Simply Sauer Vegetable Fermentation Kit for Wide Mouth Mason Jars - Oxygen Pump and Airlocks - 5 Piece Kit

Using these in combination with Ball Jars has been the best solution for home fermenting I have found. Super simple and clean and effective.

These fermentation lids are literally awesome!!! Screw onto wide mouth lids with ease and are made of quality plastic, they are extremely durable and well made. Was unsurr about the pump but after watching my saurkraut, i see how incredibly useful the pump is to remove the excess gas by removing it. I can forsee they shall last a long time thru many many batches of fermentations. I Def recommend these to anyone looking for a quality product that surpassed my expectations. Thank you for an excellent product. Will most def purchase more. Haven't found any that I can just purchase without the pump....Def don't need an excess of pumps with every 4 lids bought. Just a thought!!!

I've had a set for a few years and used them in making Kefir. They work very well and the tops are still perfect. Now this new set will be to ferment vegetables. So, having purchased these for the 2nd time speaks for itself. They are simple, durable, effective and a great value.

Fonctionne à merveille. Bonne qualité de plastique, même après plusieurs années d'utilisation, il n'y a pas de signe de jaunissement ou d'affaiblissement du plastique. La puissance de vacuum applicable est très honorable. Et si la pression devient positive dans le pots, le couvercle permet son évacuation sans laissé entré d'air.

Come prodotto è davvero ottimo e mantiene la pressione, se maneggiati con cura durano a lungo.
