The AirTAC PHW F Thread Swivel Tee Fitting PHW802-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 PHW802-S is AirTAC's double universal male elbow from the one-touch fitting range, sized for 8 mm OD soft nylon or polyurethane tube on a 1/4 in PT male thread. Unlike a fixed PL elbow, the PHW swivels at both the thread and the tube head, so the run can be aimed at any angle after the thread is tightened. Push the tube home and the internal chuck grips it; press the release ring to free it.
The -S suffix means the stud that carries the thread is stainless steel 304, while the body remains the standard PBT construction - a point worth checking on drawings, because the shape and dimensions are identical to the grey PHW802. Ratings are unchanged from the resin line: 0-1.0 MPa working, 1.5 MPa proof, -750 mmHg vacuum, -20 to +70 C. The 1/4 in thread arrives with sealant applied, ready to wind into a PT port.

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.

The SUS304 stud resists acid splash and rinse mist around electroplating tanks, and the double swivel lets operators re-aim rinse nozzles without breaking the 1/4 in thread seal.
Swing clamps rotate through an arc, so a fixed elbow would twist its own tubing. The PHW swivel at both ends absorbs the rotation while feeding 8 mm line from a 1/4 in manifold port.
On packaging conveyors hosed down between shifts, the stainless stud shrugs off caustic spray at the valve manifold, and the elbow turns the 8 mm drop line toward the tighten actuator at whatever angle the guard allows.
On the PHW ladder a 1/4 in thread is offered in Dia 6, 8 and 10, so PHW802-S sits mid-ladder: PHW602-S drops to 6 mm tube for lighter cylinder circuits, PHW1002-S steps to 10 mm where the same 1/4 in port feeds a larger bore actuator. Step down for compact tooling, up for shorter fill times on longer runs. Check the thread first: on 1/8 in ports the PHW only goes up to Dia 8, so an 8 mm tube with an 1/8 in port is also a valid PHW801-S rather than a reason to change tube.
The double swivel earns its keep where a standard elbow cannot be oriented without side-loading the thread - articulating fixture arms, pivoting guards, repositioned sensor lines. If no angle is needed, a plain PL802-S costs less. Tube OD must match exactly: this chuck grips 8 mm only, not 5/16 in imperial tube.
Quick checklist
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum to -750 mmHg (10 Torr), operating temperature -20 to +70 C. It joins 8 mm OD soft nylon or polyurethane tube to a 1/4 in PT male thread with sealant pre-applied. The -S suffix puts a SUS304 stainless stud on the standard PBT body; ratings and dimensions are identical to the grey PHW802.
Only the threaded stud is SUS304 on PHW-family -S models - the elbow body itself stays PBT, so it is a corrosion-resistant thread interface, not a solid stainless fitting. That makes it the right choice where spray or condensation attacks the exposed thread at the manifold, but for a fully stainless body on a straight run you would move to a -S PC or POC connector instead.
