About the Airtac PH-1 Hex Head Toggle Joint PH401D
The AirTAC PH401D is a universal male elbow from the resin one-touch family: a swivelling 1/8 in PT male stud on one side and a Dia 4 mm push-in socket on the other. Push the 4 mm tube home and the internal chuck grips it under system pressure; press the POM release ring and the tube slides out again. The body on the D suffix is moulded in black, which on the PH series means the whole fitting, not just the button.
This is the resin spec profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg, proof pressure 1.5 MPa, and a -20 to +70 C temperature window. The elbow pivots on the stud, so after the 1/8 in thread is sealed into the port (sealant is pre-applied from the factory) the outlet can be swung to point in the direction the tube actually runs.

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 PH-1 Hex Head Toggle Joint PH401D Is Used
SCARA robot wrist pick-and-place
Vacuum and gripper lines at a robot wrist change direction constantly as the arm rotates; the PH401D lets the Dia 4 tube leave the 1/8 port in whatever direction the dress-pack runs, instead of being forced into a kinked 90 degree bend.
Tabletop labelling machine head
On a compact labelling head the air cylinder sits under a guard with the port pointing up but the 4 mm tube routed sideways. The swivelling elbow turns the outlet after installation, so the tube exits flat along the machine plate.
Bench-top test rig plumbing
Prototype rigs built from 4 mm soft nylon or PU tube around 1/8 PT instrument ports benefit from a fitting that can be re-oriented during teardowns; the release ring frees the tube without cutting it back.
Is the Airtac PH-1 Hex Head Toggle Joint PH401D the Right Part?
Dia 4 mm is the smallest tube the 1/8 in PH universal elbow accepts, so there is no step down on this thread. Stepping up goes to the PH601 with Dia 6 tubing, then PH801 at Dia 8; each step up in bore gives the line more capacity on a fixed supply, which matters on short feeds to small single-acting actuators. If your port is M5 instead of 1/8 PT, the equivalent part is the PH4M5, and note that M5 sizes seal with a gasket rather than thread sealant.
Check two things before ordering. First, the port: 1/8 in PT here, and every part in this catalogue is PT - there is no G or NPT variant. Second, the tube: OD must match exactly, so a Dia 4 PH socket will not hold 1/4 in (6.35 mm) imperial tube. Where you need a fixed 90 degree turn instead of a swivel, the PL male elbow is the non-pivoting alternative.
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 PH-1 Hex Head Toggle Joint PH401D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. It joins Dia 4 mm soft nylon or polyurethane tube to a 1/8 in PT male thread, with a black body (D suffix). This is the resin one-touch profile; the metal BP family is rated 0.9 MPa but tolerates up to 150 C, which this part does not.
On the PH series the D suffix colours the whole body black; on the PC and POC straight connectors it only changes the release button. Functionally the fittings are identical - same 0-1.0 MPa resin rating, same chuck and POM release ring - so the choice is purely about matching your machine's styling or visibility needs on the panel.
