Your cart is empty.These grommets can be used to replace old, worn top hat grommets in your hydroponic system and can be a valuable solution when building your own garden system. Top Hat grommets have a straight side wall for easy installation. When the fitting is inserted into the grommet, the wall is pushed against the whole surface to create the seal.

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

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.

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

good stuff, no leaks that I can see used in both galvanized cans and plastic.

Overpriced. This price should be for 100 pieces.

This price is a joke, should include at LEAST 20 for this price. But really 50 would seem reasonable.

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@!
