The Leafield Marine D7 valve is designed to replace the highly successful C7 Valve. The boots on the C7 & D7 are not inner changeable, meaning you must replace the entire valve.
The new D7 Valve has several benefits over the previous model, with improved inflation/deflation speed. It has an enhanced clamping method with an ‘O’ ring seal added to the valve core to reduce the risk of leaks. The D7 valve also has a shorter internal profile than the C7.
ACETAL (POM) plastic parts give high strength, chemical, and ozone resistance.
The seal is designed so that it cleans the sealing surface as it operates; this also reduces the risk of leakage due to dirt contamination.
When the cap is fitted, the rugged retaining strap is hidden from view to prevent snagging on other equipment. Simple cap replacement - it does not require the valve to be removed.
SOTAR transitioned from C7 valves to D7 February 20, 2015. Please contact us directly should you have questions on what valve you have.
