These male quick connect (aka quick disconnect) fittings can easily be attached using one hand even with heavy brewing gloves.
The inside diameter of this Quick Connect fitting is 1/2″. This creates a full port design and will not restrict flow going through the barb. 1/2″ Female NPT (FPT) fitting can be threaded to any matching MPT fitting. Made by Spike Brewing.
