Potami 13mm Top Hat Grommet (16mm hole)
- 2 grommets per pack
- These top hat grommets are used in the water gauge hole for all Mr Stacky Smart Farm Reservoirs.
- The rubber grommets fit inside a 16mm hole to create a 13mm hole for use with standard 13mm poly fittings
- Made from flexible yet strong rubber to ensure a lasting seal with no leaking assuming the poly fitting is pushed sufficiently into the grommet.
