Plastic PET bottle and Growler caps

  • $2.49

Plastic screw-on caps for both PET bottles (28mm and 38mm) as well as Growler/Jug caps (38mm). These are low cost, easy to clean and sanitize, and will last for many uses. 

  • 28mm fits 500ml (16oz) and 1000ml (32oz) plastic PET beer bottles
  • 38mm fits 1000ml (32oz) and 2000ml (64oz) glass growlers, as well as 4000ml Glass jugs.

We have three types of caps (also known as closures) available;

  1. The white plastic caps are foam lined and perfect for everyday use and storage. Clean and sanitize after each use. 

  2. The white Tamper Evident caps (28mm) have a plastic liner and a ring that separates from the closure when it is opened. You can still reuse the cap after cleaning, but the tamper evident portion is single use. 

  3. The black PolySeal caps are a step up from that. These caps form an exceptionally tight seal and offer a good chemical barrier. This liner molds itself around the sealing areas of the finish as the cap is screwed on, virtually eliminating leakage, evaporation, contamination, binding and backing off. Available in 38mm size only.
