• The Alligator Double Seal Valve Cap V2B is screwed on instead of the original valve cap and doesn’t need to be removed to check air pressure or to add air
• Gauging and inflating happen directly through the valve cap
• Fits all standard valves
• Its service is as long as that of the valve itself — no replacement necessary
• Double Seal Valve Cap has two built-in heat resistant grommets — preventing air pressure loss even when the valve core is damaged or dirty
• Clip-on air chucks hold more reliably due to the grooved surface
• The completely sealed end face is dirt and water repellent
