KilnerFermentation Lid with Air Lock, Silicone

Functionality wise this is great as you can convert a kilner jar you already have for another use.Sturdiness wise it's flexible which is great for fermentation.Look s wise it's simple but effective.Very good value for money.

After spending ages reading ambiguous info on airlock system and whether or not they fit with particular jars I opted for this one. It is a good quality silicone which provides a snug fit for a 10cm “wide mouth’ Kilner jar.I had purchased some new 1 litre “Wide mouth” Kilner jars, as pictured, fits a treat.(Tried with regular 9cm wide Kilner jars which it does NOT fit)

As a cheaper option you can buy their standard 3L jar (£8.80 in sale) and add this lids for the perfect small homebrew. A lot of reviews said the lid comes off the set they sale but luckily if you buy the standard jar and remove the glass lid you get the metal clasp to hold the silicone lid in place and it works perfectly. It's a great cheaper option that works a lot better.

Fits perfect and does not shrink.

I have not used the product as yet so hard to say much but product is as expected so far.
