About the Airtac PHW F Thread Swivel Tee Fitting PHW603-S
The PHW603-S is an AirTAC PHW double universal male elbow: a one-touch fitting that joins Dia 6 mm soft nylon or polyurethane tubing to a 3/8in PT male thread, with two swivelling joints so the tube can leave in any plane. Push the 6 mm tube into the chuck until it bottoms, and the stainless spring gasket and POM chuck grip it for a sealed connection; press the release ring and the tube frees out again.
This is the resin/brass one-touch profile: 0 to 1.0 MPa working pressure, -750 mmHg vacuum capability, 1.5 MPa proof pressure and a -20 to +70 C service window, with the thread arriving pre-coated with sealant. The -S suffix adds a SUS304 stainless stud while the elbow body remains engineering PBT, so it is not a solid stainless part - the stainless sits where the fitting meets your port, giving corrosion resistance at the threaded interface without re-rating any pressure or temperature figure.

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 PHW603-S Is Used
Packaging machine valve manifold
On a horizontal flow-wrapper, the 3/8in PT ports of the directional control valve sit at an awkward angle inside the guard; the double universal elbow lets a 6 mm PU drop line approach from whatever direction the cable tray allows.
Pick-and-place gripper feed
A two-jaw pneumatic gripper on a Cartesian gantry swings through multiple axes; the twin swivel joints keep the 6 mm feed tube from twisting or fretting against the bracket as the wrist rotates.
Wash-down conveyor actuator
On a food-line conveyor where the port hardware sees regular caustic hosing, the SUS304 stud resists corrosion at the threaded connection while the 6 mm line runs out to a small kick cylinder.
Is the Airtac PHW F Thread Swivel Tee Fitting PHW603-S the Right Part?
Step down and the PHW ladder offers Dia 4, but only paired with a 1/8in thread (PHW401) - there is no Dia 4 body on the 3/8in thread. Step up to Dia 8 (PHW803) when the line feeds a larger bore cylinder or wants lower resistance at the same flow demand, since capacity tracks the tube bore rather than the fitting shape. Holding the 6 mm tube and changing thread, PHW602 (1/4in) and PHW604 (1/2in) are the alternatives on this prefix, and note the PHW series starts at 1/8in - no M5 version exists anywhere in this family. The tube OD must match exactly: the 6 mm chuck will not seal on 1/4in (6.35 mm) imperial tube.
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 PHW603-S FAQ
It is a double universal male elbow for Dia 6 mm tubing with a 3/8in PT male thread. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum capability is -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the working temperature range is -20 to +70 C with soft nylon or polyurethane tube. The -S variant carries a SUS304 stainless stud; the PBT body, POM chuck and NBR seal follow the standard resin-line construction, and none of the ratings change with the stainless option.
No. The chuck and gasket in the PHW603-S are sized for 6 mm OD metric tube only, and 1/4in tube measures about 6.35 mm - close enough to seem like it fits, but it will not seal and can blow out under pressure. Match the tube OD exactly, or move to a fitting in the correct size. Within the PHW stainless range the neighbouring options are PHW401 for Dia 4 (1/8in thread only) and PHW803 for Dia 8 on the same 3/8in thread.
