4mm Top Hat Grommet - 20 Pack

  • $15.00
Tax included.


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.
