Removing out valve from regulator

[welshy1812]

Hi all,

Just purchased a SWP 2144 CO2 regulator from lawson-his

http://www.lawson-his.co.uk/scripts/details.php?cat=Gas Weld/Cut Equipment&product=95190

however I am struggling to remove the out valve, I've tried wd40 to help but it just won't budge.

Does anyone have any tips ?

Remove the out valve?.... why on earth would you want to do that?

To swap it for a John Guest 3/8" x 1/4BSP Outlet Adapter.

Unless there is another way to attach the gas out ?

The blue cap??

Hopefully some pictures will help explain what I mean...

This is the regulator



Here is the valve that I think I want to remove (to the left)



And here is the JG adapter that I want to fit



Hopefully this makes sense ?

A little aside....try not to use oils or greases on gas valves, even non flammables .We are told that friction can ignite them .

Back on subject ,this NOT being a fuel gas it should have a normal R hand thread so could you not find a normal compression type fitting to mate the two ? Or a welding supplier will be able to sell you a hose barb fitting to fit onto the reg.....

Wrong adaptor!

You need (from memory) an adaptor with a 3/8" female thread. I picked up one from a local pnuematics shop that goes to 10mm air line, which works with normal beer gas line perfectly.

EDIT: I have the same regulator by the way.

Hmmm, looks like I didn't do enough research before buying then !

Thanks for the tips guys, now to find the correct adapter from somewhere.

Cheers.


Quick look on ebay, would this be what I'm looking for james ?

Looks like the right one to me. I'm 99% sure it's a 3/8" thread... and the lawson site advertises 3/8" accessories to go with the regulator.
