Duotight 8mm Liquid Out Ball Lock Disconnect

Duotight 8mm Liquid Out Ball Lock Disconnect

This is the liquid-side ball lock disconnect that connects your keg to your beer line without barbs, clamps, or hose clamps. The Duotight fitting is built right into the disconnect, so your 8mm EVABarrier tubing pushes straight in and holds. No tools, no fuss.

It's a lot more compact than the old plastic ball lock QDs most homebrewers started with. That smaller footprint matters when you're stacking kegs in a kegerator or keezer and every inch counts.

Handles Sanitizers and Cleaners

The body is made from chemical-resistant material, and the springs and ball bearings are stainless steel. That means it stands up to phosphoric acid, caustics, and the usual cleaning chemicals you'll run through your lines. And when you need to deep clean it, the cap unscrews by hand so you can pull it apart completely and sanitize every surface.

Matching Your Tubing

The 8mm OD version is the most versatile size in the Duotight lineup. It works with either 4mm or 5mm ID EVABarrier tubing:

• 4mm ID tubing – use for standard 5-6 ft. beverage lines.
• 5mm ID tubing – use for gas lines or longer 10-12 ft. beer runs.

This is the liquid-out (beverage) disconnect, so it connects to the liquid post on your ball lock keg. If you need the gas side, look for the matching gas-in version.
