A high pressure monitor includes an outlet body with a transverse passage, which extends through the body to form two inlets of the outlet body, and a second passage, which is in communication with the transverse passage and extends through the outlet body to form an outlet. The monitor further includes first and second bodies, with the outlet body mounted between the first and second bodies. Each of the first and second bodies has a transverse passage, which are in fluid communication with the inlets of the outlet body. A first swivel joint is provided between the outlet body and the first body. A second swivel joint is provided between the outlet body and the second body. Further, each of the swivel joints comprises a pressure balanced hydraulic fitting with seals and bearings, wherein the seals and bearings are oriented to reduce the axial pressure on the bearings from fluid flowing through the monitor.

1. A fire-fighting monitor for directing the flow of fluid from a fluid source, said monitor comprising: a cylindrical pipe section adapted to mount said monitor to a fluid source; a monitor body having an inlet and an outlet, said inlet mounted on and supported by said cylindrical pipe section and for receiving fluid through said pipe section, said outlet in fluid communication with said inlet for discharging fluid from said monitor body; a rotatable connection between said inlet and said pipe section, said rotatable connection permitting said inlet to rotate about a first axis over a range of motion about said pipe section; a drive mechanism mounted to one of said pipe section and said monitor body and drivingly engaging the other of said pipe section and said monitor body for rotating said inlet about said pipe section about said first axis; and a control capable of receiving control signal commands, said control operably connected to said drive mechanism so that said control may provide control signals to said drive mechanism in response to receipt of radio control signal commands to control the rotation of said monitor body about said pipe section, and said control further adapted to cause said monitor body to rotate back and forth in oscillation between predetermined limits established electronically by said control. 2. The fire-fighting monitor according to claim 1, further comprising a remote transmitter apparatus, said remote transmitter apparatus including said transmitter, said remote transmitter apparatus being adapted to allow a user to adjust said predetermined limits. 3. The fire-fighting monitor according to claim 2, wherein said control further establishes maximum predetermined limits. 4. The fire-fighting monitor according to claim 3, wherein said maximum predetermined limits are only adjustable using said control and not by said remote transmitter apparatus. 5. The fire-fighting monitor according to claim 2, wherein said rotatable connection permits said inlet to rotate about said first axis over a range of motion extending at least 360 degrees about said pipe section. 6. The fire-fighting monitor according to claim 5, wherein said predetermined limits may be adjusted at the control. 7. The fire-fighting monitor according to claim 6, wherein said predetermined limits may be adjusted between any two positions in said range of motion. 8. The fire-fighting monitor according to claim 1, further comprising a housing mounted to said monitor body, said control being mounted in said housing. 9. The fire-fighting monitor according to claim 1, wherein said monitor body comprises an inlet pipe Section and an outlet pipe section rotatably mounted relative to said inlet pipe section about a second pivot axis, and said outlet pipe section including said outlet. 10. The fire-fighting monitor according to claim 9, further comprising a second drive mechanism for rotating said outlet pipe section about said second pivot axis. 11. The fire-fighting monitor according to claim 1, wherein said cylindrical pipe section includes an integral mounting flange extending radially outwardly from said cylindrical pipe section for mounting said monitor to a fire fighting fluid supply.
