Simple Grommet – Airlock

What Is It?

For your S-Type Airlock, the simple grommet is a small rubber seal that fits into a hole in the fermenter lid. This will smooth out the drilled hole and provide a clean neat place for the airlock to go in, giving a good airtight seal as the airlock is inserted. The drill size we recommend is 12mm to provide a tight fit. The top and bottom are flared and wider than the hole, allowing the grommet to stay in place in the lid.

Why Do You Need It?

If you intend to drill a hole in your fermenter lid to insert an airlock, you need to make sure that the hole is completely round and sealed. The airlock must be tight against the hole for the seal to be effective. The grommet will fill any jagged edges or cuts in the lid and provide a perfect hole for the airlock.

How Do You Insert It In The Lid?

The grommet will need to fit over a 12mm hole that has been drilled into the fermenter lid. Hold the grommet at the sides and gently squeeze so that it makes an oval shape, and push over the hole making sure that the bottom flared part is underneath the lid and the top above. Gently push into the lid all the way around. You will need to push the grommet down at the edge for it to pop into place in the last part.
