They are designed wide enough that they seat firmly against the roof of any brand Mason jar plastic cap completely underneath the threads and cannot fall out while screwing the lid onto or off the jar. They are GUARANTEED to provide an airtight and leak-proof seal. We tried the narrower red rubber seals with the smaller outer diameter. They tend to become displaced while tightening the lid, and unfortunately, they did not keep our fermentation jars airtight (see photo). QRP SEALS provide a perfect airtight, anaerobic enclosure while fermenting Kimchi (vegetables) or Kombucha (tea). We ferment on a very large scale, and QRP SEALS do resolve the airtight issue. When testing QRP SEALS by placing water in a jar and shaking the jar, we experience no leaks. We understand your health concerns. QRP products were developed to help our director overcome prostate cancer. ALL QRP products are made from USDA Food Grade BPA-free Compliant Silicone and are produced by a reputable food container manufacturer for food products only. CAUTION: OVERTIGHTENING COULD DAMAGE THE SEAL AND MAKE IT DIFFICULT TO REMOVE THE CAP! QRP SEALS HAVE NO TAB AND ARE NOT A GOOD FIT FOR GLASS STORAGE CONTAINER LIDS. 2016 Quality Reliable Products, All Rights Reserved. ## Features - SUPER FAST SHIPPER ~ SHIPPED SAME DAY EVEN FOR MOST ORDERS RECEIVED BY 5 PM CST ON SATURDAY!

I like supporting this company. The owner sent his story about how fermented foods has benefited his health. And how he donates some of his profits. I have recommended these seals to 8 friends. They like this owner too. We like supporting good people. Besides these are the best seals out there in my opinion. ### ⭐⭐⭐⭐⭐ Great fit and seal *by T***D on March 27, 2018* These fit inside the regular mouth plastic lids great and no leaking! I make my own Elderberry syrup and these fit great on my mason jars. And I love that this company is Christian and some of the money goes towards Christian organizations. ### ⭐⭐⭐⭐ Four Stars *by M***N on March 13, 2017* They work --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/41342999-qrp-mason-jar-seals-reusable-food-grade-silicone-stay-inside](https://www.desertcart.tn/products/41342999-qrp-mason-jar-seals-reusable-food-grade-silicone-stay-inside) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-13*
