    I wasn't sure if this was the exact product I needed, because I found it from a basic Google search. However, it was cheap, came quickly, and works perfectly! Thanks Kegworks!

    Good enough for carbonating homebrew in a growler
    We homebrewed a dry porter and carbonated it in the growler. The cap effectively kept the pressure inside, and the beer carbonated properly (it may even be a tad over-carbonated).

    The cap feels well done, lightweight, and is easy to clean. For this low price, I definitely recommend it as an alternative to the regular plastic cap.

    I was looking all over for growler caps and either vendors did not sell them or they sold them at too high a price. These are exactly what I am looking for and the price is right.

    Have several growlers with caps that are moldy
    KEVIN D on Apr 1, 2019
    I picked these because if the seals on the caps are truly as pictured, I know they will hold pressure. This is the only style cap that will hold pressure.

    Poly seal/rubber gasket inside cap helps to keep cap tighter without leaks.

    I brew my own kombucha, and I reuse kombucha bottles. Unfortunately the plastic caps on the bottles are not airtight, so i'm replacing the caps with these, to help with the fermentation process/ keeping air out.

    Looks like they have the rubber-type seal which is FAR better than the paper-type seal.

    I have a 32oz growler with a missing screw cap. What size replacement cap do I need?
    A shopper on Nov 8, 2016
    BEST ANSWER: Hello, I believe you're looking for the cap to our Boston Round Growlette or similar style growler. Unfortunately, we don't carry them at the moment. We are currently looking for a source for this item. Please check back with us another time. Cheers!

    Boston Round Growlette Amber Beer Growler - 32 oz
    Do these caps fit a 32 oz. growler?
    A shopper on Jan 2, 2016
    BEST ANSWER: Thank you for your question. This size growler cap won't fit the 32 oz growler we sell. If you have another in mind, the cap diameter is 1 1/2”. You can measure to see if it will fit.

    Are these bpa free? New law in California for BPA requires signs at my brewery unless the caps are documented as bpa free.
    Jason K on Feb 17, 2018
    BEST ANSWER: These caps are not BPA free. We just received notice from the vendor and have updated the product page information accordingly.
    Are these caps 1 inch x 1/2 inch?
    A shopper on Sep 22, 2017
    BEST ANSWER: These caps are 1 1/2 inch in diameter.
    Hello, I have a 1/2 gallon growler what size cap do I need?
    Arlene M on Jan 22, 2017
    BEST ANSWER: Hi Arlene, most growler openings are a standard size and thread, but there are some variations. This cap measures 1.5" in diameter. I would measure the opening of your growler to see if that will work!
