About the Airtac PHW F Thread Swivel Tee Fitting PHW603
The PHW603 is an AirTAC PHW double universal male elbow: a one-touch fitting with two swivel joints in one body, terminating in a male 3/8in PT thread. It accepts Dia 6 mm soft nylon or polyurethane tube. Push the tube in and the stainless spring gasket plus chuck grip it; press the POM release ring and it lets go.
Because both ends swivel independently, the part can absorb misalignment on two axes at once, not just one like a single universal elbow. This is the resin and brass one-touch profile: 0 to 1.0 MPa working pressure, proof pressure 1.5 MPa, vacuum down to -750 mmHg, and -20 to +70 C. The elbow body is PBT with a brass stud, the guide is aluminium alloy, and the 3/8in thread arrives pre-coated with sealant so no tape or paste is needed on the port.

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 Is Used
Robotic gripper airline
On a pick-and-place robot arm, the wrist rotates through many degrees. The double swivel lets the fixed port side and the tube side each find their own angle, so the 6 mm line to the gripper cylinder never fights the motion or kinks at the elbow.
Misaligned port on a carton sealer
Packaging machinery often has cylinder ports cast at odd angles and tube runs coming in from two directions. A PHW603 at the 3/8in port swivels on both joints, squaring up the connection where a rigid elbow would sit cross-threaded or side-loaded.
Swing arm on a printing press
Ink-roller swing arms and tension rollers on press ancillaries move through an arc and need a short 6 mm feed that can articulate. The two-joint PHW shape tracks that arc without forcing the tube, keeping the vacuum-rated seal down to -750 mmHg intact.
Is the Airtac PHW F Thread Swivel Tee Fitting PHW603 the Right Part?
On the 3/8in thread, PHW starts at Dia 6 - this is the smallest tube size offered, so there is no smaller PHW603-style sibling below it. The next step up is PHW803, same 3/8in thread with a Dia 8 bore, and the ladder continues through Dia 10 and Dia 12. If your port is 1/4in, a Dia 6 PHW602 exists instead, giving you the same double-swivel shape on a smaller thread. Note the PHW series has no M5 option at all.
Whatever you choose, the tube OD must match the code exactly: a Dia 6 fitting will not seal on 1/4in (6.35 mm) tube or on 8 mm tube. Flow capacity follows the 6 mm bore, so keep it for cylinders and lines whose air demand is modest rather than stepping it down from a larger supply run.
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 FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), proof pressure 1.5 MPa, usable vacuum down to -750 mmHg (10 Torr), operating temperature -20 to +70 C. The fitting takes Dia 6 mm soft nylon or polyurethane tube and has a 3/8in PT male thread. It belongs to AirTAC's resin and brass one-touch line, with a PBT elbow body, brass stud, POM chuck and release ring, aluminium-alloy guide and NBR O-ring.
No. AirTAC ships the threaded stud with sealant already applied, so it seals straight into a 3/8in PT port. Just confirm the port itself is PT, since this catalogue does not offer the PHW in G or NPT threads, and keep any thread locker off the sealant coating. Hand-tighten, then snug up; the double swivel means alignment comes from the joints, not from over-torque on the thread.
