Need help identifying and sourcing grommet

I bought the OxygenPot XL Ebb&Flow system

After multiple uses the grommets have become quite worn, and OxygenPot seems to have vanished.

I've looked at quite a few other grommets and can't seem to find some that are as thick and stay as rigid.

They were absolute hell pulling them out which caused the wear and tear, but they never leaked a bit, and you could grab the line attached to all six buckets and do jump rope and they wouldn't move.

Any suggestions on where to find these? Or something similar?

I think I can use the Active Aqua, or maybe the HydroFarm 3/4" grommets if I can't find these, just figured i'd ask

After rebuilding my room again I decided to use pvc with unions between every plant so I can easily unscrew and move them.

Thanks

Try Grainger.

I would measure the hole it fits and grab a uniseal, looks like a take on a type of jobber uniseal.

All that should matter is the ID and OD measurements.
