Cask Ale Wing Nuts / Burrs – Open & Closed, 3/4" BSP, L & Y Thread

Cask Ale Wing Nuts and Burrs – Open and Closed Options

These Cask Ale Wing Nuts, also known as cask burrs, secure compatible connections on cask taps and flexible ale extractors. Manufactured from hard-wearing acetal, they provide a durable replacement for worn or damaged nuts in your cask dispense system.

Available in open and closed versions, with a choice of 3/4" BSP, L (London) or Y (Yorkshire) threads.

Choose the Correct Thread

Select the thread that matches your existing cask ale equipment:

• 3/4" BSP: British Standard Pipe thread
• L thread: London thread
• Y thread: Yorkshire thread

These thread types are not interchangeable. Check both the thread and whether you need an open or closed version before ordering.

Compatible Cask Ale Equipment

With the correct fitting selected, these wing nuts are suitable for use with our:

• Single Flexible Ale Extractors
• Double Flexible Ale Extractors
• Compatible cask taps

The winged design provides a convenient grip when fitting or removing the nut. A suitable washer or sealing component is required to form a sealed connection; the nut alone does not provide the seal.
