Grommets are used to create watertight seals for the plumbing of hydroponic systems such as NFT systems, DWC systems, Dutch Bucket systems, water reservoirs etc.
A hole is drilled and the Grommet is inserted into the hole. Piping is then pushed through the grommet which will form a watertight seal.
The following grommet & piping combinations are advised:
