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

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.

Easy install in 5 gal buckets

This gromet is rather small to be using with PVC however, use 3/8 pipe and you should be good to go!

A +

Working perfectly in my bucket gardening.

I need 1 rubber grommet but 1/2 OK

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.

Quality

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

These are the cheapest way to add a sight glass to your bucket
