About the Airtac PHF Tandem Toggle Joint PHF4M5
The PHF4M5 is an AirTAC PHF universal female elbow, the swiveling female-threaded elbow in the resin one-touch range. It joins Dia 4 mm soft nylon or polyurethane tubing to a female M5x0.8 port, and the universal joint lets the threaded half rotate and the elbow take any angle, so the outlet can be aimed exactly where the tube needs to run.
Push the tube into the chuck and the stainless spring gasket grips it for a seal under 0-1.0 MPa (0-10 kgf/cm2) working pressure and down to -750 mmHg (10 Torr) vacuum; press the POM release ring to free it. Proof pressure is 1.5 MPa and the service temperature window is -20 to +70 C. The threaded section is PBT, and because this is the M5 size AirTAC supplies it with a sealing gasket rather than pre-applied thread sealant - a detail worth knowing before you reach for tape.

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 PHF4M5 Is Used
M5 pilot ports on solenoid valve manifolds
Many compact 5/2 and 3/2 valves carry an M5x0.8 pilot or exhaust port. The PHF4M5 threads straight on and swivels, so Dia 4 pilot tubing can be routed around the manifold without fighting the elbow orientation.
Small pick-and-place gripper feeds
Miniature parallel grippers on electronics assembly heads often accept M5 ports. The Dia 4 bore matches the short air demand of a gripper, and the universal elbow lets the supply tube exit vertically clear of the tool changer.
Bench-top lab and ink-marking equipment
Laboratory pneumatic fixtures and small ink-jet or dot-peen marking heads use M5 ports in tight housings. The female thread lets you seal the fitting onto the stud without rotating the tube line inside the enclosure.
Is the Airtac PHF Tandem Toggle Joint PHF4M5 the Right Part?
Dia 4 is the smallest tube bore the PHF M5 thread is offered in; the only other is Dia 6 (PHF6M5), so stepping up gives you 50% more bore for short runs to a small cylinder or gripper. On the thread side, M5 is the floor of the ladder - the next port up is 1/8 in PT (PHF401), which opens the Dia 4, 6 and 8 tube options. Tube OD must match exactly: a Dia 4 chuck will not seal on 5/32 in or 3 mm tube, so check the old tube with a caliper before ordering.
Choose this universal female elbow over the fixed PL male elbow when the port itself must not be twisted during installation - you torque the female thread onto the stud with a spanner while the elbow body and tube stay still. If you do not need to re-aim the outlet, a PL saves money; if you need a male thread instead of female, that is the PH, not the PHF.
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 PHF4M5 FAQ
Tube size Dia 4 mm, female thread M5x0.8 (PT standard family, sealing gasket fitted). Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C, for soft nylon or polyurethane tubing. Body PBT with POM release button and chuck, aluminium-alloy guide, stainless spring gasket and NBR O-ring.
Unlike the larger PT sizes, which arrive with sealant pre-applied to a male thread, the M5 PHF4M5 seals on its supplied gasket. Fit the gasket, thread the fitting on by hand, then tighten the hex with a spanner while holding the elbow body so no twist is transferred to the tubing or the release ring. Do not add PTFE tape to a gasket-sealed M5 port.
