PET Bottle Caps – 28mm

These PET Bottle Caps are designed to fit standard pop bottle-style plastic bottles, including most 500 mL and 2 L PET bottles used in homebrewing. They fit the common 28 mm PCO 1810 thread, the same size found on typical soft drink bottles, making them an affordable and convenient solution for bottling carbonated beverages like beer, cider, or soda.

Great for both reusing commercial bottles and capping PET bottles purchased specifically for brewing, these caps create a tight, pressure-safe seal that holds carbonation and keeps your brew fresh. Ideal for bottlers who want a lightweight, portable, and unbreakable option—especially for camping, hiking, or other outdoor adventures.

• Fits standard 28 mm PCO 1810 threads
