About the Airtac PHF Tandem Toggle Joint PHF601
The PHF601 is an AirTAC PHF universal female elbow, a one-touch fitting that joins Dia 6 mm soft nylon or polyurethane tubing to a 1/8 in PT female thread. Unlike a fixed PL elbow, the universal joint lets the threaded end swivel, so the elbow can be oriented to match the tube run rather than forcing the tube around a hard corner. Push the tube into the collet and the stainless spring gasket and POM chuck grip it instantly; press the release ring and it slides back out.
This is a resin-series part: POM button and chuck, aluminium-alloy guide, brass/PBT threaded parts with an NBR O-ring. It is rated 0-1.0 MPa working pressure, 1.5 MPa proof, -20 to +70 C, and it also holds -750 mmHg vacuum, so the same fitting can serve a vacuum pick line and a pressure line. The 1/8 in thread arrives with sealant already applied.

Fitting & Sealing Notes
- check Cut the tube square and clean before pushing it home, or the seal will leak.
- check Push until it stops, then pull back to check the chuck has gripped.
- check To release, press the collet ring fully in and pull the tube out.
- check Threaded parts arrive with sealant on the thread; M5 sizes use a sealing gasket.
- check Match the tube OD exactly - a 6 mm fitting will not hold 1/4" tube.
Where the Airtac PHF Tandem Toggle Joint PHF601 Is Used
Solenoid manifold on a packaging machine
Packaging machines often mount solenoid islands with male 1/8 in ports facing awkward directions. The female thread on the PHF601 screws straight onto the existing stud and the swivelling elbow turns to face wherever the Dia 6 line needs to run, with no extra street elbow in between.
Pick-and-place gripper lines
On a robotic pick-and-place end effector, small pneumatic grippers sit close to the wrist joint where straight fittings foul the moving parts. The Dia 6 bore matches the short gripper supply lines, and the universal elbow angles the tube away from the mechanism without kinking it each cycle.
Bench-top vacuum pick station
Lab and small-batch assembly benches use venturi vacuum generators fed by 6 mm tube. The PHF601 is rated down to -750 mmHg as well as 1.0 MPa, so one fitting handles both the vacuum side and the compressed-air side of the same station, swivelled to suit the generator ports.
Is the Airtac PHF Tandem Toggle Joint PHF601 the Right Part?
On the PHF ladder at 1/8 in, Dia 6 sits between the smallest option, PHF401 (Dia 4), and PHF801 (Dia 8). Stepping to Dia 4 buys routing freedom in very tight builds; stepping to Dia 8 lowers restriction on runs feeding larger cylinders or longer tube lengths. If you need more bore again, note that PHF only reaches Dia 6 on 1/8 in - the next step up in flow means moving the thread to 1/4 in, where PHF runs from Dia 6 to Dia 10.
Match the thread to the port, not the other way round: the female thread lets you screw the fitting onto an existing male stud, which is why it is the usual choice on valve and cylinder ports that already carry a male boss. Tube OD must match exactly - a Dia 6 body will not seal on 1/4 in tube no matter how hard you push it.
Quick checklist
- ✓ Tube outside diameter matches exactly
- ✓ Thread size and standard match the port
- ✓ Working pressure within 0 - 1.0 MPa (0 - 10 kgf/cm2)
- ✓ Temperature within -20 to +70 °C
Airtac PHF Tandem Toggle Joint PHF601 FAQ
The PHF601 accepts Dia 6 mm soft nylon or polyurethane tube and has a 1/8 in PT female thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), proof pressure is 1.5 MPa, it holds -750 mmHg (10 Torr) vacuum, and the temperature range is -20 to +70 C. The body is PBT with a POM chuck and release button, aluminium-alloy guide, stainless spring gasket and NBR O-ring.
No. That is the point of the PHF shape: the threaded end is a universal joint, so after screwing the fitting onto the male port you can pivot the tube-side body to the angle the line actually needs. Keep in mind the thread is PT only in this catalogue with sealant pre-applied, so do not plan on ordering a G or NPT variant - the swivel covers the alignment instead.
