I am trying to find a special grommet. They are used on wiring harnesses to seal a small loom of wire passing thru a larger hole (larger hole for connectors to easily pass thru. They either seal tight to the loom or you tape/heat shrink tubing. I want something for about 3/8" diameter wiring and fit a 1" to 1 1/2" hole. (any in that size range, not able to fit both hole sizes listed) Hope that is clear. There are two on the harness pictured.
