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

Great quality. Better than the home depot grommets.

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.

quality made product.

These arrived on the estimated timr but ensure to take note of the sizing as this definity does not fit half (1/2) inch pipe as half inch pvc is the diameter of the whole grommet i would give it a 2.5 stars but it doesnt allow so 3 is fine as i misunderstood rather than false advertisement.

too small needed much bigger

Well made and does the job on hydroponic Dutch buckets.

Perfect for DIY hydroponic! Very similar to the ones used in General Hydroponic water farm!

perfect fit had no problems no water leaks . would buy again if needed .

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

Great for your in home needs very well made
