About the Airtac PHW F Thread Swivel Tee Fitting PHW803-S
The AirTAC PHW803-S is a double universal male elbow: a Dia 8 mm one-touch tube socket on one end, a 3/8in PT male thread on the other, and two swivel joints in between so the tube can leave at almost any angle. Push the polyurethane or soft nylon tube in and the stainless spring gasket plus chuck grip it; press the release ring and it frees again. The PHW shape is the choice when a single fixed elbow cannot face the direction the hose run needs.
This -S variant carries a SUS304 stainless stud on a PBT body - the stainless sits in the thread, where moisture and wash-down splash land first. Ratings are identical to the standard part: 0-1.0 MPa working pressure, 1.5 MPa proof pressure, -20 to +70 C, and -750 mmHg vacuum. Threaded sections arrive with sealant applied, so the 3/8in port seals on installation without extra tape.

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 PHW803-S Is Used
Robot wrist gripper line
On a 4-axis pick-and-place arm, the Dia 8 mm supply to the gripper cylinder has to bend twice around the wrist joint; the double swivel absorbs both direction changes without kinking the polyurethane tube, and the SUS304 stud shrugs off coolant mist near the tool point.
Rotary filling head
A rotary bottle-filling carousel feeds vacuum and air through the centre column; at each station the 3/8in threaded port and the incoming Dia 8 hose rarely align, so the two universal joints let the line drop in at the angle the turret actually presents.
Wash-down conveyor diverters
In a food-plant diverter-gate manifold, splash and daily hose-down attack the exposed threaded stud first; the SUS304 stud on this elbow resists that corrosion while the 3/8in PT thread with factory sealant drops straight into the stainless manifold port.
Is the Airtac PHW F Thread Swivel Tee Fitting PHW803-S the Right Part?
For the 3/8in thread the PHW ladder offers Dia 6, 8, 10 and 12 tubes, so step down to PHW603 for lighter pick-and-place lines or up to PHW1003 when the circuit feeds a larger actuator; the swivel geometry stays the same. If the port is 1/4in instead, PHW802 covers the same Dia 8 tube at the smaller thread. Note that the PHW series has no M5 entry at all - small-bore work has to move to the PL or PC families.
Match the stud to a 3/8in PT port and keep the tube OD exact: the chuck is machined for Dia 8 mm and will not seal 5/16in or 10 mm tube. When you need the tube to exit twice, a PH single universal elbow or a PED run tee may suit better; pick the PHW when two angle changes in series are unavoidable.
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 PHW803-S FAQ
It joins Dia 8 mm soft nylon or polyurethane tube to a 3/8in PT male thread with a SUS304 stud on a PBT body. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, negative pressure down to -750 mmHg (10 Torr), and operating temperature -20 to +70 C. The stainless option does not change any of these figures - only the stud material.
Yes. The double universal joints let you set both tube angles independently, so you can push the Dia 8 tube home first, thread the stud into the 3/8in port, then rotate the body to point the hose where the routing needs it. Keep the release ring accessible, though - if it ends up buried against a machine wall you will need to remove the whole fitting to free the tube.
