The AirTAC Airtac PHW F Thread Swivel Tee Fitting PHW1003 is a genuine double universal male elbow for push-in tube connection, rated 0 - 1.0 MPa (0 - 10 kgf/cm2) with a 1.5 MPa proof pressure.
The PHW1003 is AirTAC's PHW double universal male elbow: a one-touch fitting that takes Dia 10 mm soft nylon or polyurethane tubing into a 3/8 in PT male thread, with a swivel joint on the tube side AND a swivel joint at the thread, so both halves of the connection can be angled independently. Push the tube home and the stainless spring gasket and chuck grip it; press the release ring and it frees again.
This is the resin and brass one-touch profile: 0-1.0 MPa working pressure, -750 mmHg vacuum capability, 1.5 MPa proof pressure and -20 to +70 C operation. The 3/8 in thread ships with sealant already applied, and unlike some PH-series elbows, the PHW line has no M5 version at all - every part in this series is a tapered pipe thread.

On a rotating indexing dial, a fixed elbow forces the hose to wind up as the table turns. The PHW1003's independently swivelling ends let the feed follow the motion axis instead of fighting it, protecting Dia 10 hose from torsion fatigue.
Carton sealer valve manifolds often sit at an angle to the cylinder ports they supply. A 3/8 in double universal elbow lets the installer square up the hose run to the frame while the thread side takes up the port angle, with no tube bending.
Pneumatic stoppers along a conveyor line get serviced often. The one-touch release on the PHW1003 lets a technician pull the Dia 10 hose free in seconds for cylinder replacement, then push it back without re-making a threaded joint.
On the 3/8 in PT ladder, PHW goes 6, 8, 10, 12. Step down to PHW803 for Dia 8 tube feeding smaller actuators, or up to PHW1203 where a Dia 12 main run needs the same double-swivel geometry at higher flow. At this Dia 10 size you can also change the thread instead: PHW1002 (1/4 in) and PHW1004 (1/2 in) both exist, so match the port you are screwing into before you change the tube.
The double-swivel shape earns its place when a fixed elbow cannot: where the hose must approach from one direction and the port face sits at another. Remember the tube OD must match exactly - a Dia 10 fitting will not seal on 3/8 in (9.5 mm) or 12 mm tube.
Quick checklist
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. It joins Dia 10 mm soft nylon or polyurethane tube to a 3/8 in PT male thread and is a double universal male elbow, so both the tube side and the thread side swivel. The 3/8 in thread arrives with sealant applied.
A PL elbow is rigid once installed - the hose must leave at one fixed angle. The PHW1003 adds a second pivot at the thread, so you can correct alignment errors between the port and the hose route without bending tube or re-tightening. That two-way adjustment also means you can unscrew and re-orient the fitting after panel assembly without disturbing the tube connection.
