Out of all the ways to attach silicone tubing to your brew kettle we like quick connect ball lock fittings the most. The ease of connecting/disconnecting and cleaning is unmatched by standard hose barbs, cam locks or tri-clamps. These fittings can easily be attached using one hand even with heavy brewing gloves.
The over sized barb (5/8″ OD) is specially designed for our 1/2″ silicone tubing. The larger size does two things:
1) It stretches the tubing over the barb creating a tight fit requiring no hose clamps.
2) The inside diameter of our barb is 1/2″ compared to standard 1/2″ barbs which have a smaller 3/8″ size. This creates a full port design and will not restrict flow going through the barb.
