite


Now thats a great idea David !

The ARB is a bit fiddly, but it lets out a heap of air in no time and to whatever pressure you wish. I fine tune the pressures with a nail on my keyring and a tyre gauge.

If it was 10 psi out I would be taking it back. 2 PSI or so out I could understand.

Most guages vary, and it is a constant variation, but as the right footprint tyre presure is a subjective thing I just set it where I think it is right. If the guage reads 18psi but is really 20psi who cares. I usually carry a spare guage or two anyway so I always have a good indication of what guage is reading correctly. I purchased a Michelin guage 30 years ago and that thing is still as accurate as the day I bought it and it is what I class as the master guage and thats what I measure accuracy against.

These were 3 different ARB tyre deflaters brought from our club members

The ARB's were reading 18psi was in fact 28 psi, no wonder I had trouble driving through soft sand in the Big Desert

A few months ago I was involved in a bulk buy of the ARB deflators. The gauges on 20 were with in 2 lbs of each other.

We must have got a bad batch.

I still think they are quicker than stuans

Hey Skippy, Forgive me if this sounds dumb.... but when you were using the ARB deflator thingo, were you allowing the gauge to "set" once you turned the knob to stop the outflow of air?

I was watching somebody do their tyres with one of these on the weekend and I said to him something like.... "strewth, how low are you letting them down?"....the gauge was showing about 15psi as he was deflating, but as soon as screwed up the knob to stop the air flow, it jumped back up to about 25psi....

Just wondering if the blokes were using it/them properly?

Hi Bill , I'm not sure what the 2 other guys done and I can't remember how i did it.
I'm sure i was told how to use it and thats what I did

But you could be right that would explain the 10psi differance

Skippy

My ARB deflater is a few psi out - just means you lower the pressure 3psi further to allow for it.

or, you may wish to consider a FERRET ...

I have one, & it's a well-made bit of gear, and works as advertised;-))
