## Features

- ✅ Withstands 60 PSI : Built for high performance, the MRbrew carbonation cap holds up to 60 PSI without leaking. This cap features a large flat gasket and upgraded O-ring for a completely airtight seal—ensuring your beer stays fresh and carbonated overnight. Ideal for force carbonation and bottle conditioning.
- ⚙️ Universal Ball Lock Compatibility: Designed for versatility, the integrated keg post connects easily with both gas and liquid ball lock disconnects. The removable 5/16” beer barb supports both carbonation and liquid transfers—perfect for homebrew cleaning systems too. All parts are pre-assembled and secure, so there's no risk of accidental disassembly.
- 🧊Snug Fit for Standard 2L Soda Bottles: Featuring precise 1-1/8-8UN threading, this carbonation cap screws onto most 2-liter PET soda bottles securely and smoothly. Creates a leak-proof seal without excessive torque, making it an excellent tool for homebrewers who want to keep beverages carbonated longer and fresher.
- 🛡Premium 304 Stainless Steel & Food-Grade Seals: Crafted from high-quality 304 stainless steel, food-safe rubber, and silicone, this carbonation cap ensures long-lasting performance without rust, odors, or sharp edges. All sealing gaskets are perfectly fitted and stay in place during use, keeping your drinks clean and safe.
- 🍻Perfect for Homebrew: Re-carbonate soda, beer, or cold brew on the go—ideal for BBQs, tailgates, camping, or holiday parties. Also works great for running cleaner through beer lines using a small bottle setup, minimizing CO₂ waste compared to cleaning with a full keg. A must-have for every mobile homebrewer.
