Hydro FlowTop Hat Grommet 1/4 Inch, Bag of 10

Some of my old ones were starting to break down and these were the perfect replacement

I used these with 6mm OD line for a gutter grow system. They worked great and no leaks. I did not have a 9mm drill bit to drill the holes in the 1 1/4 inch schedule 40 pvc supply line but used a conversion chart I found on line for a nearly equivalent English size and it's up and running. Very happy so far.

Works perfect. It's not rocket science, it's a grommet. But it'd been working and maintaining a water tight seal from heavy use for months

Good grommet for boat windshield fits a 1/4 inch hole ....

Sturdy

I didn't return in time but item is correct on dimensions

works well at keeping out light. Need to drill a slightly bigger hole to fit it but the tubing slide through ok. I will purchase more when I need them.

works as expected - great purchase!

For some reason all hydro flow parts are much smaller than your Normal 1/2inch by( life guard or active aqua or even just vs a normal grommet half inch) these are 2 small for a real 1/2 hole make 3/4th holes ignore your going to use these for levellers or DIY hydro if you need real top hat 1/2 inch then I know a brand just comment asking and I’ll let you know as I make my own kits with them and don’t want to give away my secrets for free lol but I will to those brave enough to DIY ! Enjoy have fun it’s a hobby not a job ! Just relax and water once every 2-3 days till run off and just daily for @medial tomaotes and evrry one calls them lol@!
