This Wilwood brake line grommet seal is specified for a 5/8-inch hole with a 3/8-inch inner diameter and serves as a replacement grommet where a snug seal around a brake line or fitting is required. It provides a sealed pass-through to help prevent fluid or debris intrusion at the firewall or mounting bulkhead. Fit it when replacing or routing brake lines through panels that match these dimensions.
