The Western Inert Gas Quick-Connects allow you to quickly connect/disconnect from your regulator or backpurge device. Sold as the QDB33 for the quick connection from the regulator or QDB34 as a quick connect from hose to hose. I personally have my entire welding shop outfitted with these quality, made in USA quick connects.

New for 2020/2021 we have added the OSHA compliant KwikLok Quick Conneect fittings. These cannot be disconnected unless you line up the Sleeve Lock Feature. Will not disconnect by means of a straight pull.
