> 3 dayI 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.
