Hydro Flow® Top Hat Grommets
Hydro Flow Top Hat Grommet 1/4 in (10/Bag)
These grommets can be used to replace old, worn top hat grommets in your hydroponic system and can be a valuable solution when building your own garden system. Top Hat grommets have a straight side wall for easy installation. When the fitting is inserted into the grommet, the wall is pushed against the whole surface to create the seal.
