The AirTAC Airtac PHF Tandem Toggle Joint PHF801-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 PHF801-S is an AirTAC PHF universal female elbow, a one-touch push-in fitting that joins Dia 8 mm soft nylon or polyurethane tubing to a 1/8 in PT female thread. The female port screws straight onto an existing male stud on a valve, cylinder or manifold, and the universal joint lets you swing the elbow to the exact angle you need after the thread is tight. Push the tube in and the internal chuck grips it under system pressure; press the release ring and the tube slides straight back out.
As a -S part in the PHF family, this fitting carries a SUS304 stainless steel stud on a PBT body - the body material is unchanged from the standard PHF, only the stud is upgraded. Performance is the standard resin figure set: 0 to 1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C. The 1/8 in thread arrives with sealant applied, and the POM release button, aluminium-alloy guide, stainless spring gasket and NBR O-ring complete the seal stack.

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.

Thread the PHF801-S straight onto the 1/8 in male stud of a compact press cylinder, then swivel the elbow so the Dia 8 supply line clears the press bolster instead of fouling it.
Rated to -750 mmHg vacuum, this elbow suits the Dia 8 supply side of a side-channel ejector on a carton picking head, angled away from the suction cup travel.
The SUS304 stud stands up better than plain brass to occasional splash and rinse-down around an electroplating jig, where theDia 8 air line feeds the lift cylinders.
Dia 8 is the largest tube the PHF ladder offers on a 1/8 in thread - that row stops at 4, 6 and 8. Your neighbour down is PHF601-S on Dia 6 tube, which suits lighter lines and smaller actuators; there is no Dia 10 option on 1/8 in, so if your circuit later grows to Dia 10 or 12 you step to the 1/4 in thread versions such as PHF802 or PHF1002-S. Match the tube OD exactly: this chuck is bored for 8 mm and will not hold 1/4 in (6.35 mm) or 5/16 in tube, even though the numbers look close.
Choose the female elbow shape when the machine already has a male stud and you do not want to cut, re-tap or add a nipple just to change direction. Where the port sits behind a guard or against a wall, the swivel action saves a second fitting that would otherwise be needed purely to angle the tube run.
Quick checklist
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting joins Dia 8 mm soft nylon or polyurethane tube to a 1/8 in PT female thread. In this -S variant the stud is SUS304 stainless steel and the body is PBT; the ratings are identical to the standard PHF801.
No. On the PHF family the -S suffix upgrades the stud to SUS304 stainless steel for corrosion resistance; every pressure, vacuum and temperature figure stays the same as the standard brass-stud version, and the dimensions are unchanged. Note also that the PBT body remains on this family - only the PC and POC straight connectors in the stainless line get a solid stainless body.
