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

Its so easy using this product. Drill the proper size hole and insert it in and seat it right and presto, a leak proof seal for using barbed connectors.

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.

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

Exactly what I needed. Worked just as expected.

Well made and does the job on hydroponic Dutch buckets.

A +

Package the grommets were in was not sealed. Missing some

They work great for sealing houses in buckets for hydroponics.

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.

Very good quality and will buy again when needed.
