About the Airtac PHW F Thread Swivel Tee Fitting PHW801-S
The PHW801-S is an AirTAC double universal male elbow from the resin one-touch range. It connects Dia 8 mm soft nylon or polyurethane tubing to a 1/8in PT male port, and unlike a fixed PL elbow it swivels at both the threaded end and the tube end, so the angle can be set after the fitting is installed and the tube can leave at whatever direction the route needs. Push the tube in and the internal chuck grips it; press the release ring and it frees.
The -S suffix means the male stud is SUS304 stainless steel while the body stays glass-reinforced PBT and the release button stays POM, with a stainless spring gasket and NBR O-ring inside. It is not a solid stainless part and it is not rated differently: the resin spec applies, working pressure 0-1.0 MPa, proof pressure 1.5 MPa, temperature -20 to +70 C, vacuum down to -750 mmHg. The stainless stud earns its place where the port thread sees moisture or washdown, such as wet or humid plant areas.

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 PHW F Thread Swivel Tee Fitting PHW801-S Is Used
Robot gripper air lines
On an end-of-arm tooling the port orientation changes with the gripper mounting, so a swivelling elbow that can be re-aimed after installation avoids re-bending tube runs every time the wrist is re-tooled.
Tray-sealing machine vacuum assist
A packaging tray sealer with small pneumatic assist cylinders packed between the frame rails benefits from the double swivel: the 1/8in PT stud threads into the valve manifold and the Dia 8 tube exits at the angle the tight guard space allows.
Fume-extraction cabinet actuation
On a laboratory extraction or dosing cabinet where the port threads are exposed to condensation, the SUS304 stud resists corrosion at the connection while the PBT one-touch body keeps the Dia 8 nylon line easy to service.
Is the Airtac PHW F Thread Swivel Tee Fitting PHW801-S the Right Part?
This sits at the top of the PHW ladder for a 1/8in thread: Dia 6 (PHW601) is the size below, and Dia 8 is the largest tube this thread is offered with, so there is no step up on 1/8in. If your circuit grows, the thread ladder continues: PHW802 carries the same Dia 8 tube onto a 1/4in PT port. Remember the interface rule - each PHW thread only accepts specific tube sizes, so check the pair before ordering.
Choose this double universal shape over a fixed PL elbow when the direction of the tube run is not known at design time, or when you need to thread the fitting into the port first and swing the tube end to line up afterwards. Tube OD must match exactly: a Dia 8 chuck will not seal on 10 mm or 5/16in tube, no matter how hard it is pushed in.
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 PHW F Thread Swivel Tee Fitting PHW801-S FAQ
It is a double universal male elbow joining Dia 8 mm tubing to a 1/8in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and working temperature -20 to +70 C. The body and release button are PBT/POM and the male stud is SUS304 stainless steel.
No to both. On the PHW family the -S suffix upgrades the male stud to SUS304 while the body remains PBT, and copper-free construction is only claimed on the -S versions of the PC and POC straight connectors, where the body itself is stainless 304. The pressure, vacuum and temperature ratings of the PHW801-S are identical to the standard PHW801.
