Aqua Gardening Suggests These are Best For

These Top Hat Rubber Grommets are ideal for gardeners, hydroponic enthusiasts, and anyone looking to create an efficient and reliable irrigation system. They are suitable for use in a variety of applications, including gardens, greenhouses, or indoor hydroponic systems.

Notes from Aqua Gardening

  • For enhanced leak protection, apply silicone around the rim of the grommet before inserting it into the hole.
  • If you encounter a hard rubber grommet, knead it in your hands to soften before inserting it into the hole and connecting the fitting.
  • Always use the recommended hole saw sizes for each grommet: 10mm for 6mm internal diameter, 16mm for 13mm internal diameter, and 22mm for 19mm internal diameter.


What is the purpose of a Top Hat Rubber Grommet in an irrigation system?

Top hat rubber grommets are used in conjunction with take-off fittings, tubing and barbed irrigation fittings to provide a seal around the fitting through a wall in a plastic container. This allows for a small diameter poly pipe branch from a large supply pipe, or a reservoir container of water or nutrient for a garden or series of pots.

What sizes of Top Hat Grommet are available at Aqua Gardening?

Aqua Gardening stocks Top Hat Grommets in the following sizes:

- 6mm internal diameter (use holesaw size 10mm)

- 13mm internal diameter (use holesaw size 16mm)

- 19mm internal diameter (use holesaw size 22mm)

How do I install a Top Hat Grommet in my irrigation system?

To install a Top Hat Grommet, follow these steps:

1. Drill a hole according to the corresponding holesaw size for your grommet.

2. Clean any burrs from the drilled hole.

3. Insert the top hat grommet into the hole.

4. Push the tube or barbed fitting through the grommet.

Are there any tips for ensuring a better seal with Top Hat Grommets?

Yes, for additional leak protection, we recommend applying some silicone around the rim of the grommet before inserting it into the hole. If you have a hard rubber grommet, knead the rubber in your hands before inserting it into the hole and connecting to it. This helps ensure a better seal and easier installation.
