The AirTAC Airtac PHW F Thread Swivel Tee Fitting PHW1203D 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 AirTAC PHW1203D is a double universal male elbow from the PHW series: a one-touch fitting with a 3/8 in PT male thread at one end, a Dia 12 mm tube port at the other, and TWO pivoting joints instead of one. The thread end and the elbow body each swivel independently, so the male port can be screwed in at whatever angle the machine gives you and the tube run can then be aimed where it needs to go - no bending the pipe to meet the fitting.
This is the resin one-touch profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg, proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. To connect, push the Dia 12 soft nylon or PU tube straight into the port until it bottoms; the stainless spring gasket and POM chuck grip it. Press the release ring and the tube frees. The D suffix on this series makes the whole body black, not just the release button, and the male thread arrives with sealant pre-applied.

On a 12mm-line press or clamp cylinder whose 3/8 in port faces sideways into the frame, the double swivel lets the fitting screw home square and still point the tube run up or out of the way.
Feeding a Dia 12 main drop along a wiring duct in a machine cabinet? The second pivot lets the tube exit parallel to the duct while the thread stays fixed in the manifold port.
When a new guard or cover blocks the original tube path to a packaging machine's actuator, a two-joint elbow re-aims the run around the obstruction without re-machining the port.
On the PHW 3/8 in ladder the sizes run Dia 6, 8, 10 and 12, so PHW1203D sits at the TOP: one step down is PHW1003 (Dia 10 tube), which suits smaller-bore cylinders and lighter lines, while this Dia 12 bore is what you pick when the run feeds a large actuator or a main drop. If your port is 1/2 in instead, the same Dia 12 tube exists on that thread as PHW1204 - there is no larger tube to step up to in this series.
Match the 3/8 in PT male to the port before anything else, then let the double swivel do the aligning. And check the tube, not just the fitting: the chuck grips exactly Dia 12 mm. A nominal 1/2 in tube (12.7 mm) will not seal here, and a Dia 10 tube will blow straight past the grip.
Quick checklist
It joins a Dia 12 mm tube to a 3/8 in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, and vacuum capability is -750 mmHg (10 Torr). The operating temperature range is -20 to +70 C. Use soft nylon or polyurethane tube only, and the D suffix means the body and release button are both black.
A single-swivel elbow still forces you to line the tube run up with the fixed elbow body. The PHW1203D has two independent joints - the male thread pivots on the elbow and the elbow pivots on the tube port - so you can tighten the thread at whatever clock angle the port sits and then orient the tube exit freely. The 3/8 in thread also arrives with sealant already applied, so no extra tape or paste is needed.
