The AirTAC PHW F Thread Swivel Tee Fitting PHW802D-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 PHW802D-S is an AirTAC PHW double universal male elbow: a one-touch fitting that joins Dia 8 mm soft nylon or polyurethane tubing to a 1/4 in PT male thread, with a swivel at both the thread end and the tube end. Because the two joints rotate independently, the elbow can absorb misalignment in two planes, so the tube run enters the port square even when the port is not lined up with the piping direction.
This is the stainless -S build of the resin and brass PHW family. On the PHW prefix, SUS304 goes into the male stud while the body stays glass-reinforced PBT, finished in black here because on this series the D suffix changes the body colour, not just the button. The fitting belongs to the standard resin spec profile: 0 to 1.0 MPa working pressure, 1.5 MPa proof pressure, -20 to +70 C, and -750 mmHg vacuum. To connect, push the tube firmly into the chuck until it bottoms out; the stainless spring gasket and POM chuck grip it, and pressing the release ring frees it again. The 1/4 in thread arrives with sealant already applied.

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 spot-welding robot, the clamp cylinder sits on a moving arm while the air manifold is fixed to the base. The double swivel of the PHW802D-S lets the 8 mm supply line enter the port at the angle the arm actually travels, instead of fighting the hose every cycle.
A rotary index table rotates the fixture under a fixed suction head, twisting any rigid piping between them. This elbow's two independently swivelling joints take up that rotation, keeping a Dia 8 vacuum or blow-off line connected without pre-loading the tube.
On a food-plant conveyor where the cylinder ports are caustic-washed daily, the SUS304 stud on this fitting stands up to the splash zone better than bare brass, and the black PBT body wipes clean. The tube itself remains the temperature limit at high wash temperatures.
On the 1/4 in rung of the PHW ladder the tube sizes are Dia 6, 8 and 10, so the neighbours of this part are PHW602 (Dia 6, for lighter lines like sensor or small-gripper circuits) and PHW1002 (Dia 10, when the same port has to feed a higher-consumption cylinder). Stepping up or down changes only the bore and grip range, so the flow capacity tracks the tube, not the fitting. If your port is not 1/4 in, Dia 8 is also offered on the 1/8 in (PHW801), 3/8 in (PHW803) and 1/2 in (PHW804) threads - but never on M5, which the PHW range does not carry.
Match the thread to the port thread, not the tube: a 1/4 in port takes this stud directly, and the PT thread sealant on arrival does the sealing. Note that a Dia 8 chuck will not hold 1/4 in (6.35 mm) tube - the outside diameter must be exactly 8 mm. If you need the swivel at the port but a straight shot into a panel wall, compare the PLM bulkhead elbow instead.
Quick checklist
Working pressure 0 to 1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, negative pressure down to -750 mmHg (10 Torr), and a temperature range of -20 to +70 C. The tube side accepts Dia 8 mm soft nylon or polyurethane tubing on a one-touch chuck; the thread side is a 1/4 in PT male stud in SUS304 stainless. The double-universal body is black PBT, and the release button and chuck are POM with an NBR O-ring seal. These ratings are identical to the non-stainless PHW802.
AirTAC applies stainless differently by family. On the PHW elbows, only the male stud is SUS304; the body stays PBT, and the dimension tables match the standard version exactly. A fully stainless body is offered only on the PC and POC straight connectors in the -S line. So you get a corrosion-resistant thread interface at the port, where splash and wash-down actually land, while keeping the same pressure, vacuum and temperature figures as the brass-stud original. No food, medical or corrosion-class certification is published for this part.
