mil Kit Valve 1 Pair for use when you want to fit the system to multiple bikes but already have the injector. Available in 35, 45, 55 or 75 mm lengths for different depth rims. milkit's unique valve won't clog & does not release pressure when the core is removed so awkward tyres are easier to inflate & keep inflated; this also means a damaged valve, no longer means an end to your ride. The unique system also means that you can accurately check & top up sealant without removing the tyre, no more spills. Your tyres can also be changed without wasting sealant.
