Ø26/28 mm demijohn stopper with a closure

We would like to present an innovative and extremely practical Ø26/28 mm stopper, intended for sealing carboys and demijohns. The stopper has a permanently attached, closeable opening for the airlock, as well as a special flange that prevents it from being pushed to the inside of the carboy or demijohn.

• Innovative addition - the stopper has a permanently attached, closeable opening for the airlock
• The robust material - a thermoplastic elastomer - of which the stopper is made provides it with adequate strength and flexibility.
• Closure with "click" function - allows the stopper to be closed after the fermentation process has been completed - the "click" sound provides certainty that the stopper has been closed tightly.
• Special flange - makes it easy to remove the stopper and at the same time prevents it from being pushed to the inside of the carboy or demijohn.
• Made in Poland - a highest quality Polish product.

All airlocks in our product range fit the stopper.
