Wide Applications of Rubber Sealing Strip
Window Seal & Door Seal Strip
A sealing strip is necessary for sound insulation, wind protection, or dust and insect protection. Whether it is door seal strips or window sealing, they are made of durable rubber or PVC. It can help our customers solve problems quickly.
Car Window Seal & Car Door Seal
A car door rubber seal can be soundproof, leak-proof, and weatherproof, improving driving safety. A durable car window seal provides high protection for your car.
Seal Strip For Rail Vehicle
A marine weather strip with good aging resistance is critical. Seals are rarely replaced frequently. Good oxidation resistance helps to improve the service life of the sealing strip. Even after long-term use, it can ensure a good use effect.
