I lift the lid as I tighten and make sure to wet the gasket with water before I install, I did not leave the lid loose or use any aluminum foil on the top prior to pressure cooking and it worked fine and lids stayed tight. The trick I think is lifting the lid upwards as you tighten it on wide mouth ball brand jars. I like that the PTFE filter has enough flow where I can PC them and not need to tighten or mess with lids in front of a flow hood. I'll test them with grains next and see how it goes, but I'm expecting no issues. I do plan to replace one of the injection ports with a filter patch for grains though because I use half gallon grain jars, if I was running quart jars I wouldn't have any concerns using the included filter. Suggestion for seller: Instead of having 2 injection ports, it would be better to have 2 PTFE filters for better gas exchange. ## Frequently Bought Together - Ks-Tek 3Pcs Wide Mouth Liquid Culture Lid Food Grade Plastic Grain Spawn Cultivation Mason Jar Lid with 0.22um PTFE Syringe Filter & 20mm Self Healing Injection Ports For Mushroom - Weewooday 8 Pieces PTFE Magnetic Mixer Stirrer Bar, White Color Stainless Steel Laboratory PTFE Stir Plate Bar, Mixing Plate Magnet Stick (30 mm/ 1.18 Inch) - HiMedia RM001-100G Peptone, Bacteriological, 100 g --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/327363225-ks-tek-3pcs-wide-mouth-liquid-culture-lid-food-grade](https://www.desertcart.jp/products/327363225-ks-tek-3pcs-wide-mouth-liquid-culture-lid-food-grade) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-27*
