48" long throttle control cable. This is commonly known as a "Bullwhip" and is produced by Conrader Valves and is made in the usa. This valve controls the engine throttle speed on gas-powered air compressors when used in conjunction with a pilot/unloader valve. This is the regular size valve that is used for compressors with gas engines up to 8hp. If your compressor has an engine larger than 8hp, you will need a large-size bullwhip which we also have listed in this category. This valve has 1/8" Npt male pipe threads that go into the unloader/pilot valve on the compressor.
