Shop 6564-FG Tee Male JIC - Female JIC Swivel - Female ORB
The Series 6564-FG Tee Adapter, designed with Male JIC x Female JIC Swivel x Female ORB connections, is a versatile hydraulic fitting often referred to as a gauge adapter. It allows users to easily “tee” a pressure gauge or hose whip into a line through the smaller female ORB (O-Ring Boss) port. The JIC (Joint Industry Council) ends feature a 37° flare design that provides a strong, leak-free mechanical seal, while the female JIC swivel connection simplifies installation by allowing rotation without twisting the hose. The ORB connection, which uses an O-ring and straight thread, delivers a reliable hydraulic seal capable of withstanding high pressure. This carbon steel adapter ensures efficient, leak-free connections in diagnostic, monitoring, and control applications across hydraulic and fluid power systems.
