Precision Fit: Focused on vacuum tire compatibility needs, offering two mainstream models, TR43E and TR48E, to precisely match various specifications of vacuum tires and rim designs. The TR43E is a standard universal type, suitable for vacuum tires of common models such as family sedans and SUVs. The TR48E emphasizes enhanced compatibility, designed for vacuum tires of certain heavy-duty sedans, light trucks, and specialty vehicles, with a slightly larger sealing base diameter, making it suitable for thicker rims or high-load tire applications. Sealed Structure: Features a triple sealing design to prevent air leakage in tubeless tires at the source. After inflation, it automatically seals tightly, ensuring excellent air pressure retention. The valve stem and hub contact area is equipped with a thickened nitrile rubber sealing ring, which is heat-resistant and aging-resistant. It fits snugly against the hub mounting hole, preventing moisture and dust from seeping through gaps. High-Stre
