Features: The tire valves extension joint is made of brass with high wear resistance. Prevent Airs Leakage: Be sure to tighten the threads and sealing cap when using, the adapter screws onto your tire valves, and the right-angle bend allows for easy access for the pump or airs line to achieve the better-seals and ensure airtightness. This valves stem extension successfully solves a series of operations such as inability to pump or check airs pressure due to insufficient space between the valves and the spokes, or inconvenient valves position and angle. Easy to Operate: The bottom of the extension piece rotates freely, which is easy to operate, convenient and efficient. Widely used: Suitable for most bikes, motorcycles, strollers, trailers, RV and recreational vehicles, these valves extenders provide a practical solution for a wide variety of vehicles.
