Mitsubishi Rear Door Opening Lower Outer Weatherstrip Seal
Keep your cabin quiet, dry, and clean with this OEM-grade rear door opening lower outer seal. Designed for Mitsubishi crossovers, it closes the gap at the sill edge so the door compresses evenly against soft rubber, blocking water, dust, and road noise. Perfect for restoring factory comfort and protecting the rocker area from corrosion.
Why you need it ✅
Over time, rubber hardens, cracks, or tears from sun, salt, and door friction. A fresh seal maintains proper door compression, reduces wind noise, and prevents wet carpets and musty odors. It also shields paint at the threshold from chafing.
How it works
Made from EPDM rubber with molded corners and precise clips, it forms a continuous barrier along the lower door opening. When the door shuts, the bulb profile compresses, creating an elastic seal and channeling water away from the interior.
If the seal is damaged ⚠️
Expect whistles at speed, water intrusion after rain, dirt tracks on the sill, rattles, and faster rust on the rocker seam. Prolonged leaks can affect carpets, wiring connectors, and cabin air quality.
Tech tip ️
Clean the pinch weld, press clips evenly, avoid stretching the rubber, and lightly talc the seal to prevent sticking. Test with a hose and a short drive.
