Gardner Bender GHG1538 Black Rubber Grommet for Enhanced SEO Review

Perfect replacement for the airlock hole on my 6 gallon plastic pail. The bushing that came with the bucket somehow broke so wasn't airtight. I replaced it with one of these which fits perfectly.

USING THIS APPLIED TO A HOLE IN A PLASTIC LID WITH A LOCK PRESSED FOR FERMENTATION, MAKING A VERY CHEAP AND PRACTICAL SYSTEM FOR LACTO FERMENTATION. MY FIRST BATCH of sauerkraut is COOKED. THE BUSHINGS THEMSELVES ARE WELL MADE AND SEEM VERY STRONG. YOU ARE WORTH WHAT YOU TELL YOU.

part no. ghg-1538 High quality rubber bushings. The 3/8" OD hose fits these sockets very snugly. Use a 1/2" hole size if it's not waterproof. I can use a 64 step drill to make it more waterproof. I will putting them on the bottom of DWC buckets that hold 3 gallons. Let me know whether they like it or not. I'm just tired of lugging full buckets of nutrient solution out of the greenhouse to throw away, and the tomato roots along with it free, so I hope I can fix this problem.
