These silicone 'wide mouth' mason jar lid covers are designed to protect your adherable filters and injection ports from steam. When applied over top of your jar lid, they prevent filters from peeling and prolong their life.
Lid covers are autoclavable, reusable, and more eco-friendly than using aluminum foil. Each cover is made from food-grade silicone and can tolerate temperatures up to 400 F (204 C).
*Jar lids and filters not included.

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.
