Black & White 55# Multi-lip Automotive Weatherstrip

Black & White 55# Multi-lip Automotive Weatherstrip is a mid-large, dual-tone rubber sealing strip engineered for fleet and logistics operators who need a rugged, long-lasting door seal that stays looking clean and professional. The black sealing surface combined with a crisp white base foot delivers a sharp two-tone finish that disguises everyday road grime, tire dust, and minor wear far better than an all-black strip, while still suiting the utilitarian look of commercial box trucks and container bodies. At 55# size, it offers more sealing volume than compact 40# profiles but remains lighter and easier to handle than the bulky 80# multi-lip seal.

This 55# multi-lip weatherstrip is designed for box truck rear doors, shipping container doors, refrigerated truck and reefer unit doors, as well as larger passenger vehicle and van doors. Its series of staggered flexible lips compresses progressively as the door shuts, building up sealing pressure gradually rather than slamming shut with a hard single contact. That staged design reduces door-close effort, cuts cab and cargo area noise, and provides redundant protection: if one lip wears slightly over time, the remaining lips continue to keep out rain, wind-blown dust, exhaust, and cold air. For refrigerated vehicles, the multi-chamber profile helps insulate the door perimeter and maintain stable interior temperatures, reducing compressor cycling and fuel consumption.

Extruded from durable EPDM rubber compound, the 55# Black & White multi-lip strip withstands ozone exposure, UV radiation, and wide temperature swings from sub-zero reefer holds to summer asphalt parking lots. The rigid white base channels into the existing door groove for a secure, glue-free installation, while the soft black fins flex smoothly through hundreds of thousands of open-and-close cycles per year. The contrast between black fins and white carrier also helps installers verify at a glance that the seal is fully seated and not twisted during fitting, which is a small but valuable detail when outfitting a mixed fleet of box trucks, containers, refrigerated vehicles, and passenger vans.

Whether you are resealing a delivery box truck after a repaint, refurbishing an intermodal container door, upgrading a refrigerated truck's weather barrier, or replacing worn OEM weatherstrip on a passenger car or van, the Black & White 55# Multi-lip Automotive Weatherstrip delivers a balance of multi-stage sealing performance, durable EPDM construction, and a professional two-tone appearance that holds up in daily commercial service.
