Product Introduction 5301112LE010 Cowl Panel Seal is a weatherproof rubber sealing strip installed at the cowl panel of HFCN721 JAC light truck, positioned between hood and windshield base. It blocks rainwater, dust, leaves and debris from entering the cowl cavity and cabin air intake, while suppressing wind noise during high-speed driving. This aftermarket replacement seal solves water leakage, increased wind roar and debris clogging caused by rubber aging, cracking, hardening and shrinkage of original cowl seals, protecting wiper assembly, cabin ventilation system and internal wiring for urban logistics light cargo vehicles.

Product Advantages Made of premium EPDM rubber with outstanding UV resistance, ozone resistance and elasticity under temperature fluctuation. Stable sealing performance without easy hardening or cracking under long-term outdoor exposure. Precision molded profile perfectly matches the cowl panel contour. Each seal undergoes aging and compression testing before shipment, simple installation and effectively reduces water ingress and wind noise inside cab.

Applicable Models Fit for JAC HFCN721 light truck series, matches the original cowl panel mounting structure for urban cargo delivery and short-distance logistics vehicles.
