ABSTRACT:
The invention in a safety bleed assembly includes a body wherein intersecting passages are formed that mount in ends thereof, respectively, a pressure gauge, and ports with check valves and ports alone. The ports with check valves function as high pressure ports and are for connection through lines or hoses to high pressure check/bleed connectors that have been mounted in lines or hoses of a section or sections of a hydraulic system that may remain under pressure after the hydraulic system has been shut down, and the ports without check valves function as low pressure ports that are for connection through lines or hoses to low pressure check/bleed connectors that have been mounted in lines or hoses of a section or sections of the hydraulic system that are at zero or low pressure when the hydraulic system has been shut down, with fluid passed through the safety bleed assembly of the invention to travel from high to low pressure ports. The high and low pressure ports, respectively, are each preferably color coded, as for example, red for high pressure and blue for low pressure, and sealing caps are provided for closing off the ports when a port is not connected to a line or hose that connects to a check/bleed connector.
