The AirTAC Airtac PHF Tandem Toggle Joint PHF601-S is a genuine universal female elbow for push-in tube connection, rated 0 - 1.0 MPa (0 - 10 kgf/cm2) with a 1.5 MPa proof pressure.
The PHF601-S is an AirTAC PHF universal female elbow, a one-touch fitting that joins Dia 6 mm soft nylon or polyurethane tubing to a 1/8 in PT female threaded port. Push the tube home and the chuck grips it; press the POM release button to free it again. Because the outlet swivels on the female stud, the tube run can be aimed at any angle even after the thread has been tightened, which is what separates a PHF from a fixed PL elbow.
The -S suffix fits a SUS304 stainless stud to this elbow. The elbow body itself stays PBT, so this is not a solid stainless part - only the threaded stud that screws into your port is stainless. Ratings are the standard resin-line figures: 0-1.0 MPa working pressure, 1.5 MPa proof pressure, -20 to +70 C, and vacuum to -750 mmHg. The stud arrives with sealant on the thread, so no extra tape is needed on the PT port.

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.

The swivelling female head lets the Dia 6 drop line up with a cylinder port whose approach angle changes from station to station, without kinking or re-bending the tube.
Around rinsing equipment that splashes and mists, the SUS304 stud on the port side holds up better than a plain brass stud, while the PBT elbow body keeps weight off small cylinder ports.
A pre-tapped 1/8 in PT outlet on a pneumatic manifold takes the female thread directly; the elbow turns the Dia 6 tube run 90 degrees away from the manifold face into the cabinet loom.
On the 1/8 in row of the PHF ladder, Dia 6 sits between Dia 4 (PHF401-S) and Dia 8 (PHF801-S). Step down when the line feeds a small actuator or a sensor port where the physical size of the elbow matters more than bore; step up to Dia 8 when the longer run needs more cross-section. Note that PHF stops at Dia 8 on a 1/8 in thread - larger bores only exist on the 3/8 in and 1/2 in rows. If your port is tapped 1/4 in, the PHF602-S carries the same Dia 6 tube on the next thread up.
Tube OD must match exactly: a Dia 6 one-touch chuck will not seal or hold 1/4 in tube, and no amount of insert shimming fixes that. Choose the PHF shape over a straight PC when the tube must leave the port at 90 degrees and over a fixed PL when the exact approach angle of the tube is not known until the machine is assembled.
Quick checklist
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and operating temperature -20 to +70 C. The fitting accepts Dia 6 mm soft nylon or polyurethane tube on a 1/8 in PT female thread with a swivelling universal head.
No. Only the stud becomes SUS304 stainless; the elbow body stays PBT and the release button and chuck stay POM. Every pressure, vacuum and temperature figure is identical to the standard PHF601, and the dimension tables match as well - you are buying corrosion resistance at the port, not a re-rated fitting.
