Stainless Steel Square Jockey Box Coil 90ft(28meter) 2-way 5/16(8mm)OD Tubing High Efficiency Draft Beer Box DIY Kegerator Stainless Steel Square Jockey Box Coil 90ft(28meter) 2-way Jockey box coils are designed to cool your beer as it travels through the coil. They sit inside a cooler, in an ice bath. With regular cleaning, these 304 stainless steel coils will not cause funky flavors in your brew over time. This jockey box coil is designed in an innovative square shape to help provide a snugger, more secure fit in your cooler. It utilizes unique spacer legs to create a slight elevation that allows your ice bath to chill from underneath, resulting in a more consistently cold, less foamy product. In 5/16" outside diameter, these coils are the right size for the majority of larger jockey box kits. Set up your jockey box no more than 10 feet from your ice cold keg. Attach the beer line from the top of the keg coupler to the cooler coupling, and the air line from the outlet barb on the CO2 regulator to other side of the coupler. Adjust the keg regulator to 40-60 PSI based on your setup. Keep both the jockey box coils and keg cold throughout to avoid foaming (no more than 40 F). Be sure to wash out your lines and coils after each use. Please note: this product listing includes the square coil only.
