The Compressor Adapter allows you to inflate or top off your tube using a standard bicycle tire pump or air compressor. The Compresser Adapter only fits on the screw-on type valves like the boston valve (aka speed valve) or multi-valve. The Compressor Adapter is not for use on push-in style valves like the Speed Safety valve, over-sized safety valve, or safety valve. Consult your product user manual to see what kind of valve your product uses.
