staun deflators

[ajsr]

hey all
is it just my set or are these things the most inacurate things out??
my lovely wife gave me a set of the 0 - 10 psi jobs for my birthday,
now I set them all at 5 psi but when I pump the tyres to say 15 psi they seem to stop anywhere between 7 and 4 psi and this is without moving a thing on them adjustment wise.
there is one of the four that will cut off at 5-6 psi and I'll cope with that but the other three are within 3-4psi of being the correct pressure each time. That would be ok if I was stopping at say 18 - 20 psi but Im in a zook on 34's so a couple of psi is heaps and I like to run it at between 3 and 6 psi tops

I tried the same one 4 times without touching a thing adjustment wise and this is what i got-
1st time 4 psi
2nd time 7.5 psi
3rd time 5 psi
4th time 7 psi
now these are brand new and suggestions
cheers andrew

Travelling over corrugated dirt roads, I used mine for the first time last week, I used the preset 18psi deflators and worked well.

How accurate is your tyre guage? I have 2 pencil guages that give different readings, and my dial guage also gives me a different pressure, my air compresser reads 5psi higher than it should, Usually I just go for the average is why I like to waited to get to a servo. I aired up at the servo, all tyres were exactly the same pressure before inflating.

When I was discussing the deflators with another guy, he asked if I had trouble with accurate PSI. Which sounds like the same issue your having.

I was thinking of setting each pair with different pressure's, put a drop of loctite on the thread, so I cant accidently change the when you screw them onto the valve. Use an engraver to write what psi each one is.

throw them to the shitroom... Just suffered from the same shit with a borrowed set on Fraser.. They said pressures were <20psi, then checked with pressure gauge, 35+ psi

Theres a reason they were free with crap mthly.

[brendan_h]

i never bother to set mine i just put them on and when they stop get the gauge out and deflate the rest to whatever

[GUEEY]

They are Shit !!!!!!!

I persisted with thse heaps of shit for two years.
I would set them up on my spare.
All to stop at 18 PSI.
When i would use them offroading i would have 2 of my 4 tyres air down below 12-14 pound.
Then my mates would have to wait for me to blow them up again.
I now use ARBs EZY Deflator
Yes i can only do 1 tyre at a time, but it is still faster than f@$king around with stuans that are not accurate.

yep the same $50 digital guage each time so its not that.
Im going to pull one apart and check the torerances/shit inside etc maybe its that.
If they advertised that they will get you to within 25 - 30 % of your preset pressure fine but they call these thing accurate!!!!
within 3-psi up or down from your desired pressure on a 0 -10 psi unit is a little large in tolerance for my liking

[bogged]

Then my mates would have to wait for me to blow them up again.
I now use ARBs EZY Deflator.

I use a valve core remover now.. count to 20 seconds, then refit core, and its usually not far off 18-20psi.. then use an ARB Twig off the ground to do the rest.

[ajsr]

lol thats how I had been doing it too . those arb twiggs are the shit
when the missus gave me these I WAS stocked but not for long.

[-Scott-]

At the end of the day, it's a simple mechanical device which relies on fine tolerances, and won't be terribly accurate.

Sometimes, I need to pull the plunger to get them to start - I also try to track how long they've been deflating, and sometimes I'll stop them & check.

If I was starting again, I'd get the ARB device - but the Stauns work well enough for the number of times I use them, so I'm not about to change.

[Dodgy Dave]

I tried removing the core on the beach, but it escaped my fingers and I had to start again.

Maybe set them 2 psi higher than you expect and "ARB twig" it from there.

[mhgill]

i have found that genuine stauns are pretty good, the copys are rubbish....

[80's_delirious]

I was going to get a set of Stauns, but there has been a few threads on here with the same complaints, every thread had guys saying they ditched them in favour of the EZ Deflator. I got myself one of them, cheaper than stauns, fast and easy to use, accurate as far as I can tell, and you have control over when to stop deflation. Just push it in to check the pressure, pull it back to let more air out.
The problem with pulling the core out is they can go flying if not careful. I lost one when I was distracted and didnt screw my EZ deflator back in properly, it flew out and got lost in the twigs on the ground, I had to pull the valve core out of my spare.

[SIM79]

Get a ferret, got mine 3 years ago for around $20, deflates very fast and its impossible to loose a core.



[QUOTE=mickyd555;300988]I have a set of staun deflators, they are like brand new. I used them a couple times but they never dropped tyres to the same pressures. I would not buy them ever.

