About the Airtac PHW F Thread Swivel Tee Fitting PHW401D-S
The PHW401D-S is an AirTAC double universal male elbow from the PHW one-touch series. It joins Dia 4 mm soft nylon or polyurethane tubing to a 1/8in PT male thread, and its two swivel stages let the elbow pivot in two planes, so the tube can leave at almost any angle you route it. To connect, push the tube squarely into the chuck until it bottoms out; the stainless spring gasket and collet grip it instantly, and pressing the release ring frees it again.
This is the -S variant, which means the male stud is Stainless steel 304; the body itself remains PBT, finished black here because the D suffix on the PHW series changes the body colour, unlike on PC and POC where it only changes the release button. The resin-line ratings are unchanged by the stainless option: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. AirTAC ships threaded studs with sealant already applied, so no extra 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 PHW401D-S Is Used
CNC coolant and air-blast nozzles
On a machining centre, the nozzle arm gets re-aimed for every new part. The double swivel of the PHW401D-S lets an operator re-angle the Dia 4 air-blast line after the fitting is installed, without unscrewing the 1/8in stud or kinking the tube.
Plating-line rinse stations
Electroplating and rinse tanks throw acidic mist at steel fittings. Here the SUS304 stud on the PHW401D-S resists that atmosphere where a plain brass stud would stain, while the compact Dia 4 elbow feeds a small rinse or purge nozzle.
Welding-cell end effector
A robotic welder's gripper often needs its sense-air or separator pulse fed in from an angle the fixture designer did not predict. The PHW401D-S pivots in two planes, so the Dia 4 tube can be routed cleanly around the torch dress pack.
Is the Airtac PHW F Thread Swivel Tee Fitting PHW401D-S the Right Part?
Dia 4 is the smallest tube this series offers, and with PHW there is no M5 option, so 1/8in is the only thread available at this bore. The next size up is the PHW601D-S at Dia 6 on the same 1/8in thread; if you instead need a 1/4in thread, note that the PHW ladder starts that thread at Dia 6 (PHW602D-S), so a Dia 4 tube can never pair with 1/4in. Match the thread to the component port, not to habit. Remember that tube OD must match the fitting exactly: a Dia 4 one-touch will not seal on 6 mm or 1/4in tubing. If you only need one swivel plane, the plain PH universal elbow is the simpler part; choose PHW when the tube entry angle has to be set after the fitting is screwed down.
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 PHW401D-S FAQ
It is a double universal male elbow one-touch fitting for Dia 4 mm soft nylon or polyurethane tube with a 1/8in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it holds vacuum to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. The stud is SUS304 stainless steel and the body is black PBT.
No. On the PHW series the -S option makes the male thread stud SUS304; the body stays PBT and the internal chuck and spring gasket keep their standard construction. Pressure, vacuum, temperature ratings and every dimension are identical to the standard PHW401D, so you are buying corrosion resistance on the exposed thread, not a re-rated part.
