About the Airtac PHF Tandem Toggle Joint PHF4M5-S
The PHF4M5-S is an AirTAC PHF universal female elbow, the swivelling one-touch fitting that joins Dia 4 mm soft nylon or polyurethane tubing to an M5x0.8 female port. Push the tube home and the stainless spring gasket and chuck grip it; press the release ring to free it. The female thread can be screwed onto the mating stud and then the elbow body rotated to point the tube exactly where it needs to run, which is what separates PHF from a fixed PL elbow.
This is the resin/brass spec profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum down to -750 mmHg (10 Torr), and a temperature window of -20 to +70 C. The -S suffix makes the threaded STUD SUS304 stainless while the elbow body remains PBT, so the stainless sits exactly where the spanner contacts the part. Note that M5 sizes seal with a captive gasket rather than the pre-applied thread sealant used on larger PT threads.

POM release button and chuck, aluminium-alloy guide, stainless spring gasket, NBR O-ring; body brass or PBT depending on the part. Stainless (-S): SUS304 in place of brass - a solid SUS304 body on the PC and POC straight connectors, and a PBT body with a SUS304 stud on the elbow, tee and branch shapes. Working pressure, proof pressure and temperature are unchanged from the standard version. AirTAC publishes flow as a characteristic curve rather than a single figure, so no L/min value is listed.

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 PHF4M5-S Is Used
Lab gas analyser sampling line
Routes a Dia 4 soft nylon sample line off the M5 port of a small solenoid manifold inside a benchtop analyser, where the swivel body lets the tube exit around a crowded wiring loom.
Pick-and-place nozzle block
Connects Dia 4 polyurethane tubing to the M5 purge or vacuum port on an SMT placement head, with the swivel keeping the line clear of the Z-axis travel at working pressures up to 1.0 MPa.
Indexing table fixture hold-down
Feeds a small vacuum clamp on a rotary indexing fixture at -750 mmHg, with the SUS304 stud standing up to repeated spanner work and coolant splash at the fixture edge.
Is the Airtac PHF Tandem Toggle Joint PHF4M5-S the Right Part?
Dia 4 is the smallest tube size the PHF M5 ladder offers, so there is no smaller neighbour - only PHF6M5-S above it, which steps the bore up to feed lines with noticeably higher demand. If your port is larger than M5, the same Dia 4 tube is also available on PHF401 with a 1/8" thread. Always match tube OD exactly: a Dia 4 fitting will not seal on 5/32 inch tube, which is a different inch-based series entirely.
Choose the universal shape when the fitting must thread on first and aim afterwards - a fixed elbow has to be installed at exactly the right rotation, which is often impossible on pre-tapped valve or manifold ports.
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 PHF4M5-S FAQ
Working pressure is 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, and vacuum rating -750 mmHg (10 Torr). It operates from -20 to +70 C with soft nylon or polyurethane tubing. This specific SKU joins Dia 4 mm tube to an M5x0.8 female thread, and the threaded stud is SUS304 stainless.
No. On PHF-family parts the -S upgrade applies to the threaded stud, which becomes SUS304; the elbow body stays PBT with a POM release button and chuck. Pressure, vacuum and temperature ratings and all dimensions are identical to the standard PHF4M5, so you gain corrosion resistance at the wrench interface without re-checking any sizing.
