The AirTAC Airtac PHW F Thread Swivel Tee Fitting PHW602-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 AirTAC PHW602-S is a double universal male elbow in the PHW one-touch range: it joins 6 mm outside diameter soft nylon or polyurethane tube to a 1/4 in PT male port, and unlike a fixed elbow it swivels at two points, so the thread axis and each tube leg can all sit at angles that suit the machine. You push the tube home until the stainless spring gasket and chuck grip it, and press the release ring to free it.
On this -S variant the SUS304 stainless steel is in the stud, which is the part that threads into the port and takes splash and condensation; the elbow body remains PBT with a POM release button, aluminium-alloy guide and NBR O-ring. Ratings are the standard resin profile: 0-1.0 MPa working, 1.5 MPa proof, -750 mmHg vacuum, -20 to +70 C. AirTAC ships threaded parts with sealant already applied on the PT thread.

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 small robotic pick-and-place unit, the gripper head rotates between stations, so a fixed elbow would twist its tubing off. The PHW602-S double swivel feeds 6 mm line into the head at whatever angle each station leaves it, and the SUS304 stud stands up to cutting-fluid mist around the cell.
At a plating or rinse tank, overhead spray and acid fumes corrode bare brass threads on manifold studs. Here the stainless stud threads into the panel-mounted manifold while both tube legs drop to 6 mm acid-mist extraction jets, and the swivel joints let the jets be aimed at the work.
A reject gate on a bottling conveyor needs its air connection to approach from an awkward angle between the guide rails and the frame. The PHW602-S threads into a 1/4 in port on the compact cylinder and swivels both 6 mm tube legs clear of the rail, so nothing fouls as bottles pass.
On the PHW ladder with a 1/4 in thread, Dia 6 is the smallest tube made, so there is no smaller sibling on this same thread; the step down is PHW601, the same 6 mm tube on a 1/8 in thread for tighter ports. The step up is PHW802, an 8 mm tube on 1/4 in, which suits runs where you want more bore for longer lines. Note that PHW is never offered in M5 at all - the double universal elbow starts at 1/8 in.
Match the thread to the port before anything else: 1/4 in PT is the common cylinder and valve port in this size class. Tube outside diameter must match exactly, so a Dia 6 fitting will not grip 1/4 in or 8 mm tube. If you only need the tube to turn, PV or PE may do; choose PHW when the threaded side also has to swivel into position.
Quick checklist
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, negative pressure -750 mmHg (10 Torr), operating temperature -20 to +70 C. It is a double universal male elbow taking Dia 6 mm outside diameter soft nylon or polyurethane tube on a 1/4 in PT male thread, with the stud in SUS304 stainless steel and the elbow body in PBT.
No. On the PHW family the -S suffix means the stud is SUS304; the elbow body stays PBT with a POM release button and NBR O-ring. The dimensions are identical to the standard PHW602, so it is a direct swap where you want corrosion resistance at the threaded interface rather than a full stainless body.
