1-1/2" Inside Diameter (ID) Rubber Grommets

Every grommet on this page has a 1-1/2" inside diameter (ID), the clear opening left for whatever passes through it. A 1-1/2" opening is sized for a 1" PVC pipe, a thick hose, or a large bundle of cables passing through a bulkhead or enclosure wall. The 6 styles here fit panel holes of 1-3/4", with groove widths of 1/16", 1/8", 3/16", 1/4" and 3/8", so you can match both the hole you drilled and the thickness of the material.

How to size a 1-1/2" ID grommet. Start with the item going through: measure its outside diameter, or the widest point of any plug or fitting that has to pass, and make sure it clears 1-1/2". Next, measure the hole with calipers; the grommet should be listed as fitting that exact hole size, because the groove has to sit tight against the edge. Last, measure the panel thickness and choose a groove width equal to it or slightly wider. If the panel is thicker than the widest groove listed, drill to a larger hole size instead and step up in ID. Searching by hole size rather than opening? Use the "fits holes" link below.
