ABSTRACT OF THE DISCLOSURE A fluid set and spring released clutch according to the teachings of the present invention is shown as includ- ing a one-piece hub including a cylindrical portion having a first tapered hole portion for securement to a shaft and a second cylindrical hole portion for receiving a rotary air union. A radially extending flange portion terminating in an annular lip is formed on the cylindrical portion of the hub and forms an annular cavity for the reciprocal receipt of a piston. The clutch further includes a pulley rotatably re- ceived on the hub having a recess formed therein. An exten- sion integrally attached to the piston extends into the recess of the pulley for providing friction engagement therebetween. The piston is mounted by bolts threadably secured into the extension and reciprocally received in the annular lip of the hub. The piston is biased into the cavity by springs located between the piston and the hub. The rotary air union is in fluid communication with the cavity behind the piston and includes a base portion which is received in the cylindrical hole portion of the hub.
