The inside diameter of each grommet is 3/8”. The rubber grommets are weather-resistant. They will not easily crack or tear.

Moreover, these rubber grommets easily snap into the pre-drilled holes and have water and air-tight seals.

If you have any issue with the connection, use oil or soap on the barbed tee, barbed straight, barbed Y connector, barbed elbow, or PVC pipe to easily slide via the drilled hole on the tank.
