The door sealing strips on box trucks play a critical role in ensuring performance, safety, and cargo protection.
- Thermal insulation
Door sealing strips prevent the exchange of hot and cold air between the inside and outside of the truck body, helping maintain a stable internal temperature—especially important for refrigerated and insulated box trucks.
- Waterproofing and moisture protection
They block rainwater, splashes, and moisture from entering the cargo compartment, protecting goods from water damage and preventing corrosion or mold.
- Dust and contaminant sealing
Sealing strips keep out dust, dirt, insects, and other contaminants, ensuring a clean cargo environment, which is essential for food, pharmaceutical, and hygienic transport.
- Improved airtightness
By enhancing the airtight seal around the doors, they reduce air leakage, improve refrigeration efficiency, and lower energy consumption of the cooling unit.
- Noise and vibration reduction
Door seals absorb vibrations and reduce rattling during driving, minimizing noise and helping protect cargo from impact damage.
- Structural protection and durability
Sealing strips cushion the contact between doors and the truck body, reducing wear on hinges, locks, and door frames, thereby extending the service life of the vehicle.
How to choose the right door seals for your vehicle body project?

Refrigerated Body Door Seals
For refrigerated truck door manufacturing, multi-lip EPDM compression sealing strips are often the more ideal choice because they offer better durability, long-term elasticity, and stable sealing performance under frequent door opening and closing conditions.

Dry Cargo Body Door Seals
This product adopts a composite structure of PVC plastic skeleton and EPDM elastic rubber, which has both good structural support performance and excellent sealing performance, and is widely used in the manufacturing of various commercial vehicle bodies.
