Description

The Top Hat Grommet 16mm is a precision-moulded rubber top hat grommet designed for creating clean, professional seals around holes in grow tent walls, equipment panels, and hydroponic enclosures. Requiring a 19mm hole, the grommet’s flanged ‘top hat’ profile grips both sides of the panel wall, preventing fraying and delivering a tidy, secure seal wherever cables, tubing, or sensor leads need to pass through.

Widely used in grow tent builds, hydroponic systems, and DIY irrigation setups, these grommets are an inexpensive but essential component for keeping installations neat and preventing light leaks or moisture ingress around penetration points.
