Autopot Top Hat Grommets
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.
Top Hat Grommet measurements (approximate, in mm) follow below:
| 6mm Top Hat Grommet | 10 | 6 |
| 9mm Top Hat Grommet | 13.5 |
9 |
Based on the above the following grommet & piping combinations are advised:
9mm Autopot Piping (for use with Autopot Aquavalve 5): 9mm Top Hat Grommet
5mm irrigation piping: 6mm Ring Grommet or 6mm Top Hat Grommet
6mm Top Hat Grommet: 9.5mm drill bit
9mm Top Hat Grommet: 12.5mm drill bit
It is not recommended that Petroleum Jelly is used as a lubricant. A silicon lubricant, although more expensive, is better. Olive oil can also be used. Throwing grommets into HOT water before installing also helps a lot.
Please note if grommet is fitted and then taken out a number of times, it may stretch and warp.
