Western Quick Disconnects w/Check Valves - Regulator To Hose

These are awesome

Great for versatility. I can swap between my mini torch, fuel saver, and big rosebud without needing wrenches and leak check. Make sure you are paying attention to buying regulator end vs torch end. There is another model with an integrated flashback. I hope their longevity matches their usefulness. So far so good after 2 years
