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

Great quality. Better than the home depot grommets.

Quality

Inner diameter is 1/2. Previous reviewer got this wrong.

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.

No leaks, strong durable material. Will buy again.

Item was exactly what I wanted unfortunately I bought them too small. But the material is thick and sturdy. Will be buying bigger size with same manufacturer.

I bought these with Hydrofarm AAEL50 Active Aqua (10 Pack), 1/2 Elbow Connector, 1/2-Inch, Black, based on reviews and comments for other buyers. The grommet and the elbow complemented each other for a perfect fit. I used them to make self-watering 5-gallon bucket planters. The grommet seated perfectly in 3/4 drilled-out hole. The elbow just slipped right in. The rubber material was smooth and elastic, not rough and cracked as happened to old rubber.

Easy to install. Worked perfectly. Mu aeroponic garden doesnt leak a drop.

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