The Sports Stuff 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. Item # 10-1010
