About the Airtac PH-1 Hex Head Toggle Joint PH401
The PH401 is an AirTAC PH universal male elbow - a one-touch fitting that joins Dia 4 mm soft nylon or polyurethane tube to a 1/8 inch PT male thread at a right angle. Push the tube fully home and the internal chuck grips it against the stainless spring gasket; press the release ring and the tube slides straight back out. Unlike a fixed elbow, the universal head swivels, so you can tighten the thread first and then clock the outlet to point exactly where the tubing needs to run.
This is the resin and brass spec profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa and a temperature window of -20 to +70 C. The release button and chuck are POM, the guide is aluminium alloy, the seal is NBR, and the body is PBT on a brass stud with sealant already applied to the thread.

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 PH401 Is Used
Slim gripper plumbing on pick-and-place heads
On a packaging machine's pick-and-place module, a 4 mm polyurethane line must exit a compact gripper at 90 degrees. The PH401 threads in first, then the swivel head is rotated so the tube drops cleanly away from the guide rails instead of fouling them.
Pilot feed to a small valve on a bottling stack
A Dia 4 pilot line feeding a 1/8 inch control valve on a bottling carousel often lands at an awkward angle. Tightening the PH401 into the port and swivelling the outlet gives a clean right-angle take-off without re-clocking the valve body.
Rotating spray-head or turntable actuator feed
On a small rotary indexing table or paint-spray head, a rigid elbow would twist the tubing as the assembly turns through part revolutions. The PH401's universal head lets the 4 mm tube approach on the path of least stress while the thread stays sealed in the port.
Is the Airtac PH-1 Hex Head Toggle Joint PH401 the Right Part?
On the PH ladder with a 1/8 inch thread, Dia 4 is the smallest tube size AirTAC offers - there is no step down. The next sizes up are PH601 (Dia 6) and PH801 (Dia 8); each step raises the bore, so flow capacity through the fitting grows with it. If your port is female rather than male, the PHF401 female universal elbow keeps the same swivelling geometry. Whatever you order, tube OD must match the socket exactly - a Dia 4 fitting will not seal on 1/4 inch (6.35 mm) or 5 mm tube, and vice versa.
Reach for a PH over a standard PL male elbow when the outlet direction has to be set after installation, for example where the thread axis is fixed but the tube run is not.
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 PH401 FAQ
Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it can be pulled to -750 mmHg (10 Torr) vacuum, and proof pressure is 1.5 MPa. The temperature range is -20 to +70 C. The fitting takes Dia 4 mm soft nylon or polyurethane tube on a 1/8 inch PT male thread. These figures are identical to every other resin one-touch part in the AirTAC catalogue.
No. AirTAC applies sealant to the 1/8 inch thread before shipping, so the fitting seals straight into a PT port as supplied. (M5 sizes in the same catalogue use a sealing gasket instead of this coating - that is a different sealing method, not one you can mix in.) The Dia 4 tube is sealed by the internal NBR O-ring and spring gasket, which is why the tube OD must be exactly 4 mm for a leak-free grip.
