About the Airtac PHW F Thread Swivel Tee Fitting PHW803D-S
The PHW803D-S is an AirTAC double universal male elbow from the resin one-touch range, joining Dia 8 mm soft nylon or polyurethane tubing to a 3/8 in PT male thread. What sets PHW apart from a fixed PL elbow is the double swivel: the male thread and the tube socket each pivot independently, so the fitting can articulate in two planes. That means a bent or twisted air line can be squared up after installation instead of fighting the tube into alignment.
Push the tube home and the internal chuck grips it; press the release ring and it slides free. This grey-standard catalogue part ordered with the D suffix and -S option carries a black body and a SUS304 stainless stud, while the socket body itself stays PBT. Ratings are the standard resin profile: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, -20 to +70 C. The stud is where the -S earns its keep on this SKU: it resists corrosion on the thread that is most exposed to the environment.

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 PHW803D-S Is Used
Rotary index table actuators
On a packaging machine's rotating index dial, the air port turns with the table. The double universal joint lets the fitting follow the rotation without torquing the Dia 8 tube against the chuck.
Robot wrist gripper circuits
A pick-and-place robot wrist reorients continuously. PHW803D-S gives the 3/8 in PT supply connection a pivot at each joint, absorbing wrist motion that would otherwise fatigue a fixed elbow.
Marine and wash-area valve manifolds
Where the 3/8 in PT port sits near salt spray or wash-down splash, the SUS304 stud holds up on the threaded interface while the PBT swivel body keeps the assembly light and the routing flexible.
Is the Airtac PHW F Thread Swivel Tee Fitting PHW803D-S the Right Part?
At 3/8 in PT this size ladder runs Dia 6, 8, 10 and 12, so PHW603 steps down one bore and PHW1003 steps up. Dropping to Dia 6 suits lighter actuator circuits; stepping to Dia 10 reduces restriction on longer runs. On thread, Dia 8 tube is also offered at 1/4 in (PHW802) and 1/2 in (PHW804), so you can keep the bore and change only the port. Note there is no M5 option anywhere in the PHW range. Whichever you pick, the socket accepts Dia 8 mm tube only - it will not seal 5/16 in or 10 mm hose, so measure the tube, not the label.
Choose PHW over PL when the port and the tube path are not in the same plane - for example where the fitting must angle up and then sideways around a machine frame. If you need a straight connection, PC is the simpler part.
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 PHW803D-S FAQ
It joins Dia 8 mm tubing to a 3/8 in PT male thread with a double universal swivel action. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg, proof pressure 1.5 MPa, and operating temperature -20 to +70 C. It runs on soft nylon or polyurethane tube. This is the stainless -S version: SUS304 stud, PBT swivel body, black finish.
Only the stud material. On PHW parts the -S option makes the male thread stud SUS304 stainless steel for corrosion resistance; the swivel body remains PBT and every pressure, vacuum and temperature rating stays identical to the standard PHW803D. If your spec calls for an all-stainless body, that applies to the PC and POC straight connectors, not this elbow.
