What is a Ball Lock Keg?

A ball lock keg is a stainless steel, pressurized container originally used for soda, now widely adopted in the homebrewing community for storing and dispensing beer. Named after its “ball lock” connectors for gas (in) and liquid (out), this keg type has become the standard for many homebrewers and commercial setups.

Why Choose Ball Lock Kegs?

✅ Easy to clean and maintain

Ball Lock Keg Setup: Step-by-Step

Setting up your ball lock keg system may seem intimidating at first, but it’s surprisingly simple with the right gear.

What You’ll Need:

  • A clean, sanitized TMCRAFT Ball Lock Keg

  • CO₂ tank with a dual-gauge regulator

  • Ball lock connectors (gas and liquid)

  • Beverage lines and taps

  • Keg lube (optional, for O-rings)

Step 1: Clean and Sanitize

Before anything touches your beer, clean and sanitize your keg and all lines thoroughly to avoid off-flavors or contamination.

Step 2: Connect the CO₂ System

Attach the gas line to the gas-in post (usually marked or has a notched collar) and connect the CO₂ regulator to the tank. Slowly increase pressure to purge oxygen from the keg.

Step 3: Fill Your Keg

Transfer your beer into the keg via siphon or gravity. Fill to about 90% capacity to allow room for pressurization.

Step 4: Seal and Pressurize

Lock down the keg lid and apply CO₂ pressure—usually around 10–12 PSI for typical ales. You can force carbonate or let it sit at serving pressure for a few days.

Step 5: Pour and Enjoy

Once carbonated, attach your tap to the liquid-out post, chill the keg, and enjoy fresh beer straight from the tap!

Maintaining your ball lock keg system keeps your beer tasting great and your gear running smoothly.
