2 angles This valve extension group has 2 angles, 90 degrees and 135 degrees. It adopts anticorrosive solid brass and metal dust cover, which is sturdy and durable. General purpose This tire extension is suitable for all passenger cars, trucks, motorcycles, trailers, motorhomes and motorhomes with standard tire valves. Angle design Successfully solved the following problem: Due to insufficient space between the valve and the wheel spokes, it is impossible to use the foot pump to check the tire pressure or to inflate the tire. Easy to install Built-in core allows inflation and deflation. You have just removed the existing valve cover and screw-in adapter. The bottom of the extension rod can be rotated freely for easy installation. Packaging 4 tire valve connectors (2 x 90 tire valve extensions, 2 x 135 tire valve extensions).
