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

Well made and does the job on hydroponic Dutch buckets.

Does not fit 1/2 pipe

Great product

They work great for sealing houses in buckets for hydroponics.

So just to clarify the 1/2 is outside diameter so I think that makes the inside diameter 3/8. I will still put them to use just frustrating when I needed inside diameter to be 1/2

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.

3/4 hole and these fit perfect.

Quality

Its so easy using this product. Drill the proper size hole and insert it in and seat it right and presto, a leak proof seal for using barbed connectors.

I need 1 rubber grommet but 1/2 OK
