General HydroponicsGrommet for AeroFlo 20/30 Reservoir Drain, 1/2 Inch, Bag of 25

Good product, great price crucial component of any deep water culture system. I drilled 7/8" holes near the bottom of 10- 5 gallon buckets, lightly de burred the holes with 220grit sandpaper installed and have had not one drip. Will be buying more in a few months.

Grommets are good, I add a little silicon adhisive to make sure the seal is water tight

These are well made. Glad I got these instead of the generic ones.

Very good

Great product and great price.
