The D7 Valve is a great addition to the Leafield line of quality valves. Its internal screen keeps things like stray drop-stitch threads from getting in the sealing surface.
Replacing the C7 valve in some instances, the D7 has an enhanced clamping surface that helps prevent leaks in high pressure inflatables.
The extremely durable acetal plastic parts are resistant to chemicals and ozone
Low-profile cap prevents snagging on other equipment and simple cap replacement doesn't require the valve to be removed.
The D7 valve has a shorter internal profile than other valves making it ideal for smaller diameter tubes.
