This 6 inch air hose extension uses a standard Schrader valve (male) for an input and a clip on air chuck for output. The air chuck output is designed to clip onto standard Schrader valves. Air chucks come standard with SuperFlow MV89 and SuperFlow MV90 model air compressors. All SuperFlow air compressors and air hoses may utilize this optional utility. Any compressor that uses a screw on fitting to attach to your tire’s Schrader valve will be able to accommodate this air chuck. Great for being able to quickly clip on/off the tire if you prefer not to use the EZ Twist brass inflation nozzles already attached to SuperFlow air hoses.
