Grow1 3/4 in Top Hat Grommet - 25 Count

Clean Pass-Throughs for Tubing and Fittings - 25 Count

Bare holes in reservoirs and trays let light in, invite debris and leave fittings loose. A rubber top hat grommet lines the opening, grips the fitting and keeps the connection tidy. These Grow1 grommets are made of rubber and fit a 3/4 in opening.

Sold as a single unit containing 25 grommets, this set suits growers building or maintaining several connection points at once, from a small hydroponic system to a larger multi-reservoir setup.
