Clear, unobstructed visibility is paramount for safe and confident driving, especially when maneuvering in tight spaces or heavy traffic. The WG16642350003 CORNER WINDOW GLASS (HOWO) from HOWO is engineered to provide exceptional optical clarity, shatter resistance, and a precise factory fit, restoring the original look and functionality of your vehicle’s side glazing. As an essential Howo/Sitrak truck parts component, this corner window glass is manufactured from high‑quality tempered safety glass, meeting stringent ECE R43 standards for impact resistance and UV protection. Its precision‑curved shape matches the original cabin contour, ensuring a flush, weather‑tight seal with the existing rubber molding. Whether you are replacing a cracked, chipped, or scratched pane, the WG16642350003 delivers factory‑grade optics, lasting durability, and easy installation – making it the trusted choice for professional body shops and fleet maintenance teams worldwide.
The WG16642350003 Corner Window Glass is not just a pane of glass – it is a key safety and comfort element that contributes to the structural integrity of the cab and provides crucial visibility for monitoring blind spots and traffic. A damaged or cloudy corner glass can obstruct the driver’s view, increase glare, and compromise the cab’s insulation against noise and temperature extremes. HOWO has designed this glass with a precisely controlled curvature and thickness, ensuring that it fits perfectly into the window frame without stressing the seals or causing wind noise. The tempered glass construction ensures that, in the event of a break, it shatters into small, blunt granules rather than sharp shards, significantly reducing the risk of injury. With the WG16642350003, you restore both the safety and aesthetic appeal of your HOWO truck’s cabin.

The WG16642350003 is produced using advanced glass forming and tempering technology. The raw glass is first cut to shape from high‑quality float glass, then edge‑ground to eliminate stress risers. It is then heated to approximately 620°C and rapidly cooled using high‑pressure air, creating a compressed surface layer and a tensioned core that gives tempered glass its characteristic strength – up to four times stronger than standard annealed glass.
The glass is then bent to the precise curvature of the corner window frame using a gravity or press‑bending process, ensuring a perfect match to the original cabin contour. A protective UV‑absorbing interlayer is applied to reduce solar glare and protect interior upholstery from fading. The edge finish is smooth and consistent, allowing for a proper seal with the rubber gasket without causing leaks or wind noise. Each pane is inspected for optical distortion, chips, and bubbles, guaranteeing that the WG16642350003 provides a clear, unobstructed view and a flawless appearance.
The WG16642350003 is specifically designed for HOWO heavy‑duty trucks, including T7H, A7, and derivative models. It fits the corner window aperture on the driver or passenger side, directly replacing the original glass. The dimensions and curvature match the factory spec, ensuring a flush, weather‑tight fit when installed with the correct rubber seal.
This glass is also compatible with many Sinotruk and other commercial vehicles that share the same cabin design. To confirm fitment, always cross‑reference the OEM number on your existing glass with WG16642350003. If they match, this component will integrate seamlessly. Keeping this glass in your spare parts inventory allows for rapid replacement of cracked or damaged panes, preserving cabin integrity and driver visibility.

Replacing a damaged or weathered corner window with the WG16642350003 immediately improves cabin visibility and aesthetics. The optical clarity reduces eye strain and enhances the driver’s ability to perceive surrounding traffic, pedestrians, and obstacles, particularly in low‑light conditions. The UV‑blocking coating reduces solar heat gain, keeping the cabin cooler and reducing the load on the air conditioning system.
The precise fit and correct thickness also restore the original sound insulation, reducing wind and road noise for a quieter, more comfortable ride. For fleet operators, a clear, undamaged glass pane enhances the professional appearance of the vehicle and helps retain resale value. By investing in the WG16642350003, you ensure that your truck not only looks great but also provides the safety and comfort that drivers deserve.
Installing the WG16642350003 Corner Window Glass is a straightforward task for a skilled technician. Begin by removing the old glass by carefully cutting the sealant or prying the rubber gasket, taking care not to damage the surrounding paintwork. Clean the window aperture thoroughly, removing all old adhesive, rust, or debris.
If the rubber seal is worn or brittle, replace it with a new one. Apply a bead of high‑quality glass adhesive (urethane) to the seal or frame, following the manufacturer’s instructions. Carefully position the new glass into the aperture, pressing it evenly to ensure full contact. Use tape or suction cups to hold it in place while the adhesive cures, typically for 24 hours. After curing, check for water leaks by spraying water over the window. Avoid washing the vehicle with high‑pressure water for the first 48 hours. With proper installation, the WG16642350003 will provide a lasting, watertight seal.
Pro Tip: When installing, always use the recommended glass primer and adhesive to ensure a strong bond. The WG16642350003 is designed to work with standard automotive glass adhesives; follow the adhesive manufacturer’s cure time for best results.
Genuine HOWO components are engineered to the highest standards, and the WG16642350003 Corner Window Glass is no exception. Aftermarket glass often has inconsistent curvature, lower clarity, or insufficient tempering, leading to poor fit, distortion, and increased risk of breakage. HOWO’s glass is manufactured using the same tooling and quality controls as the original equipment, guaranteeing a perfect fit and reliable safety.
By choosing the WG16642350003, you benefit from HOWO’s rigorous testing, including impact resistance, optical quality, and thermal stress validation. This ensures that the glass meets all regulatory safety standards and provides a clear, distortion‑free view. Moreover, genuine parts are backed by a comprehensive warranty and supported by HOWO’s global network, giving you confidence in your purchase.
