The NORGREN C00600600 is a push-to-connect union tee tube fitting machined from brass and rated to 150 psi maximum working pressure. It joins three tube runs at a single junction without tools, using a push-in collet mechanism that grips and seals around the tube outside diameter. The fitting accepts 6 mm OD tubing and uses a nitrile O-ring for the primary seal, making it suitable for pneumatic and fluid-handling lines operating between 0 degrees F and 175 degrees F. Plumbers, HVAC technicians, and pneumatic system installers use this style of fitting where quick, reliable tube connections are needed in tight spaces.
This union tee is suited for residential and light commercial pneumatic circuits, instrument air lines, and fluid distribution systems where 6 mm OD tubing is run in a branch configuration. The push-to-connect design makes it appropriate for new installations and service repairs alike, particularly in applications where soldering or compression tooling is not practical. It is commonly used in control air tubing, small-bore fluid transfer, and similar low-to-medium pressure plumbing or pneumatic assemblies.
Designed as an OEM-style push-to-connect union tee replacement for pneumatic and fluid-handling systems using 6 mm outside diameter tubing at working pressures up to 150 psi.
Installation is performed by licensed plumbers or qualified pneumatic technicians. Depressurize and isolate the line completely before removing any existing fitting or inserting this tee. Confirm tube ends are cut square and deburred before insertion — damaged tube ends prevent proper collet engagement and can cause leaks. Verify the system operating pressure and temperature do not exceed the rated limits of this fitting before returning the circuit to service.
