About the Airtac PHF Tandem Toggle Joint PHF4M5D
The PHF4M5D is an AirTAC PHF universal female elbow, the swivelling angled fitting that joins Dia 4 mm soft nylon or polyurethane tubing to a female M5x0.8 port. The female thread accepts a male stud or a screw machined into the port itself, which is why this shape is the usual answer on small manifolds and compact pneumatic components where the port is drilled rather than fitted.
This is the resin and brass one-touch profile: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. Push the tube home and the POM chuck grips it; press the release ring and it frees. Being an M5 part, the thread is sealed by a gasket seat rather than tape or compound, so the small-port torque stays low. The D suffix gives the whole body a black finish instead of the standard grey.

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 PHF4M5D Is Used
Miniature valve manifold ports
M5 ports are drilled directly into compact valve manifolds and pneumatic sub-plates on semiconductor handling and pick-and-place units. The female thread of the PHF4M5D screws down onto the stud or tapped port, and the swivel elbow lets the 4 mm tube route downward instead of straight out of the manifold face.
Analytical and lab sample lines
Small-bore air and purge lines on laboratory instruments and analyser enclosures often use 4 mm tubing to save space. The black body reads cleanly inside instrument casings, and the 0.9 MPa-class grip on soft polyurethane tube suits low-flow carrier air rather than high-delivery actuation.
Compact gripper and jig circuits
Festooned jigs and small pneumatic grippers on electronics assembly lines run 4 mm tube to keep weight and bend radius down. A fixed straight fitting fights the twist in the last 100 mm of a gripper cable path; the PHF universal elbow absorbs that final misalignment without kinking the tube.
Is the Airtac PHF Tandem Toggle Joint PHF4M5D the Right Part?
On the M5 ladder for the PHF series only two tube sizes exist: Dia 4 and Dia 6. Dia 4 is the smallest, so the only neighbour is PHF6M5 above it, which opens the bore for slightly higher delivery on the same tiny port. If your port is 1/8" instead of M5, the PHF401 takes the same 4 mm tube - read your port before ordering, because M5 and 1/8" look nothing alike but get confused constantly on miniature equipment. Note also that PHF in M5 is never offered on the bulkhead or cross shapes; the female elbow is the angled M5 option.
Tube OD must match exactly: this fitting holds Dia 4 mm tube only, and a 1/4 in (6.35 mm) imperial tube will neither seal nor grip 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 PHF Tandem Toggle Joint PHF4M5D FAQ
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. It joins Dia 4 mm soft nylon or polyurethane tube to a female M5x0.8 thread, sealed by a gasket, with a black body (D suffix) and PT-family heritage in the AirTAC resin one-touch line.
M5x0.8 is the standard miniature port on compact valves, sensors and small cylinders, and it is sealed with a gasket rather than thread sealant - so no compound can migrate into a narrow 4 mm bore. If your port is tapped 1/8" PT instead, order PHF401, which carries the same Dia 4 mm tube on the larger thread.
