The rotating head nozzle is constructed completely in PTFE (Teflon). There are no bearings in this design, which alleviates the concern of dirt and other materials fouling the bearings and affecting the rotation of the head. The solid stream design of the spray allows for greater impact on the vessels surface. The connection is 1/2″ female in either NPT or BSP threads. The spray coverage options are 360 degree’s and 180 degree’s (up and down).
