About the Airtac PHW F Thread Swivel Tee Fitting PHW401D
The PHW401D is an AirTAC PHW double universal male elbow in the resin one-touch range, joining Dia 4 mm soft nylon or polyurethane tube to a 1/8 inch PT male thread. Unlike a single fixed elbow, the PHW pivots at two points, so the thread goes into the port straight and the tube leg can still be aimed wherever the routing needs it. The D suffix makes this the black-bodied version: on the PHW series the colour option changes the whole body, not just the release button as it does on PC.
This is the standard resin spec profile, not the metal line: working pressure 0-1.0 MPa, vacuum down to -750 mmHg, proof pressure 1.5 MPa and a temperature span of -20 to +70 C. The body is PBT with a brass stud, POM release button and chuck, a stainless spring gasket and an NBR seal. Connection is genuinely one-touch: push the tube fully home so the chuck grips it, and press the release ring to free it. The 1/8 thread arrives with sealant already applied, so it seals straight into a PT port.

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 PHW F Thread Swivel Tee Fitting PHW401D Is Used
Pick-and-place gantry piping
On a compact pick-and-place unit the cylinder ports sit at awkward angles inside the extrusion frame. The double swivel lets the 1/8 stud enter the port square while the 4 mm tube leg turns to follow the cable chain path.
Valve manifold exits on packaging machines
Directional valve manifolds on small packaging machines leave little room above the ports. PHW401D turns the 4 mm drop line twice, clearing neighbouring coil stacks without bending the tube against its minimum radius.
Screen printing machine sensor feeds
Vacuum generator and sensor lines on a screen printing press route between dark anodised brackets. The black body of the D version stays visually consistent with the machine hardware while the Dia 4 tube feeds small-diameter actuators.
Is the Airtac PHW F Thread Swivel Tee Fitting PHW401D the Right Part?
Dia 4 is the smallest tube the PHW series is made in - there is no M5 version of this double elbow at all - so there is nothing to step down to. The next size up is the PHW601 for Dia 6 tube, then PHW801 for Dia 8; moving up raises the bore and the flow capacity that comes with it. Note that on this series the 1/8 inch thread is the only one that accepts Dia 4 tube: the 1/4 inch PHW versions start at Dia 6.
Match the thread to the port before anything else: a PT 1/8 male stud seats in a tapped PT port with no extra sealing tape needed. Pick a PHW over a plain PL elbow when the port axis and the tube run cannot meet at a fixed 90 degrees - the two swivel joints absorb alignment error. And the tube wall must match exactly: this fitting grips Dia 4 only, so 5/32 inch or 6 mm tube will not seal in 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 PHW F Thread Swivel Tee Fitting PHW401D FAQ
This is the resin one-touch profile: working pressure 0-1.0 MPa, negative pressure -750 mmHg, proof pressure 1.5 MPa, operating temperature -20 to +70 C. The part is a double universal male elbow for Dia 4 mm soft nylon or polyurethane tube with a 1/8 inch PT male thread, finished in black. Capacity depends on the 4 mm bore, which AirTAC publishes as a characteristic curve rather than a fixed flow figure.
No. On the PHW series the interface table pairs the 1/8 inch thread with Dia 4, 6 and 8 tube, while the 1/4 inch versions begin at Dia 6. For Dia 4 tube at 1/4 inch you would need a different prefix, such as the PC male connector in Dia 4. Keep the tube OD exact: a Dia 4 chuck will not hold 6 mm tube, and forcing a mismatch is the most common cause of leaks at the push-in seal.
