Frequently bought together

Airlock-to-Lid Adapter — 1/2" NPT × 3/4" Slip (Cork) 🫧

Thread-in fitting that lets a standard airlock + cork seat securely in your lid.

This adapter threads into the lid and provides a smooth 3/4" slip opening so a drilled airlock cork can press-fit and seal cleanly.

How it works ✅

  • Male end: 1/2" NPT threads (screws into the lid)

  • Top opening: 3/4" smooth slip (accepts the airlock cork)

Fits

Threads into the lids of most later-model MiniBrew fermenters: F8B, F15B, F25, F40, F98, F101 (not the 6.5G model).

Note

Many newer conicals already include an airlock port/hole and airlock hardware—check your fermenter kit first to avoid duplicate parts and save on shipping.
