Ces couvercles en silicone pour pots Mason à « large ouverture » sont conçus pour protéger vos filtres adhésifs et vos orifices d'injection de la vapeur. Lorsqu'ils sont appliqués sur le couvercle de votre pot, ils empêchent les filtres de se décoller et prolongent leur durée de vie.

Les couvercles sont autoclavables, réutilisables et plus écologiques que l'utilisation de papier d'aluminium. Chaque couvercle est fabriqué en silicone de qualité alimentaire et peut supporter des températures allant jusqu'à 204 °C (400 °F).

*Couvercles de pots et filtres non inclus.

Awesome and easy!

Love these silicone jar covers and wish I had gotten them sooner. Easy to use, no waste, and less time in prepping your grain jars. Mosy definitely recommended.

Worth it!

I bought these along with the wide mouth jar lids and they worked as said, they replaced the aluminum foil i was laying over my lids in the pressure cooker and after wards they help me easily lift the jars out the heat without getting burned by the hot grain and glass, just thought that was neat.

No more aluminum foil!

I can’t tell you how much frustration this product has saved me. I used aluminum foil for years to make my own spawn jars. They always let extra moisture in, would tear, cost me extra money to buy more foil. I’m done with it all. The only product I’ll use to cover my jars to make spawn are these. Very easy to use, easy to clean, very little moisture let in…. Just very high quality. Highly recommended!

Mitch, thanks so much for this raving review! So happy we were able to make your life a little easier. Don't hesitate to reach out if you ever need anything, we are here to help!

Finally a cost effective alternative to aluminum foil.

Just did my first run with these and couldn't be happier!
No more than a few drops of water underneath then foil wrap.
They are best suited for a modded lid because you don't want to leave them on as a cover during spawn jars colonization. My old lids just had a punched hole for innoculation and I left the foil on as a dust cover.
No complaints here!

Thanks for the great review, Kevin. We're so glad everything is working out for you! The team is here if you ever need anything.
