Dick shape tyre valve dust caps Pink or Black set of 4 are great for a laugh and at the same time protect your valves from dirt,made from Rubber these are push on so can either be fitted directly over the valve or over the top of existing valve caps as long as they are narrow ones or standard plastic type push on hard and as far down as possible to ensure they stay in place.
Not suitable for Presta bike type valve as that type of valve is too narrow so would be too looser fit - please see i9mages as image 2 shows which type of valve for these which is stanfard car valve and bikes + that have the same type of valve.
length is approx 4.5 m as shown
Inside Diameter is approx 1 cm to snug fit a standard car type valve push on firmly
Please visit my eBay shop for many other types of valve caps + many other items most of which are ideal gift ideas.
