About the Airtac PHF Tandem Toggle Joint PHF401D
The PHF401D is an AirTAC PHF universal female elbow, a push-to-connect 90 degree fitting that joins Dia 4 mm soft nylon or polyurethane tubing to a 1/8 inch PT female thread. Because the thread is female and swivels, the elbow can be rotated onto a male stud port and left sitting square to the actuator or valve body, instead of fighting the hose for alignment the way a fixed male elbow does. To connect, push the tube fully home; the stainless spring gasket and chuck inside the collet grip the OD and seal immediately. Pressing the POM release ring frees the tube again. The body is PBT with a brass stud, the guide is aluminium alloy, and the O-ring is NBR.
This is the resin one-touch spec profile: 0 to 1.0 MPa working pressure (0 to 10 kgf/cm2), -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and a -20 to +70 C temperature window. The D suffix on the PHF family changes the body colour to black, not just the release button as it does on PC and POC straight connectors, so the fitting stays visually consistent on machines where black components are specified. Every threaded part arrives with sealant already applied to the thread, so no tape or paste is needed at installation.

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 PHF401D Is Used
PCB pick-and-place heads
Electronics assembly heads running small gripper cylinders on 4 mm polyurethane hose use the swivel female thread to sit flush against a cylinder shoulder, so the hose leaves at a clean angle inside a cramped gantry.
Lab autosampler actuation
On laboratory autosamplers and analytical instruments, the Dia 4 bore matches the thin actuator lines, and the female swivel lets the elbow be clocked square to a male instrument port without twisting the tube.
Cartoner vacuum cup lines
Packaging cartoners cycling vacuum cups on thin soft nylon line exploit the -750 mmHg vacuum rating of the resin profile, with the angled female body freeing the hose from torsion on every stroke.
Is the Airtac PHF Tandem Toggle Joint PHF401D the Right Part?
Dia 4 mm is the smallest tube the PHF ladder offers at a 1/8 inch thread, so there is no smaller sibling on this thread - the only step down in tube size is the M5-threaded PHF4M5, which keeps the same 4 mm bore but drops to an M5x0.8 port with a sealing gasket instead of tapered thread sealant. Stepping up one size gives the PHF601 (Dia 6 tube, same 1/8 inch female thread), which gains bore for slightly higher delivery to the same port. Remember the OD must match exactly: a Dia 4 chuck will not seal or hold 6 mm or 1/4 inch tube, and no adapter changes that.
Choose the PHF shape over the male PL elbow when the port on the machine is a male stud and you want the fitting body to swivel square before the chuck locks the tube angle. If you need to pass the connection through a panel wall, the PMF bulkhead female connector is the right family instead; if two line sizes must meet, the different-diameter tees (PEG, PEW) handle that, not an elbow.
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 PHF401D FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2); negative pressure -750 mmHg (10 Torr); proof pressure 1.5 MPa; working temperature -20 to +70 C. The fitting joins Dia 4 mm soft nylon or polyurethane tube to a 1/8 inch PT female thread. It is a resin one-touch universal female elbow with PBT body, brass stud, POM release ring, aluminium alloy guide, stainless spring gasket and NBR O-ring; the D suffix gives a black body, and the thread is supplied pre-coated with sealant.
No. One-touch chucks are machined for a single tube OD, and this fitting grips only Dia 4 mm; a 6 mm tube will not seat in the collet and will leak or blow out. For 6 mm tube on the same 1/8 inch female thread, order the PHF601. If your port is smaller than 1/8 inch, the PHF4M5 keeps the 4 mm bore on an M5x0.8 thread instead.
