Stainless Steel Carbonation Cap for PET Bottles

Carbonate Drinks in Standard PET Bottles with Ease

This stainless steel carbonation cap allows you to quickly carbonate and re-carbonate beverages directly in standard plastic (PET) bottles. Designed for homebrewers and beverage enthusiasts, it connects to a CO₂ line to turn everyday soda bottles into portable, pressurizable containers for beer, soda, sparkling water, and more.

Constructed from corrosion-resistant stainless steel, the cap is built for frequent use and long service life. The precise threading and integrated gas post ensure a secure, airtight seal on most common PET soft drink bottles, helping maintain carbonation during storage and transport. Its reusable design makes it a practical accessory for any home draft or kegging setup.

• Durable stainless steel build - Resistant to rust and wear, suitable for repeated pressurization and long-term use.
• Ideal for take-along bottles - Fill from your keg, cap, and take a freshly carbonated drink on the go while preserving fizz.
