SPRAY HEAD Abstract of the Disclosure A spray head which is characterized by a tubular body with an axial bore divided into axially spaced sections of different diameter with the forward section, which is at the discharge end of the head, being of the largest diameter and constituting a chamber in which a spherical spray tip holder is mounted so as to be rotatably seated on the mating inner face of a remov- ably mounted end cap, which holder has a radial socket aligned with a cross bore in the body for receiving a turning member enabling rotation of the tip holder between an operative position for direction of spray material through a discharge aperture in the end cap and a cleaning position for reverse flow of material through the spray tip and a bearing and sealing assembly engaging the tip holder surface opposite its engagement with the end cap which assembly is arranged to minimize the pressure exerted on the tip holder by the spray material and possibly leakage of the product into the tip holder cham- bers, the latter being provided with a relief opening in the event there is a sealing failure,
