Inside dimension 3/4". The holesaw size is 1"(25mm). Grommets are commonly used when needing to transfer water from one container to another with tubing. Hydro Flow® Fender Grommets supply additional support on the front of the grommet, keeping the grommet from pushing through. The oversized front helps to keep grommet in place, while securing the fitting with a leak free seal.
