Description

1/4″ Top Hat Grommet

Durable rubber grommets for all your mushroom, hydroponic and/or irrigation needs. These are direct replacement grommets for our Regular Mouth MycoLID™ and our Wide Mouth MycoLID™.  Use these to replace old ones on lids you purchased to save a bundle or use them to build your own and save even more!

This grommet is also used in our MycroGROW™ Kit for our custom made OxyFlow Continuous Airflow System. Great for bringing 3/16″ air tubing, also known as 1/4″ tubing as the OD is 1/4″, into any sealed chamber with a watertight seal. Simply drill a hole using any standard 3/8″ drill bit, press in the top hat grommet, and then feed the 1/4″ tubing through the grommet hole. Works great for hundreds of applications!
