Screw-on fitting for tyre valves

Post by **-Scott-** » Thu Sep 16, 2004 3:42 pm

Hi All

I'm looking for a screw-on fitting for the end of my air hose, to screw onto the tyre valve. I was in TJM the other day, and most of their pumps all had very similar fittings, like I want, but they don't sell the fitting as a spare - I'd have to spend $50 buying replacement hose with gauge!

I've tried all the usual Auto chains, some tool shops and some specialist hose shops - nobody knows where to buy the screw-on fittings.

Anybody have any suggestions?

Thanks,

Scott

Pirtek? Top$$ though..

why do you want a screw on fitting over the clip on one like servos?

The existing hose (standard ARB supplied thing) has a clip-on fitting, which doesn't always want to seal onto the valve well (the Big Red I saw in TJM uses the same fitting.) Given that the ARB compressor is a little slow :roll:

holding it on the valve while I'm pumping up the tyres is a PITA.

I've bought bits to put a variable pressure cut-out on the air line, so I can set the pressure I want, hook up the hose, then sit back and wait for the pump to cut out. :armsup:

If the fitting on the valve is leaking it'll only take longer.

A few places have a more substantial clip-on tyre "chuck" but I'd prefer one of the screw-on fittings if I can find one.

Cheers,

Scott

I have the same problem with my ARB compressor and fittings. I find that the fitting will leak if the hose is tightish and pulling slightly on an angle. If the hose has no sideways pressure on it i find it is OK.

What is the variable pressure connection you have? How much? I guess you can get it from a 'hose and fittings' shop. I have been thinking of getting a stop type fitting for the end of the hose so the compressor will reach pressure and therefore stop between tyres. I was not sure if the hose would cope with the full pressure of 100psi or whatever the compressor cuts out at. Any thoughts?

Buy a set of metal valve extensions and fit to end of hose.
Dont know how youde turn the lot to tighten them though?

My ARB end works well. I rubbed a small file on the tapered locking clip just inside the chuck to sharpen locking tooth and it bites threads alot better. It had worn a bit squareish from being pushed on a lot.

I'm looking for a new way of attaching my Maxair onto the valves too- because it's such a bl**dy tight fit it's near impossible to lock it on..... It's the type where you have to operate a little lever 90 degrees and that squashes a rubber piece inside which grips the valve.

It's near impossible to move the lever enough to lock it on using two hands to do it. :roll:

Anyone want to swap? :lol:

Yep, that's the problem I have...

It's actually an electronic switch which I obtained at an excellent price from my friendly pneumatics supplier. It's rated to IP65 (67?) but I'm a little unsure how it will react to life under the bonnet. :?:

Theoretically I can dial up the pressure I want, and use this to switch a solenoid to isolate the tyre hose. Then the tank can pump up as per normal and cut-out the compressor, so the hose should only be carrying tyre pressure. But hose and fittings are all rated to 8 bar (120psi) or more.

I've got a small ball valve on the tank outlet to isolate all this when I'm not pumping up tyres, and another on the end of the hose, to keep pressure in the hose while moving between tyres. It's all good in theory, but I've gotta get it all connected first, then see if it all copes with living under the bonnet.

Cheers,

Scott

Sounds pretty good. My compressor is the ARB toolbox one with the pressure switch. So I won't have to worry about under bonnet stuff.

try kmart etc and look for a cheap compressor with the fitting you want then just cut it off and fit to your hose.
wouldnt screw on fitting lose pressure when you are taking it off ?

Jamec pem make a clip on fitting that when not on a valve stops the air flow and is very well made (for tire shop use) and clips on well and doesn't leak

Where can I buy one?

Have a look at this catalogue- page 15 has got some clip on tyre valve fittings.

The fitting in the bottom LH corner is the clip-on I found in Glenfords and a few others. If I can't find a screw-on I think I'll go with that.

Cheers,

I also use the 03-0410 s on my endless air and shop air. Works good

Scott, I had the same issue with the crappy ARB fitting.
I fitted one of the Jamec Pem ones to the air up hose and never had a problem since.
However when I got the Simex's with new rims they had the tyre tube stem protectors (like a Chinamans cap welded over the stem) the Jamec one was a pain to use as there wasn't enough room any more.
I tried the lever one (where it compresses the rubber gland over the tube stem) but this didn't work much better (you can buy these at Autobahn).
Then I cut a screw on type version that I had on an old compressor and grafted that to the air up hose now it works fine. I've never seen these sold seperatley though. But if you don't have the tube stem protectors on your rims the Jamec one is perfect.

Scott, I have the one in the bottom left corner (03-410) and have had it for years. Works great, always clips on tight, seals off when not connected.