I havnt used a ferret but if the BIG GQ likes his it must be good, he wouldnt talk it up if it wasnt.[/QUOTE]

[QUOTE=BIG GQ;301024]Sold my Staun's within a week of owning "The Ferret"[/QUOTE]

[QUOTE=BIG GQ;301026]Staun's are slow mate. You could individually do all four tyres (from say 40psi to 15psi) with the ferret quicker than you could walk around screw your four stauns on, wait for them to deflate at snails pace then unscrew them all
[/QUOTE]

[Gwagensteve]

I have two sets and they haven't been anywhere near my tyres since I got an ARB deflator.

Slow, inaccurate and fiddly, and useless if you like to experiment with pressures.

Hi all...Give them a good spray with a silicon spray,that will make them better.If dead accuracy is what your after,set them a bit higher and do manually with a quality guage.

I dont know how anyone can say they are slow,I screw my four in and just drive off on the beach to my fishing spot.When i get to my spot i unscrew them.No waiting what so ever.

[SIMMO84]

I love mine but im not that worried about how precise the pressures are. I just let them go until the trye gets "wobbly"when you hit it, finish my beer and hit the tracks............ with another beer.

So in reality you have no idea how fast/slow/accurate they are.. You fit them and drive off..... with tyres at full pressure.

[PJ.zook]

Yeh they are a piece of crap product, theyre just too innacurate. Thats why i sold mine. The EZ Deflators are great.

[Jeeps]

I use them and by the time i screw all four on, disconect my swaybar disco's, disconnect my mudflaps and manually readuce the pressure in my coil airbags the stauns are done with time to spare. I go down to about 15psi and they're usually accurate within 1-2 psi. Because i have to disco all my other stuff the stauns are probably faster for my situation. However at the beach where i don't disco anything then the ezy would be faster.

cheers

[mhgill]

I'm going from stauns to Ezydeflator so I can vary my pressures to suit the terrain.

I don't get this. Why is drink/driving acceptable on tracks, when it's not on the road? Your judgment is impaired just the same.

[SIMMO84]

You can do heaps harder stuff when your drunk. Nah seriously its all about getting out and relaxing, most of the time if your offroad you cant drink at all due to the bumps.

[mhgill]

If its private property I dont see a problem with a beer or two, I dont mean getting smashed, but sometimes you need a bit of bravery gravy for the harder tracks.

/Back on topic.

i got my stauns for free from the same mag that most people woulda got them. never used them on my car, as i had bought an ezydeflator already and figured the stuans could be a 'spare'.

first time i used the ezy, i chucked the stauns to a mate. in the time it took him to walk around his car and put them on, id dumped on of my tyres down to 16psi and was onto my 2nd. by the time his tyres were finnished, i had already given my exy to another mate so he could use it to check his pressures coz his ARB twig didnt come with a guage.

when we got back off the beach and went to inflate tyres, mine were all within .5psi of the 16psi i had set them at (which accounts quite nicely for any minor changes in internal heat, given that the tyres were warm when the air was taken out). my mates tyres ranged between 12 and 25 psi!!! (stuans were set for 18psi) even with huge changes in internal tyre temp, they should not be that far from 18psi, nor over that large a range.



since then, the stauns have not left my glovebox. they MIGHT come out if i forget or loose my ezydeflator, but the ARB twig will likely get the callup first. they will more likely come out if i have a mate who has really pissed me off needs to use them

[43som]

i've gotten stauns through work, and they work well. but i have only kept them at 18psi.
Have you contacted staun for advice on using them, last time i heard they didn't reckomend deflating below 18psi. which is were the comment of mechanical variance comes into it.

we're happy as larry with ours. we put them on then by the time the last one goes on the first one is done, don't drive with them on, as they could get ripped off.
I did however notice that they need to be put on but the stub, i turned mine on the adjustment peice, i think it moved a bit.

the set i have is for a finished pressure between 0 ans 10 psi (ie you cant set them to 18 psi they come preset at 7psi )so they only have 10psi variance.
to me a finished variance from set pressure of 4 psi in a product that only has a 10 psi scope is bullshit.
anyway as it turns out I removed a small amount of material from the inside tolerance uning a little 1200 wet/dry paper and then polished the inside and amazeingly they stop within 1 psi everytime now.
a quality made product my arse but they work now.

[Drift Technician]

Mate had a set of these brand new genuine ones bought from store, could not for the life of us get them to work properly no matter what we did.

Sold them and bought a "Bushranger" deflator (ARB copy and half the price) and haven't looked back since.

Hi all...Bogged,How could i not have an idea if i own a set.Ive probably had them for about 8years now.Ive never sat around timeing how long they take to down them to 16psi,but i would say it takes no longer than 5 minutes for 4 tyres.Accuracy is within 3 psi between the 4,thats plenty for me.When i air up i check the psi to see if they are still working ok.If i was going to drop psi and do some big klm ofcourse i would get them spot on.Yep,screw them in and drive off,to easy.Give them a blast with silicon spray every now and then and they work pretty good.
