About the Airtac PHW F Thread Swivel Tee Fitting PHW804D-S
The PHW804D-S is AirTAC's double universal male elbow in the one-touch range, joining Dia 8 mm soft nylon or polyurethane tube to a 1/2in PT male thread. Unlike a fixed PL elbow, the PHW gives you two degrees of freedom: the threaded stud can be screwed into the port at any clock position, and the tube-side joint swivels independently, so the tubing always leaves the fitting in the direction you want. Push the tube home and the internal chuck grips it; press the release ring to free it.
This is the -S variant: on the PHW family the SUS304 stainless steel goes into the stud, the part that bites into the port and sees the wash-down or corrosive atmosphere, while the PBT body, POM release button, aluminium guide, stainless spring gasket and NBR O-ring stay exactly as the standard part. Ratings are unchanged: 0 to 1.0 MPa working, 1.5 MPa proof, -750 mmHg vacuum, -20 to +70 C. The PT thread arrives with sealant already applied; no PTFE tape is needed.

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.

Fitting & Sealing Notes
- check Cut the tube square and clean before pushing it home, or the seal will leak.
- check Push until it stops, then pull back to check the chuck has gripped.
- check To release, press the collet ring fully in and pull the tube out.
- check Threaded parts arrive with sealant on the thread; M5 sizes use a sealing gasket.
- check Match the tube OD exactly - a 6 mm fitting will not hold 1/4" tube.
Where the Airtac PHW F Thread Swivel Tee Fitting PHW804D-S Is Used
Rotary indexing table actuator
On an indexing dial the cylinder port rotates with the table, so a rigid elbow would twist its tubing. The PHW's swivelling tube joint lets the Dia 8 mm hose leave straight down regardless of where the port stops.
Wash-down conveyor corner on a bottling line
In rinse zones the port thread is what corrodes first. The SUS304 stud on this elbow resists the splash zone, and the double-universal shape turns the Dia 8 mm tube around a tight frame corner without kinking.
Clamp fixture on a semi-automatic palletiser
Clamp cylinders sit at odd angles inside machine framing. Screwing the 1/2in PT stud in at whatever rotation the port offers, then swivelling the tube side, removes the need for extra hex-nipple elbows.
Is the Airtac PHW F Thread Swivel Tee Fitting PHW804D-S the Right Part?
On a 1/2in PT thread the PHW ladder runs Dia 8, 10 and 12, so Dia 8 is the smallest tube this thread takes - there is no Dia 6 option below it on 1/2in. If you step up, the next part is the PHW1014D-S for Dia 10 mm tube, which lowers flow resistance on longer runs to a distant actuator. To drop to Dia 6 mm you must also drop the thread to 3/8in, where the PHW supports 6, 8, 10 and 12. Remember tube OD must match exactly: a Dia 8 one-touch will not seal on 1/4in (6.35 mm) imperial tube. If you actually need to pass the connection through a panel wall, a PMF bulkhead connector is the right shape instead of an elbow.
Quick checklist
- ✓ Tube outside diameter matches exactly
- ✓ Thread size and standard match the port
- ✓ Working pressure within 0 - 1.0 MPa (0 - 10 kgf/cm2)
- ✓ Temperature within -20 to +70 °C
Airtac PHW F Thread Swivel Tee Fitting PHW804D-S FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting joins Dia 8 mm soft nylon or polyurethane tube to a 1/2in PT male thread. In this -S version the stud is SUS304 stainless steel; the body is PBT with a POM release button, aluminium-alloy guide, stainless spring gasket and NBR O-ring. The D suffix makes the body black.
AirTAC applies the SUS304 upgrade differently per family. On PHW-type threaded elbows the stainless part is the stud, the metal thread that screws into the port and is exposed to the environment, while the body remains PBT. This keeps the swivel mechanism light and the ratings identical to the standard version. Only the PC and POC straight connectors get a full stainless body in the -S line. Never re-rate a -S part - its pressure and temperature figures match the grey or black original exactly.
