Green & White 40# Multi-lip Automotive Weatherstrip

Green & White 40# Multi-lip Automotive Weatherstrip is a twin-color, multi-fin rubber seal designed to deliver dependable all-weather performance while remaining clearly visible during installation and maintenance. The bright green sealing lip contrasts against the white base carrier, giving technicians an immediate visual cue that the seal is correctly seated and fully compressed around the door perimeter. At 40# size, it hits the sweet spot between compact 15–20# strips and bulky 80# profiles, making it a versatile middle-ground option that fits a wide range of standard door groove widths without looking oversized.

Engineered for box truck doors, intermodal shipping container doors, refrigerated truck and reefer doors, as well as passenger car and light commercial vehicle doors, this multi-lip strip stacks several flexible sealing fins along its length. When the door closes, each fin deflects independently, creating a series of trapped air chambers that act as progressive barriers against wind, rain, snow, road dust, exhaust gases, and traffic noise. The staged compression means the seal performs even on slightly bowed door panels or frames that have shifted after years of operation, which is especially valuable on older box trucks and used containers where a single-bulb seal would already be leaking.

The green-and-white colorway also serves as a practical maintenance indicator: because the green sealing surface is easy to spot against most door interiors, fleet supervisors and repair crews can quickly inspect seal condition during routine yard checks, spot cracked or dislodged fins, and schedule replacement before water ingress damages cargo or interior trim. Manufactured from high-grade EPDM rubber, the 40# multi-lip compound offers proven resistance to ozone, UV sunlight, temperature extremes, and repeated slam cycles. It stays flexible in winter cold and does not soften, bulge, or stick in summer heat, maintaining consistent sealing pressure over a long service life.

Whether used as original-equipment replacement on passenger car doors, as a retrofit upgrade for box truck and container door weather seals, or as a temperature-stable gasket for refrigerated truck doors, the Green & White 40# Multi-lip Automotive Weatherstrip combines multi-stage sealing efficiency, visual inspection convenience, and durable EPDM construction in one practical, cost-effective profile.
