EPIC Grommet

The EPIC Grommet is an injection-moulded silicone seal that carries the standard EPIC connector pipe through the wall of a pan, pan sheet, header pipe or chamber. It fits one drilled hole and is pressed home as a single part, with no solvent cement, no compression fittings and no second component to specify or store.

The first page shows the three places it seals. In pan and pan sheet walls it keeps the cell sand-tight while water passes freely between chambers. In the inlet and outlet headers it receives the connectors running to each row of chambers. In the end wall of the last chamber it takes the zero-drain outlet pipe used to adjust the saturated zone.

The second page is the specification table, with a dimensioned section through a sealed penetration. It covers material, outside diameter, height, drill-hole size, receiving groove, the range of wall thickness sealed, bore, pipe accepted, internal seal ridges, unit weight, packaging and minimum order, HS code and origin. The fitting sequence is set out in three moves, with a note on how to count grommets for an order.
