What Are You Looking For?
Sliding windows are widely used in trucks and buses for ventilation, driver communication, and passenger comfort. However, without a high-quality sealing system, sliding glass panels can create noise, leaks, vibration, and premature wear. A flocked U-channel window sealing strip is the ideal solution for ensuring smooth movement and long-term durability.
This sealing strip is designed in a U-shaped profile that firmly grips the metal or aluminum window frame. The inner surface is lined with a soft flocked (felt-like) layer, allowing the glass to slide smoothly along the track while maintaining excellent sealing performance.
1. Smooth Glass Sliding
The flocked inner lining reduces friction between the glass and the rubber channel. This ensures:
Effortless opening and closing
Reduced wear on glass edges
Less operational noise
2. Excellent Sealing Performance
The U-shaped rubber structure tightly fits the frame, providing:
Strong wind and water resistance
Effective dust protection
Improved sound insulation
3. Durable & Weather-Resistant
Made from high-quality rubber (such as EPDM or PVC), the seal offers:
UV resistance
Aging resistance
Temperature resistance (both high and low climates)
Long service life in outdoor environments
This type of sealing strip is widely used for:
Heavy-duty trucks
Commercial vehicles
Intercity and city buses
Construction and special-purpose vehicles
It is especially suitable for sliding side windows and rear windows where smooth track movement is required.
Compared to standard rubber seals, the flocked U-channel design not only improves sealing performance but also enhances the user experience. Drivers and passengers can open and close windows easily without sticking or scratching sounds. At the same time, the improved sealing helps maintain cabin comfort by blocking wind, rain, and dust.
If you are looking for a reliable sliding window sealing solution for trucks or buses, the flocked U-channel window seal is a professional and durable choice that combines smooth operation, strong sealing, and long-term reliability.
