Hydrofarm HGGR50 (25 Pack), 1/2 Rubber Grommet, Black

After using not so cheap Home Depot grommets that leaked after a month of use, I changed over to Hydrofarm Grommets, so far so good. No signs of dry root, and no leaks.

When I bought this product I was under the impression that it would fit on the end of a 1/2 inch pvc pipe. No way will it fit I will have to try another product. Package said made in China

unreal how much disinformation is on this listing. these absolutely DO NOT FIT 1/2 pvc. im not sure what they do fit but its not 1/2 inch. huge waste of time!!!! for reference shed 40 1/2 inch doesnt even fit through a 3/4 inch hole without a grommet.

I purchased Hydrofarm HGGR50 Rubber Grommet for use with ½ inch PVC pipe. One of the comments said it could be used with a ½ inch PVC and 13/16 hole saw. There is no way they could be used as claimed. It put me in a hell of a bind. I had to improvise by using ½ inch CPNC pipe and a 7/8-inch hole saw. You need to remove the comments stating that it will work with ½ inch PVC. My satisfaction server will reflect my outrage.

3/4 hole and these fit perfect.

great quality grommets - actually look to be better quality than pictured. just what i needed for my dwc project! great value also - these would cost me $1 a piece at the local hydro store. would recommend for any hydro build!

Great product Easy to install with 13/16 inch bit and no leaks

Great working.

Fit perfectly

excellent and reliable. I use these for Dutch-bucket hydroponics, and also in construction for water buckets for chickens. I have not found any that leak.
