Black Growler Caps Large

Keep your craft beer fresh and carbonated with this professional-grade Black Phenolic Growler Cap. Designed with a 38-400 thread size, this cap is the industry-standard closure for glass growler bottles used by breweries, taprooms, and homebrew enthusiasts alike. The cap features a durable phenolic (thermoset plastic) construction that provides a rigid, reliable seal every time. Its integrated polyseal cone liner creates an airtight barrier against the bottle opening, locking in carbonation and preventing oxidation to preserve the flavor and quality of your beverage. The classic black finish gives a clean, professional appearance that complements any growler bottle. Phenolic caps are preferred over standard metal caps for their superior chemical resistance and consistent sealing performance. The polyseal liner conforms to the lip of the bottle upon tightening, ensuring a leak-proof closure whether the growler is stored upright or on its side.
