Product Specification

Car door seal is an important part of the car. Its main functions are sound insulation, noise reduction, waterproof and dustproof, shock absorption and buffering, and beautiful decoration，such as,

Door frame seal: installed around the door frame, it is the most important sealing component on the car door, which plays the role of sealing the gap between the door and the body, effectively blocking wind, rain, dust and noise.

Car door head seal: usually located on the inside of the door, close to the window glass, mainly used to enhance the sealing performance of the door, especially when the window glass is closed, it fits tightly with the glass to further improve the sound insulation, dustproof and waterproof effects.

Window guide groove seal: installed in the window guide groove of the car door, the function is to guide the lifting and lowering of the window glass, while ensuring the sealing between the glass and the guide groove, preventing rainwater, dust, etc. from entering the car.

Inner and outer strips: The outer strip is generally installed on the outside of the car door, below the window glass, mainly for decoration and waterproofing, to prevent rainwater from flowing along the window glass to the bottom of the door; the inner strip is installed on the inside of the door, below the window glass, mainly for sealing and sound insulation.

Door seals are usually made of EPDM, which has good elasticity and resistance to compression deformation, aging, ozone, and chemical effects. It has a wide range of applicable temperatures (-40℃~+120℃) and will not crack or deform after long-term use. The section shape varies depending on the car model, but generally it adopts a form that can effectively fill the gap. It is generally made of a composite of dense rubber and foam sponge rubber, and contains a unique metal clamp, which is durable and easy to install.
