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

Great product and seller!

Using the to create self watering planters out of 5 gallon containers. They do the trick.

Happy with product

The best Grommets Ive used for a water tight seal

Does not fit 1/2 pipe

The inside hole (id) is 1/2 diameter...it will not fit inside of a 1/2 hole (which would be OD of 1/2) Bamboozled again!

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

Quality

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!

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.
