Belt Weatherstrip - China
price: contact company for price
We are a manufacturer specializing in the design, development, and production of automotive sealing strips.
Belt Weatherstrips (also called belt-line moldings, door belt seals, or window belt weatherstrips) are rubber or plastic seal strips mounted along the belt-line of a car door, just below the window glass.
They form a crucial part of the vehicle’s sealing system, preventing water, dust, air, and noise from entering the cabin, stabilizing the window glass during its movement, and maintaining a clean, finished appearance for both interior and exterior.
Typically, each car door uses two belt weatherstrips:
Inner belt weatherstrip — along the inside beltline, providing sealing against water, dust and air ingress.
Outer belt molding / weatherstrip — along the exterior beltline, offering weatherproofing and often a decorative or trim finish (chrome bead, stainless-steel insert, or colored molding) depending on design requirements.

01 Effective Seal Against Water, Dust & Air
A well-designed beltline weatherstrip prevents rainwater, road dust, and external air from entering the interior, helping maintain cabin comfort and protecting interior components from moisture and debris.
02 Noise Reduction & Smooth Window Operation
With proper sealing and a flocked or soft-rubber surface, belt weatherstrips reduce wind noise when windows are open or closed, and ensure smooth up/down movement of the window glass without scratching or snagging.
03 Fit, Finish & Aesthetic Appeal
Outer belt moldings often incorporate styling elements — chrome or stainless-steel beads, color-matched rubber/plastic, or a flush design — enhancing exterior look while serving functional sealing purpose.
04 OEM / Aftermarket Replacement & Customization
Ready-made belt weatherstrip kits for older / classic vehicles (inner & outer belts per door)
