ere's a lot of four 38/400 size drilled caps to fit an airlock onto a standard one gallon jug or cubitainer. The hole is approx 3/8" and when an airlock is inserted an airtight seal is created without the need for a grommet.  These are the same caps we sell with our Airlock/Jug combos.  Check our other items!
These are made from natural color food grade plastic.  They fit a 38mm jug mouth which is about an inch and a half outside to outside, and about an inch inside to inside.  This means that they fit standard 1 gallon and 1/2 gallon jugs.  They work with all standard 3/8" airlocks including the 3 piece, S type, Mini, and Double Bubble.
For the longest time we made our own caps by drilling a 1/2" hole in a plastic cap and putting in a grommet.  It was time consuming and the drilling was a little dangerous. Now we just reach into the bag for one of these and it's done!
