Description
Microppose Silicone Jar Lid Covers are reusable, food-grade silicone caps that go over your jar lids during pressure cooking — a foil replacement that shields filters and injection ports from direct steam and condensation. Sold in 6-packs for standard-mouth (70mm) or wide-mouth (90mm) jars.
Each cover is molded to shed condensation away from the filter as jars cool, so water doesn't pool on the filter disk. They're rated to 400°F, well above pressure-cooker temperatures, and wash up for the next run.

Why growers pick silicone covers
- Protects filters – Keeps direct steam and dripping condensation off filter disks and injection ports.
- Sheds condensation – The molded shape directs water away from the filter as jars cool.
- No more foil – Reusable covers replace a roll of foil for every sterilization run.
- Built for heat – Food-grade silicone rated to 400°F.
- Two sizes – Standard-mouth 70mm and wide-mouth 90mm jars.
What's included
- Six Microppose silicone jar lid covers in your choice of standard-mouth (70mm) or wide-mouth (90mm)
How to use them
- Prep your jars. Fill and close your jars with their filter or injection-port lids as usual.
- Cap them. Press a silicone cover over each lid.
- Sterilize. Pressure-cook or autoclave the jars with the covers in place.
- Cool covered. Leave the covers on while jars cool so condensation runs off instead of onto the filter.
- Remove and reuse. Take the covers off before inoculating, then wash and dry them for the next batch.
Pick your size: The 70mm covers fit standard (regular) mouth jars, and the 90mm covers fit wide-mouth jars.
