Adaptor for inert regulator to manifold gauge hose?

admin

A weird question for you guys.  I want to try making this bottle/lightbulb project and I need to pump an inert gas into the bottle.  I've got the inert tank and regulator in my welding equipment so I blithely bought a manifold gauge thinking I could hook them right up.  I can't.  The manifold hoses are a bit too small.  Does anybody know of an adaptor that will allow me to hook up the manifold hoses to my regulator?What I have:Regulator: Victor 450Manifold gauge set: from Ebay.  A guy at the local HVAC shop said the manifold connector is "just quarter-inch", so I don't know if it has any special specification.Also, I've never worked with a manifold guage set so if you see any safety issues hooking up my 120cf inert bottle to the set let me know.Thanks!
