Grow1 1/2 in Top Hat Grommet - Rubber - 25 Count

Cleaner Fittings for Hydroponic and Irrigation Lines - 25 Grommets

A bare hole in a reservoir, tray or lid lets light in, lets debris in and can chafe the tubing that passes through it. A rubber top hat grommet lines the opening, holds the fitting in place and gives the line a cushioned entry. The 1/2 in size is made for that job in hydroponic and irrigation setups.

This unit holds 25 grommets, which suits a grower building or rebuilding a single system, replacing worn fittings, or keeping spares on hand. Growers running several systems can order multiple units.

Key Features & Benefits

• Rubber construction — flexible material that grips the opening and protects tubing.
• Top hat profile — a flanged shape that helps keep the grommet seated in the opening.
• 1/2 in size — matches 1/2 in openings in hydroponic and irrigation builds.
• 25 grommets per unit — enough to outfit a full system or stock spares.

Who Should Use Grow1 1/2 in Top Hat Grommets

Home gardeners and licensed commercial growers who assemble hydroponic systems, drip lines or reservoir plumbing will find these useful wherever a line must pass through a drilled opening.

Frequently Asked Questions

Q: How many grommets come in one unit?
A: Each unit contains 25 grommets. You order one unit to receive all 25.

Q: What are these grommets made of?
A: They are made of rubber. This gives them flexibility to seat in an opening and cushion the line passing through.

Q: What does top hat mean?
A: A top hat grommet has a raised body with a flange around the top edge, like the brim of a hat. The flange rests against the surface and keeps the grommet from slipping through the opening.

Q: What are they used for?
A: They line openings where tubing or fittings pass through reservoirs, trays or lids. This helps protect the line from rubbing against the edge of the hole.

Q: Can I use them in irrigation as well as hydroponics?
A: Yes. They are intended for both hydroponic and irrigation applications. Check that your opening matches the 1/2 in size before drilling.
