Grommet

Comes in 5/16, 1/2, 3/4 inch sizes

This sealing grommet works like a bulkhead fitting allowing the connection of 3/4" tubing to a tray or other container. Use the grommet to make a water tight seal in plastic material up to 1/8" thick. Drill a 1-1/16" hole and insert the grommet then push a 3/4" connector through the grommet. This part is essential for those of you who are building their own system.
