The AirTAC Airtac PHF Tandem Toggle Joint PHF602D-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.
PHF602D-S is the AirTAC PHF universal female elbow from the one-touch resin family. It joins Dia 6 mm soft nylon or polyurethane tube to a 1/4 in PT female thread, with the tube outlet set at 90 degrees to the port. Push the tube home and the internal chuck grips it; press the POM release ring and the tube frees off again. No ferrules, no clamps, no tube preparation.
This is the resin spec profile, not the 0.9 MPa metal line: working pressure 0-1.0 MPa, temperature -20 to +70 C, proof pressure 1.5 MPa, vacuum to -750 mmHg. On this -S variant the stud behind the female thread is SUS304 stainless, so the part that meets the machine port resists corrosion while the elbow body stays PBT. The D in the code makes the body black - on the PHF series that means the whole body, unlike PC and POC where D only changes the release button.

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.

On a compact 5/2 valve feeding a Dia 6 polyurethane line, the female elbow threads straight onto the valve's male stud and turns the tube run 90 degrees to follow the manifold face instead of sticking out into the wiring duct.
The SUS304 stud resists corrosion where splash and fumes near a plating or wash station would quickly dull a plain brass stud, while the Dia 6 nylon line feeds a rinsing nozzle or air knife above the tank.
Where a small bore cylinder sits behind sheet-metal guarding, the female elbow mounts on the port and points the Dia 6 tube along the guard wall, clearing the limit switch and cable route a straight connector would block.
At Dia 6 on a 1/4 in port this is the smallest tube PHF offers in that thread - the 1/4 in row starts at Dia 6, so there is no Dia 4 step down here. Step the tube up to Dia 8 on the same thread and you are at PHF802D-S; keep Dia 6 and drop the port to 1/8 in for PHF601D-S, or raise the port to 3/8 in for PHF603D-S. Match the thread to the port on the valve or manifold rather than to the old part number, and remember every thread in this catalogue is PT.
Tube OD must match exactly. A Dia 6 chuck will not hold 1/4 in (6.35 mm) imperial tube, and no imperial size exists anywhere in this range - if your run is imperial, this is the wrong family.
Quick checklist
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting joins Dia 6 mm tube to a 1/4 in PT female thread. These are the resin one-touch ratings, and the -S stainless-stud version carries exactly the same figures.
On the PHF family, -S fits a SUS304 stainless stud at the thread; the elbow body itself remains PBT, so this is not a solid stainless fitting. Pressures, temperatures and dimensions are identical to the standard PHF602D. Only the PC and POC straight connectors receive a full stainless 304 body - the elbows get the stainless stud.
