The AirTAC Airtac PHF Tandem Toggle Joint PHF6M5 is a genuine universal female elbow for push-in tube connection, rated 0 - 1.0 MPa (0 - 10 kgf/cm2) with a 1.5 MPa proof pressure.
The PHF6M5 is an AirTAC PHF universal female elbow, a swivelling right-angle one-touch fitting that connects Dia 6 mm soft nylon or polyurethane tube to an M5x0.8 female port. Push the tube fully home and the stainless spring gasket inside the chuck grips it under any angle; press the release ring to free it again. Because the elbow head swivels independently of the thread, you can screw the fitting in and then rotate the tube leg to exactly the direction the run needs - useful where a fixed elbow would twist the tube.
This is a resin-body part with a brass stud, running the standard resin spec: working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature range of -20 to +70 C. One detail worth knowing before you fit it: M5 ports on this catalogue seal with a gasket rather than pre-applied thread sealant, so there is no paste to contaminate a small pilot circuit.

A small Cartesian pick-and-place head in a laboratory dispenser often carries only M5 ports; the swivel head lets the 6 mm pilot tube leave the actuator at whatever angle the gantry cable chain demands.
Board-handling ejectors on SMT benches draw vacuum through tiny ports; this elbow connects the 6 mm vacuum line and, rated to -750 mmHg, holds the negative side without leaking at the gasket.
On a small horizontal bagger, blast-air nozzles mounted close to the frame need an angle change after mounting; screw the PHF6M5 in, swivel the tube leg toward the nozzle, and the 6 mm supply line clears the guard.
On the M5 rung of the PHF ladder only two tube sizes exist: Dia 4 and Dia 6. PHF6M5 is therefore the largest M5 option - the step down is PHF4M5, which suits micro pilot lines where 4 mm tube feeds low-flow actuators. If your port is 1/8 PT instead of M5, the equivalent part is PHF601, and PHF801 opens the tube up to 8 mm on the same thread; the larger bore means measurably less restriction on longer runs to the valve island.
Match the tube exactly: the chuck in a Dia 6 fitting will not hold 1/4 inch (6.35 mm) tube, even though the difference looks trivial on a ruler. And if your assembly needs a male stud into a threaded port rather than a female nut, the PH male elbow is the shape to compare before ordering.
Quick checklist
It is a Dia 6 mm one-touch universal female elbow with an M5x0.8 female thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure goes to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the operating temperature range is -20 to +70 C. The M5 port seals with a gasket, and the thread standard across this catalogue is PT.
No. The internal chuck grips one tube outside diameter only, and here that is exactly 6 mm - a 1/4 inch (6.35 mm) tube will not seat and will blow off under pressure. For a different tube size on an M5 port, the only other choice is PHF4M5; for Dia 6 tube on a larger 1/8 PT port, order PHF601.
