Black 40# H-shaped Automotive Rubber Seal

Black 40# H-shaped Automotive Rubber Seal is the largest H-profile in the range, a heavy-duty all-black edge seal built to straddle wide sheet metal flanges and heavy commercial door frames. Its substantial H-shaped cross-section wraps over the panel edge, with robust flexible lips on both faces that compress firmly against the mating surface to deliver a strong dual-sided weather seal while shielding the metal edge from corrosion and sharp edges.

This 40# size is engineered for the heaviest door systems on box trucks, shipping containers, refrigerated truck and reefer units, and large passenger or commercial vehicles with thick frames. The all-black finish hides dirt, scuffs, and wear in demanding operating environments, making it a practical choice for fleets and industrial equipment where appearance takes a back seat to durability.

Extruded from heavy-duty EPDM rubber, this black H-shaped seal offers outstanding resistance to weather, ozone, UV radiation, and wide temperature swings. It grips the thick flange securely without adhesive, rebounds after repeated heavy door closures, and provides dependable protection against rain, wind, dust, and road noise.

- H-profile that clips over wide panel edges for dual-sided sealing

- Largest 40# size for the heaviest commercial door frames
