Grow1 1/2-in Circle Grommet - Rubber - 25 Count

Cleaner Fitting Openings for Hydroponic and Irrigation Lines - 25 Count

Bare holes in reservoirs, trays and lids can chafe tubing and leave rough, leaky gaps. These rubber circle grommets line the opening so lines pass through with a cushioned, tidy fit. Each unit contains 25 grommets in a 1/2-in circle size.

With 25 pieces per unit, this pack suits hobbyists building a first system and regular indoor growers who need spares for repairs and expansions. Larger operations can order several units to cover multiple reservoirs or tray runs.

Frequently Asked Questions

Q: How many grommets come in one unit?
A: Each unit contains 25 grommets. You buy one unit at a time, and it holds the full 25 pieces.

Q: What are the grommets made of?
A: They are made of rubber. Rubber flexes to seat in an opening and cushions whatever passes through it.

Q: What is a grommet used for in a hydroponic system?
A: A grommet is a ring that lines a drilled hole. It protects tubing or lines from sharp edges and helps the fitting sit neatly in the opening.

Q: How do I install one?
A: Drill or cut an opening that matches the grommet size, then press the grommet into it until it seats. Pass your line through the center afterward.

Q: Are these only for hydroponic setups?
A: They are intended for hydroponic and irrigation uses. Any similar pass-through that fits the 1/2-in size may work, so check your opening before buying.
