The AirTAC Airtac PHF Tandem Toggle Joint PHF802-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 PHF802-S is AirTAC's PHF universal female elbow in the stainless-stud variant, taking Dia 8 mm soft nylon or polyurethane tube into a 1/4in PT female thread. Push the tube home and the internal chuck grips it under spring load; press the release ring to free it. Because it is a universal elbow, the female thread swivels relative to the body, so you can tighten the port first and then time the elbow to point exactly where the tube needs to run.
This is the resin and brass one-touch profile: 0-1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C. The -S suffix fits a SUS304 stud for corrosion-prone environments, but the elbow body itself remains PBT - only the stud is stainless. The 1/4in thread arrives with sealant already applied, so no extra tape or paste is needed before assembly.

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.

Palletiser valve manifolds often present a male-threaded exhaust port facing the wrong way. The swivelling female thread lets you tighten the PHF802-S and then aim the elbow so the exhaust tube drops vertically away from the port instead of fouling the frame.
Actuator supply lines above a bottling line's rinse section see constant splash and condensation. The SUS304 stud on this variant stands up to that environment where a plain brass stud would gradually dull and corrode.
Indexing tables usually have a male port part-hidden behind the table casting. A rigid elbow often cannot be oriented once the port is torqued; the PHF802-S is timed after tightening, so the Dia 8 tube exits cleanly toward the guard's cable channel.
On the 1/4in rung of the PHF ladder, Dia 8 sits between two real neighbours: PHF602-S on Dia 6 for lighter instrument lines and small actuator feeds, and PHF1002-S on Dia 10 when the branch feeds a larger cylinder and you want less pressure drop through the bore. The trade either way is tube capacity versus rigidity - smaller tube routes easier, larger tube carries more air.
Tube OD must match exactly: a Dia 8 chuck will not seal on 5/16in or 1/4in tube, so check the old tubing with a calliper before ordering. Choose PHF over a plain PL male elbow when the port you are fitting is already male-threaded and you need the freedom to rotate the outlet after installation.
Quick checklist
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. It accepts Dia 8 mm soft nylon or polyurethane tube in a 1/4in PT female thread, with a SUS304 stud and PBT body in the -S variant.
No on both counts. The chuck is cut for exactly Dia 8 mm tube - a Dia 6 or Dia 10 tube will not seal, so step to PHF602-S or PHF1002-S instead. The -S suffix adds a SUS304 stud only; the pressure, vacuum and temperature figures are identical to the standard PHF802, and the dimensions are unchanged.
