Airlock - 3 Piece

3-Piece Airlock – Durable, Dishwasher-Safe Fermentation Lock

A reliable 3-piece airlock designed to protect your fermenter from oxygen and contaminants while allowing CO₂ to escape. Easy to use, easy to clean, and far more durable than traditional S-type airlocks.

Simply fill with sanitiser or pre-boiled water and insert it into your fermenter bung or grommet.

Why Brewers Prefer the 3-Piece Airlock

• Fully dishwasher-safe PP plastic — won’t crack like S-type airlocks
• Allows CO₂ to escape while blocking oxygen, dust, and microbes
• Easy to disassemble and clean
• Ideal for beer, mead, wine, and cider fermentation

Pro Tip

Fill your airlock with sanitiser or ethanol for the best protection.
If fermenting in a fridge, use salty water or ethanol to prevent freezing or evaporation.

A dependable, easy-clean airlock for every stage of fermentation.
