Thanks.** A: NO! Don't ever try to force carbonation into a glass bottle, unless you want to be blasted with shrapnel from the bottle when it explodes! These are for plastic PET bottles only. **Q: What size is the big flat o ring on the inside? I need a replacement for my carbonator cap.** A: Hello,the size of the big O-ring inside are 26mm(outside diameter),18mm(inner diameter),4mm(line diameter).Thank you ! **Q: I've just got one of these, and it leaks when connected to a normal pet bottle. is this what the o-ring is for? or do i have a deffective unit?** A: Make sure the inner metal piece..the one with the hose Barb..is tight. It screws into the main part of the cap. Also that large washer is key to getting a good seal on the bottle. Mine gets screwed down so tight that when I remove the cap it's inside the mouth of the pet bottle. **Q: will this take both liquid and gas assemblies?** A: Yes, you can use the liquid or gas assemblies ( liquid ball lock or gas ball lock) ## Frequently Bought Together - FERRODAY Stainless Steel Carbonation Cap Forced Carbonation PET Bottle Filling 5/16 Barb CO2 Coupling to Carbonate Soda Beer Stainless Steel PET Bottle Carbonation Cap + O-ring + Gasket - FERRODAY Ball Lock Gas Line Assembly 5ft Red Long Tubing 5/16 Ball Lock Gas Disconnect Set Home Brewing Kit Ball Lock CO2 Gas Hose Assemble for Draft Beer Home Brewing - Kegco KC LH-542 Draft Beer Regulator, Chrome --- ## 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.sn/products/323783811-ferroday-stainless-steel-carbonation-cap-carbonator-cap-with-5-16](https://www.desertcart.sn/products/323783811-ferroday-stainless-steel-carbonation-cap-carbonator-cap-with-5-16) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-18*
