About this item

  • WATER TIGHT Rubber Grommets: in connections of DIY hydroponic systems, dutch buckets, dripping systems, siphon aquaponic systems and irrigation systems…
  • LEAK-FREE SEAL: Donut-shaped Rubber Grommets help transfer water or nutrient solution from one reservoir to another one with tubing and barded fittings or piping and 1/2 Inch Vinyl Tubing
  • DURABLE: periodically replace worn old ones in existing dripping or hydroponic systems to ensure air and water tight seals in your systems
  • It goes with barded connector fittings; then, connector goes with Vinyl tubing, hose or poly drip line of same size
  • The inner diameter of rubber grommet is 1/2 inch but the drilled hole on the bucket it fits into will need to be 13/16 inch~7/8 Inch


Drill the right size hole on the reservoir and push rubber grommet in; then, insert the pipe or connectors.

Be sure grommet's groove is fully inserted into the drilled hole.

If you have trouble with connection, please use soap or oil on the Barbed Elbow, Barbed Tee, Barbed Straight, Barbed Y Connector or PVC pipe to slide through drilled hole on the bucket or tank easier.

Said fits 1/2" pipe for hydro systems (Dutch buckets) but didn't.Ended up using copper pipe instead.... tight fit but got it done.

The grommets worked as advertised. I used them in my hydroponic setup to put the drain in the 3" pvc pipe I used for my net cups. After drilling the proper sized hole . I inserted them with a twisting motion and was able to install my small drain line for the return of the fluid to the fluid tank.Would buy again when needed.

This is a great product. It made setting up a flow thru hydro system so easy to construct. Just drill a whole in a pail, insert the grommet, the barbed connector and attach the hose. Simple and very cost effective.

I took another reviews suggestion and got a 3/4 inch bit. I used a hole saw. Another reviewer mentioned a 13/16 bit would work too but I just went with the 3/4 and it worked just fine. This is a small tote for the record.
