Argon or CO2 regulator with 2-300psi pressure output rather than flow?

[PhillipM]

Anyone know where I could get one of the above without having to donate a kidney?
Need a regulator that will give me a set output pressure (that's calibrated on the gauge as pressure, not flow) up to 200psi would do, more would be nice for some reserve, fitting for either CO2 or Argon, it's only for inflating so either will do.

Surely you are not going to use OUTPUT pressure of 2 to 300 psi!

 

[PhillipM]

Yes

It's for air springs, not tyres

Air springs ?????

 

[PhillipM]

Have you seen the air-spring rear dampers on most high end pushbikes these days? Like those, but a lot bigger.

 

[mike 109444]

You mean there not just for show..
Don't think you will get the pressure you want from CO2 so would have to be Argon (or mix)

Dunno what price you put on a kidney but you should be able to buy a good quality single stage reg for several flavours of gas/cylinder fittings with a delivery pressure of 0 - 40 bar (580ish psi) or higher for a bit over £100 + VAT. For example, https://www.weldequip.com/nitrogen-regulator.htm Rapidwelding do a range of high pressure regs alongside the more usual welding types too

I've got a nitrogen reg very similar to the one in Weldequips shop kicking around somewhere but it's eons out of date, i used to use it when rebuilding nitrogen charged dampers in the bicycle world

Similar thing hotrodder, these just use a large shaft and the air charge + oil height as an integral air spring as well.

 

[hotrodder]

Gotcha. If £130 - £170 is too spendy (i was assuming you'd only seen the posh £400 + multi stage examples) just had a thought... any Citroen specialists near you? I imagine most probably send tired spheres away on an exchange basis but same may do it in house and be willing to 'pump' yours up for a drink? Obviously no good if it's an ongoing concern/you want to be able fine tune things

 

[PhillipM]

Now there's an idea, I do usually sub our own dampers out to a shock firm down the road, but they've gone from a few quid a fill to £rape.99 - god know what they'd be like with air springs in so they take twice as much gas.
Did have someone fill up the 405's sphere's around here somewhere a few years back - will have to hunt through the reciepts.

I can fill em for you Phil, but I'm not exactly local.

You were last week, I was only around the corner, bit far now mind

However, saying that, I have a set here I'm doing for a mate of mind, who's about 30 minutes from yourself....
