Hi Folks

Has anyone had any experience with them?

To set the pressure to what you want, use a bike tyre. It is much quicker!!!!!!!!!

Yep, have had a set for 8 years or thereabouts. If you do a lot of sand as is the case here in WA they are well worth it. A one person operation. You don't have to find a stick to/or poke something into the valve stem.
As you are aware you need to preset the deflation pressure, I set mine to 18psi so it allows it to go lower. Some locations require 10psi

I have 2 sets, i set at 18 and the other 28. As said above they work a treat if you do regular sand driving because you just screw them on and take them off when they have finished. Just make sure you set and test them to start with. I have found them to be totally reliable and take them on every trip.

Kind regards

PS Hope Santa delivered a compressor as well.

yeah me 2; same as Beatit.

One set at 15 psi for beach runs - these are dobbed with yellow acrylic paint by me over the lock ring. The others at 28 psi - they are with a white dob of over the lock ring so I can see if the adjustment has accidentally altered.

Here is a copy of an article I wrote for the 4Wheeling SA on-line magazine. I have left the pictures out.
zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

There’s lots of gimmicky things that tempt a four wheel driver to part with his cash.
But here’s one that may just be worth investigating – Staun Tyre Deflators. As the ad says, they will let you down. And for setting tyre pressures at a predetermined level, they work well. By adjusting a brass ring, and screwing the deflator onto the valve stem, they are the easy way to drop tyre pressures to increase traction.

Let’s imagine I’m at Robe and about to cruise through the Little Dip Conservation Park. I’ve got 3 mates on board, a few coldies, some fishing gear, and the cricket is on the radio. Having come off the blacktop, my tyres are at 36 psi.

In the past, my mates & I used to let tyres down the old way. With one person on each tyre, I would count slowly to 45 (out loud) & we would all in turn check the pressure, which experience told me would be close-ish to what I wanted. Then it was fiddle-faddle with the tyre gauge to get all four tyres to exactly what we desired – all up at least 15 minutes.

However, by screwing on the 4 Stuan valves, the tyres now emit a persistent hiss of air to settle at exactly 18psi. By the time I have screwed the last of the four valves on, the first tyre is deflated exactly to my preset pressure. It’s over, and it took less than five minutes.

So what I’ve saved is a heap of fuss and time. No more mucking about with small sticks/keys/screwdrivers to press the valve in to let air escape. No more do I need to check each tyre 4 or more times to get it exactly to that magic psi level. The Staun’s get you there in one motion.

It might be fun the first couple of times all jumping out to let the tyres down, but the novelty soon wears off. Remember, there are more important things to do – like opening beer! If you’re driving in different conditions, maybe it’s worth getting two sets of Staun’s with one set calibrated at 28 psi for dirt roads, and another at 15psi for sand.

Cheers

I've had my set for about 2 years. I found that I had to reset the pressure setting as all different ( all within 2 PSI) but I'm fussy. Work a treat, worth having in the glove box.

Always carry a set 2@18psi & 2@15Psi, have been a life saver and always borrowed on trips by others.

I agree, don't need two sets (expensive). Set two at your sand pressure and mark (colour code) them, set the other two at road pressure for use after you re-inflate your tyres back to hard surface pressure

Hi,

They are great. We use ours a lot as we do a lot of sand driving.

Stop at a nice shady spot.
Take out the deflators.
Take off the valve caps.
Watch heaps of 4wds fly past you too get to the barge quickly.
Fit the deflators.
Air will escape to a predetermined pressure.
Take the deflators off.
Fit the valve caps back on.
Drive along the churned up sand track that the 4wds previously rooted with there normal tyre pressures.
Bypass the stuck 4wd with normal tyre pressures .
Get onto barge knowing that you did the right thing.

Ive had a set for few yrs still in the packet LOL

I Still just remove the valve core, and have figured out how much air comes out in round 20 and 30 seconds, and work from there.

expensive for what they are. Would be unbeatable value for $20

Looks like its all been said... top peice of kit. If you do any sand driving, use them, and you'll never look back.

They are a waste of time and $70/80

Mine have rattled their settings loose inside their jacket, inside the centre console.

I don't use them any more. A stick works fine

I have heard this elsewhere too with the constantly havin to be reset, thats why I never bothered!

ARB or TJM Twig works wonders

as I said, if they were $20, they would be good value

I've got 2 sets; didn't pay for either of them....one was compliments of 4x4 Australia Mag for writing a 25 word ditty about why I wanted a set; the 2nd was for renewing my sub to 4WD Monthly a year or so ago.
I set them @ 18psi and 28psi and put a drop of super glue on the lock-nuts so they won't move unless I want them to!!!! ;-))))

They are well worth it. Set two at sand pressure, 2 at gravel.

Set them both up using a bike tyre instead of pumping the 4wd up and down until you get it right. Much quicker and easier. It works off pressure and 18 pound is 18 pound in whatever size tyre you are using.

Once set, a dob of superglue or loctite will fix it in place, and it will never need setting again.

A rela good piece of kit.

Once you've used them you'll never go back.

A good birthday gift, start putting out the hints now;-)

for w.a. veiwers theres a deflator called the ferret. no springs or little bits to rattle lose over time,no glueing bits together. it screws on to valve and you unscrew valve stem, lets tyres down 1psi/sec. can only do one tyre at a time but at about 10-20 sec. a tyre thats allright to me. oh did i mention there only $25 from ferret tools

Wouldnt a normal valve core remover that doubles as a valvecap for $3.00 for 4 at Big W do the same thing?

only if you think your good enough to catch the core as it flies past your ear. the ferret traps the core inside it so you can screw it back in.

I always use mine. A drop of light oil occasionally on the shaft ensures they work accuarately. Once set I have not had problems with collars working loose. I have two set at 20 and two at 30. I work down from there if needed.
