Black & White 40# Multi-lip Automotive Weatherstrip is a precision-extruded sealing strip engineered with multiple independent sealing lips along its length. This multi-lip design creates several staggered barriers that trap air and water between each lip, delivering significantly better wind, water, and noise isolation than a single-bulb seal. The 40# size is a versatile, medium-large profile suited to a wide range of vehicle door gaps.
This multi-lip weatherstrip is widely specified on box truck doors, shipping container doors, refrigerated truck and reefer doors, and passenger car doors where a quiet, dry cabin is a priority. As each lip compresses against the door panel, it forms multiple sealing lines that block driving rain, wind-driven dust, exhaust fumes, and road noise more effectively than a simple single-seal profile.
Extruded from weather-resistant EPDM rubber, this black-and-white multi-lip strip offers excellent ozone, UV, and temperature resistance. The multiple flexing lips retain their memory through millions of door cycles, while the rigid base keeps the strip anchored in the mounting channel. The black-and-white two-tone finish also makes the sealing edge easy to inspect during installation and maintenance.
Key benefits of the Black & White 40# multi-lip seal:
- Multi-lip design for layered wind, water, and noise protection
- Medium-large 40# profile fitting many standard door gaps
- Black-and-white contrast for visible installation and inspection
- EPDM construction with long weather and ozone service life
- Superior noise reduction and dust sealing for truck, container, reefer, and car doors
When a door needs more than a basic seal and demands a quiet, comfortable, weatherproof interior, this Black & White 40# Multi-lip Automotive Weatherstrip is an excellent choice. Contact us for profile drawings, custom lengths, and OEM supply.
