Seals-It patented firewall grommets are a nitrile rubber material bonded to an aluminum bezel. They're designed to stretch to allow a fitting to pass through, and yet will grip hose to keep debris out. These grommet seals are great for wiring, fuel and oil lines, air and liquid hoses, and other types of lines. And, they can be used for other applications, including race cars, custom cars, marine, commercial equipment, motor homes, and much more. Order the inside/outside diameters needed for your vehicle.
