About the Airtac PHW F Thread Swivel Tee Fitting PHW603D-S
The PHW603D-S is AirTAC's 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 and can pivot on two separate swivel points. You push the tube home until the stainless spring gasket and chuck grip it; the release ring frees it again when you need to re-route. Because the elbow articulates at both the thread end and the tube end, it takes up misalignment that a fixed PL elbow cannot, so the tubing leaves the port at whatever angle the machine actually needs.
This is the resin/brass spec profile: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. The -S suffix fits a SUS304 stud, but the body itself stays PBT - on elbow, tee and universal shapes AirTAC keeps the moulded body and makes only the male stud stainless, so this is a corrosion-resistant thread interface rather than a solid stainless fitting. The D in the code marks the black body version, and the thread arrives with sealant already applied.

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 PHW603D-S Is Used
Robot wrist gripper feed
On a 6-axis robot end effector, the gripper cylinder port rarely points the way the dress pack wants. The double swivel lets a 6 mm line enter at the angle the harness dictates while the 3/8in stud stays square in the port, and the SUS304 stud shrugs off coolant mist near the machining envelope.
Carton squaring cylinder on a case packer
Case-packers swing squaring cylinders through an arc every cycle, and a fixed elbow twists the tube until it fatigues. The PHW603D-S double joint takes up that rotation at the port instead, on a bore matched to 6 mm polyurethane line from the machine's valve manifold.
Plating-line rinse station actuator
In an electroplating rinse section where acid fumes attack brass hardware at the thread, a copper-free SUS304 stud on the 3/8in port keeps the wetted interface corrosion-resistant while the PBT body sits outside the splash zone.
Is the Airtac PHW F Thread Swivel Tee Fitting PHW603D-S the Right Part?
On the 3/8in thread rung of the PHW ladder the sizes run Dia 6, 8, 10 and 12 - Dia 4 is deliberately not offered at 3/8in on this series. So your down-step is a thread change, not a tube change: PHW602 keeps the 6 mm tube on a 1/4in port, while the up-step PHW803 moves you to an 8 mm bore on the same 3/8in thread with a correspondingly larger flow path. Match the thread to the port first, then the tube; the two choices are independent on this series, and PHW is one of the prefixes with no M5 option at all.
Tubing OD must match the fitting exactly - a Dia 6 PHW will not seal 1/4in (6.35 mm) imperial tube, and forcing it in is the classic cause of a slow weep under pressure. If you actually need to join two tube sizes, step across to the PG or PKG reducer shapes instead of trying to stretch this one.
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 PHW603D-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting joins Dia 6 mm soft nylon or polyurethane tube to a 3/8in PT male thread, with a SUS304 stud and PBT body in the black D colourway. It is the resin/brass spec profile, not the 0.9 MPa metal BP line.
No. On the PHW family AirTAC supplies the male stud in SUS304 while the elbow body remains PBT, so you get a corrosion-resistant, copper-free thread interface where it meets the port. The pressure, vacuum, proof-pressure and temperature ratings are identical to the standard PHW603D - the -S never re-rates the part - and the dimension tables match the standard version exactly.
