QDB33 Argon Inert Gas Regulator to Hose Quick Connect/Connector Disconnect Set, Western Enterprise

Works well on the back of my tig welder since its a dual purpose machine

I’ve tried to like this but it leaks inside the connection! Multiple times we’ve tried these and idk about everyone else but when we see bubbles,( even if it seems slow ) then that’s leaking$$. Gunna call the manufacturer personally and ask them about this issue. Have three of these and everyone of em leaks .

I purchased two of these Western Enterprises QDB33 quick disconnect units and received them 9/2/21. Yup, they have a very nice, smooth connect and disconnect function, but I really require the reverse-flow check valve function that both Western Enterprises site and this product posting both indicate that this unit possesses. That is the main reason I purchase these. I have an Argon tank and a C25 tank connected to a valved-Y to supply my GMAW (mig) machine. Sometimes I want less CO2 in my gas, so I turn my Argon tank on with the appropriate flow rate to mix to approximately 95% Ar and 5% CO2. In the past, I suspected that my tank regulators were allowing the the lower-pressure tank to allow ingress of some of the gas of the higher-pressure tank when both Y-valves were opened due to the regulators not being adequate check valves themselves. This is the main reason of needing these check valve / quick dis-connectors. A big disappointment due to no check-valve in these units.

I was like Maaaaaaaaaaan 30 bucks for real, but its worth the cost really solid made fitting

Great QD. I know they dont leak because I left a bottle on. These are great for supplying a multi process welder with the required gas if your welder, like mine, has a single gas input connection and it can do MIG and TIG. Two bottles; 2 QDs problem solved!

This connector does not have a check valve as described. I wasn’t able to use it. The connectors were incompatible with my regulator. Thankfully I was able to send it back

Quality construction, used to quickly attach/remove tig torch.

Very fast shipping and just what I ordered

They are quick come ext and makes my job easier

I do mobile welding and I use it to hook my regulator to my tig torch and all you need is an adapter
