The AirTAC Airtac PHW F Thread Swivel Tee Fitting PHW1002D-S 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 PHW1002D-S is an AirTAC double universal male elbow: a one-touch fitting that joins Dia 10 mm soft nylon or polyurethane tubing to a 1/4 in PT male port, with a swivel joint at BOTH ends rather than just the thread. Push the tube past the guide into the chuck and the stainless spring gasket grips it against internal pressure; press the POM release ring and the tube frees for repositioning. Because both the thread end and the tube end pivot, you can route the incoming line at any angle without fighting the fitting into alignment. The trailing -S means the male stud is SUS304 stainless steel; on the PHW shape the main body stays glass-reinforced PBT, so this is a corrosion-resistant connection point rather than an all-stainless part. The D suffix gives the body in black instead of the standard grey.
This belongs to the resin/brass one-touch profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg, proof pressure 1.5 MPa, and a service temperature of -20 to +70 C. The 1/4 in PT thread arrives from AirTAC with sealant already applied to the male thread, so it seals on tape-free assembly; the release button, chuck and O-ring keep their standard POM and NBR construction on the -S version.

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.

On a robotic gripper arm, the vacuum or actuation line enters at an angle that changes with the wrist pose. The PHW1002D-S swivels at both the 1/4 in PT port and the 10 mm tube end, so the hose tracks the motion instead of loading the fitting sideways.
Rotary indexing tables carry cylinder ports that point wherever the turret stops. A double universal elbow at each Dia 10 station lets the fixed manifold plumbing stay straight while the fitting self-aligns to the rotating port.
Guide-rail width cylinders get repositioned and re-plumbed during changeover. The black PBT body resists knock-on damage in the frame, and the 10 mm bore feeds compact air cylinders without throttling their cycle speed.
Within the 1/4 in PT row of the PHW ladder, the sizes available are Dia 6, 8 and 10, so this Dia 10 version is the LARGEST tube the 1/4 in thread takes. Stepping down to PHW0802 gives you a lighter 8 mm line and slightly better access in tight tooling; there is no larger tube on 1/4 in. If the circuit later grows to 12 mm, you must move the thread up as well, because 1/2 in on PHW starts at Dia 8 and PHW1204 is the natural next step. Whichever way you go, the tube OD must match the fitting exactly: a Dia 10 chuck will not seal on 3/8 in or 5/16 in tube, and forcing a near-size in is the most common cause of a slow leak on one-touch joints.
Choose the double-swivel PHW shape over the single-swivel PH or PHF when the port orientation AND the incoming hose direction are both outside your control, which is typical on rotating or adjustable subassemblies. If you actually need to join two tube runs with no thread at all, that is the PV union elbow instead, a different series entirely.
Quick checklist
Working pressure 0-1.0 MPa (0-10 kgf/cm2); vacuum capability -750 mmHg (10 Torr); proof pressure 1.5 MPa; operating temperature -20 to +70 C. Tube size Dia 10 mm (soft nylon or polyurethane), thread 1/4 in PT male. Construction: PBT body in black (D suffix), SUS304 stainless male stud, POM release button and chuck, aluminium-alloy guide, stainless spring gasket, NBR O-ring. Flow is published by AirTAC as a characteristic curve only, tied to the 10 mm bore.
No. On the PHW family, the -S option puts the SUS304 male stud on the threaded end; the elbow body remains PBT, which is why the published pressure, vacuum and temperature figures are identical to the standard PHW1002D. AirTAC publishes no corrosion class, surface finish or certification for the -S line, so it should be specified for corrosion-prone or copper-sensitive mounting points based on the stud material alone, not on a certification claim.
