Get back to serving real ale today with this CO2 Keystone Body with Blanking Plug for older-style, cask ale extractors.


    If you have a older-style vertical extractor, you may find that one of the first pieces to wear out is the keystone body. Never fear! This replacement cask part will keep your cask ale flowing.

    This cask part is made from clear, high-impact resistant, food grade plastic for safety and longevity, while its duck bill valve only lets CO2 into the barrel when the beer is being dispensed. This non-return valve maintains the freshness of your cask conditioned beer.

    Maximize the longevity of your real ale with this barrel spigot. It will keep your cask conditioned ale tasting great for a longer period of time.

    • Replacement for older style rigid vertical extractors
    • Has a blanking plug
