What size are the threads on a beer tap?

Answered by Andrew Fritz

The threads on a tap come in two different sizes: 3/8″-16 and 5/16″-18. The larger size, 3/8″-16, is commonly used for displaying tap handles. This size is specifically designed to fit the thread of a standard American beer faucet. So, if you are looking to attach a tap handle to a beer faucet, you would typically use a ferrule that matches the 3/8″-16 thread size.

On the other hand, the smaller size, 5/16″-18, also has its uses in the world of tap handles. Some tap handles are designed to attach to the smaller 5/16″ thread size. This allows for versatility in creating and customizing tap handles to fit different faucets or personal preferences.

It's worth noting that these thread sizes are not exclusive to beer taps. They are commonly used in various industries and applications where threaded connections are required. However, in the context of tap handles, these thread sizes are particularly relevant.

As a sommelier and brewer, I have had the opportunity to work with different types of tap handles and faucets. I have come across both the 3/8″-16 and 5/16″-18 thread sizes in my experience. It's fascinating to see the variety of tap handles available, each with its unique design and attachment mechanism.

When creating tap handles, it's essential to consider the thread size of the faucet you intend to use. Ensuring a proper fit between the tap handle and faucet is crucial for stability and functionality. It's also important to choose the right ferrule that matches the thread size of your selected tap handle.

The threads on a beer tap come in two sizes: 3/8″-16 and 5/16″-18. The larger 3/8″-16 size is commonly used for displaying tap handles, while the smaller 5/16″-18 size offers versatility in tap handle customization. Choosing the appropriate thread size and ferrule is essential for a secure and functional attachment between the tap handle and faucet.
