Grow1 3/8-in Circle Grommet - 25 Count

Snug Tubing Entry Points for Hydroponic Lines - 25 Grommets

Tubing that passes through a reservoir wall or tray often leaks, shifts or chafes on a raw edge. These rubber circle grommets line the opening, hold the tubing in place and protect it from rubbing. Each unit contains 25 pieces, so you can finish a whole build without reordering.

With 25 pieces per unit, this is a practical size for a home grower fitting out one or two systems and for a commercial grower who wants spares on hand for repairs and expansion.
