The AirTAC Airtac PHW F Thread Swivel Tee Fitting PHW1003D 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 PHW1003D is an AirTAC double universal male elbow from the resin one-touch range: a 3/8in PT male stud at one end, then two articulating joints that let the tube exit swing through two planes before pointing the way you need it. It joins Dia 10 mm soft nylon or polyurethane tubing to the port, and the D suffix on this series means the body itself is moulded in black, not just the release button.
Connection is the usual one-touch action: push the Dia 10 tube fully home and the stainless spring gasket and chuck grip it against the NBR O-ring seal; press the POM release ring and the tube pulls free. The stud thread arrives with sealant pre-applied, so it seals on the PT port without extra tape. This is the resin spec profile: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C, with a PBT body on a brass stud.

Weld guns swing and rotate through the cycle, so a rigid elbow at the cylinder port fatigues the tube fast. The two-plane swivel of the PHW1003D lets the Dia 10 feed line follow the gun body as it articulates.
Where a 3/8in valve manifold port sits behind a coil of wiring, the double swivel lets the 10 mm tubing drop straight down past terminal blocks instead of sweeping a wide fixed-radius bend across the panel.
Feed lines to a rotating dial have to change direction twice - vertical off the fitting, then horizontal into the fixture. A PHW1003D makes both turns in the fitting itself, keeping the Dia 10 tube clear of the guard.
On the 3/8in thread ladder for PHW, the neighbouring tube sizes are Dia 8 (PHW803) below and Dia 12 (PHW1203) above. Stepping down to 8 mm trims the bore for lighter-acting cylinders or shorter runs; stepping up to 12 mm suits lines feeding larger-bore actuators where you want to keep air velocity down. Both exist on this thread - PHW in 3/8in carries the widest tube ladder of the universal elbows at 6, 8, 10 and 12 mm.
Check the port before you commit to the thread: the same Dia 10 tube is also available as PHW1002 on a 1/4in PT stud or PHW1004 on a 1/2in PT stud. Match the stud to the component port, not the other way round, and remember the tube OD must match exactly - a Dia 10 fitting will not seal on 3/8in or 12 mm tube. If the tube exit only needs to bend once, the single universal elbow PH or PHF is the simpler part; PHW earns its cost when two direction changes are needed. Note that PHW has no M5 option at all - the series starts at 1/8in.
Quick checklist
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting accepts Dia 10 mm soft nylon or polyurethane tube on a 3/8in PT male thread, with sealant pre-applied to the stud. It belongs to the resin one-touch family, so it is the 1.0 MPa / 70 C profile, not the 0.9 MPa / 150 C metal BPC line.
PH swivels in one plane only, so the tube exit can point anywhere on a single cone of movement. PHW adds a second articulating joint, letting the outlet turn through two planes - useful where the tube must first clear the port and then change direction again to reach the run. Both take the same one-touch chuck, and both in this size use the same resin construction on a brass stud; PHW simply gives the installer an extra degree of freedom at the cost of a slightly longer body.
