    Connecting gas to a Miller Cricket??

    I acquired a Miller Cricket XL and it already has the gas hardware kit installed on it. I need a nipple fitting that goes into the solenoid valve to connect the gas supply hose. The Miller manual describes the solenoid valve as "1/4 IPS port 1/8 orf".

    Can someone here decipher that for me? I looked up IPS and it describes it as Iron Pipe Standard. Does the 1/8 orf mean orifice size?

    Thanks for your help.

    5/8-18 inert gas to a 1/4" IPS is a specialized part likely originally supplied with the solenoid kit. You may have to try a 1/4" NPT and epoxy the threads so it seals.

    I found what I needed. It's a 1/4" Inert Kit, Radnor part number 64003964

    That is a standard 5/8-18 inert gas fitting to barbed hose. Nothing there to fit 1/4" IPS that you said you were trying to fit. Made it sound as though the 5/8-18 fitting was not in the solenoid valve.

    Knew you didn't find and 5/8-18 to 1/4" !PS as I looked for 2 hours for you. Oh boy. You only needed a standard 5/8"-18 fitting/hose. Lol.

    5/8-18 is a standard inlet size for Miller machines and Lincoln too. Those are dime a dozen and standard for inert gas. You don't have to look for those. They are everywhere by the dozens.

    Just get the proper hose already made up if it really is 5/8-18 inert gas thread you have and are trying to fit.

    Premade hoses are cheap. Unless your regulator is not 5/8"-18 and yor using a barbed fitting connection there to.

    Even if Regulator only has nipple. You can take that out and usually get 1/4" NPT to 5/8" -18 B size fitting and then use premade hoses. So much cleaner installation with the premade hoses.

    I appreciate the time you took looking. The reason I was looking for 1/4" IPS is because that's what the Miller factory manual for that machine had listed. After further inspection I realized what was actually needed.

    Yes sir. I understand that is exactly what happened. The solenoid description had us on a goose chase. Happy for you it was so simple after all.

    Don't no why but as I've gotten older I make things complicated from time to time. It should be the other way around

    That is too funny. I know I never used to forget where I parked the dang car when I come out of Lowes. Now iIf it weren't for the panic button I would be reporting it stolen half the time.

    What was the straight axle '65 ? Love the old straight axle's under a early front end.

    At the time I joined this sight I was starting to build a 65 Plymouth altered wheelbase drag car with a straight axle so I thought that would be a good username. I ended up selling the 65 to finance finishing another car but would still like to do an altered wheelbase car one day.
