Ball Lock Keg vs. Pin Lock Keg: Understanding the Differences

When diving into the world of homebrewing, choosing the right keg is crucial for ensuring the best experience in storing and dispensing your brew. Two of the most common types of kegs used by homebrewers are ball lock kegs and pin lock kegs. While both serve the same fundamental purpose, they have distinct features that cater to different preferences and needs. Let’s explore the key differences between these two keg types and highlight some recommended ball lock kegs.

Key Differences Between Ball Lock and Pin Lock Kegs

1. Connection Mechanism

Ball Lock Kegs:

  • Quick Disconnect Fittings: These kegs use a ball-bearing quick disconnect fitting, which is simple to attach and detach. The quick disconnect locks onto the keg’s posts, one for the gas (CO2) and one for the liquid (beer).
  • Posts: Both gas and liquid posts are uniform in appearance, typically differentiated by a groove at the top or by a marking on the post.
Pin Lock Kegs:
  • Pin-Based Connectors: Pin lock kegs use a pin-and-notch system where the connectors latch onto the keg’s posts. The gas post usually has two pins, while the liquid post has three, making it easy to distinguish between the two.
  • Manual Connection: Unlike the quick-release nature of ball lock fittings, pin lock connectors need to be manually twisted onto the posts, which some users find less convenient.

    2. Size and Dimensions

    Ball Lock Kegs:
    • Taller and Narrower: Ball lock kegs are generally taller and more slender, making them a better fit in tighter spaces, such as a refrigerator or kegerator with limited horizontal room.
    • Common Sizes: The most common size is 5 gallons, though shorter versions are available for those with height restrictions.
    Pin Lock Kegs:
    • Shorter and Wider: Pin lock kegs are shorter but wider, which can take up more floor space but may be advantageous in setups where height is a limiting factor.
    • Standard Size: Like ball lock kegs, pin lock kegs are also typically available in 5-gallon sizes.

      3. Availability and Compatibility

      Ball Lock Kegs:
      • Widespread Availability: Ball lock kegs are more commonly found and are often the preferred choice in the homebrewing community. This popularity means that parts, connectors, and accessories are more readily available.
      • Versatility: The ball lock system is used by most modern homebrewers, making it easier to swap and share components among brewers.
      Pin Lock Kegs:
      • Limited Availability: Pin lock kegs were originally designed for Coca-Cola systems and are less commonly available today, leading to fewer options for parts and accessories.
      • Dedicated Use: Pin lock systems are more specialized, which may be less convenient for those who want a more universal setup.

        4. Ease of Use

        Ball Lock Kegs:
        • User-Friendly: Many homebrewers find ball lock kegs easier to use due to the quick disconnect fittings, which simplify the process of attaching and detaching gas and liquid lines.
        Pin Lock Kegs:
        • Secure Connections: The pin-and-notch system ensures a secure connection, but it requires more effort to attach and detach lines, which some users find cumbersome.

        5. Cost
        Ball Lock Kegs:
        • Typically More Expensive: Due to their popularity and the demand in the homebrewing community, ball lock kegs are usually slightly more expensive than pin lock kegs.
        Pin Lock Kegs:
        • More Affordable: Pin lock kegs are often cheaper, especially if you purchase used kegs that were originally part of soda dispensing systems.

          Choosing between a ball lock keg and a pin lock keg comes down to your specific needs and preferences.
