A rubber firewall grommet must match the specified passage through a vehicle firewall or panel. The profile may include an extended neck, but construction varies by product.
Provide the opening dimensions, panel thickness and cable or bundle size. Check the material for temperature and relevant fluids. Define any required fire, smoke or environmental seal rather than inferring it from the product name.
Custom manufacture is reviewed against a customer drawing or existing sample. Confirm feasibility, tooling, sampling and acceptance criteria before production. After installation, verify seating, cable clearance and the required passage performance.
