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

They are quick come ext and makes my job easier

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

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!

Have not used it yet.

Great addition to the mobile tig rig

Reliable Product.

Way overpriced. But they work.

Love them , this is a nice addition to my welding set up easy to install Soopers temple to switch gases. The only downside and it’s just for my situation they are kind of long and I don’t have a whole Lotta room to work with
