Black & White 80# Multi-lip Automotive Weatherstrip

Black & White 80# Multi-lip Automotive Weatherstrip is the largest and most robust profile in the multi-lip family, engineered for heavy-duty door openings where maximum sealing volume and long service life are non-negotiable. With its wide multi-fin construction and a black-and-white dual-tone finish, this 80# strip delivers aggressive compression across broad door gaps while keeping a clean, industrial look on the bodywork. It is the preferred choice for fleet operators, container conversion specialists, and refrigerated transport professionals who need a seal that can stand up to the harshest weather and the highest daily door-cycle counts.

This oversized 80# multi-lip weatherstrip is specifically specified for box truck rear doors, shipping container doors and frames, refrigerated truck and reefer unit doors, as well as large passenger vehicle and commercial van doors with wide perimeter gaps. The multiple stacked flexible lips compress in sequence when the door shuts, producing a series of independent sealing chambers that block wind, driving rain, snow, road dust, exhaust fumes, and traffic noise far more effectively than a single-bulb gasket. On refrigerated vehicles, the extra-wide profile also provides a thicker thermal barrier around the door, helping to maintain stable cold-chain temperatures and reduce the energy the refrigeration unit must consume.

The black sealing fins contrast sharply with the white rigid base, giving installers an unambiguous visual reference during fitting. Because the 80# profile is so wide, proper alignment matters more than on smaller sizes; the color contrast makes it easy to confirm that the seal is running straight, fully seated, and not twisted around corners or hinge pillars. Manufactured from premium EPDM compound, the strip resists ozone, UV aging, and temperature extremes, and it holds its shape through hundreds of thousands of open-and-close cycles per year. The rigid carrier clips or slides into the existing door channel without adhesive, while the soft black fins wear predictably and can be inspected quickly during routine fleet maintenance.

From hauling box trucks on long-haul highways and sealing intermodal containers in port yards, to maintaining cold air inside refrigerated reefer trailers and quieting the door perimeter of large passenger vans, the Black & White 80# Multi-lip Automotive Weatherstrip is built for demanding commercial duty. Its heavyweight multi-lip design, durable EPDM construction, and high-contrast two-tone finish make it a dependable, long-life sealing solution across box truck, container, refrigerated vehicle, and passenger car door applications.
