'Craftsman' is a brand name given to torch equipment manufactured under contract for sale in the huge US retail chain Sears & Roebuck.. I think these regulators were manufactured in the USA by Harris for Sears and sold under the Craftsman name...

The oxygen bottle side thread is CGA-540 and the hose output side is a CGA-022.. please note that the CGA-022 threaded output connector, otherwise known in the US as 9/16" or 'B-Size' is NOT THE SAME as the 5/8" thread commonly found on NZ and aussie torch gear by companies like CIG or stuff manufactured for BOC / NZIG.. Comet torches, regulators and the like all use 5/8" hose connectors.. It's actually a standard itself from an old imperial 'british pipe thread' gauging system that survives somehow...

Perhaps because they are made in much larger numbers, the brass fittings and torch accessories in these US sizes are very cheap online.. a quick amazon search turned up all one could ever need in terms of hose barbs / thread adapters etc... most with free shipping to NZ...

Check my other listings too.. I have a couple of sets of US 9/16" hose barbs, flashback arrestors and torches listed separately...

The condition is pretty good.. please do fire away with any questions you have regarding any compatibility issues etc.... Id rather sort it out here.. After a bad experience a while back, I won't accept anything back because it's the 'wrong size' for your application...
