Joenos grey bung: 17 mm hole for Hobby II or without hole

The grey bungs have the standard size 38 × 45 × 33 mm and fit openings of about 35 to 42 mm inner diameter – all Speidel barrels in our range and demijohns from 10 litres.

The bung with 17 mm hole takes the Arauner Hobby II airlock. The bung without hole seals the demijohn or barrel airtight after fermentation. Both are made of food-safe rubber, reusable and easy to clean.
