About the Airtac PHW F Thread Swivel Tee Fitting PHW601-S
The PHW601-S is AirTAC's double universal male elbow from the resin one-touch range, carrying a Dia 6 tube socket on one end and a 1/8in PT male thread on the other. Unlike a fixed PL elbow, this shape articulates at two separate joints, so the tube path can be set at any compound angle after installation instead of being locked to 90 degrees in one plane only. To make the joint, push the soft nylon or polyurethane tube squarely into the socket until it bottoms out - the internal chuck grips the OD and the stainless spring gasket and NBR O-ring seal it. Pressing the POM release ring frees the tube again.
This is the standard resin pressure profile, not the metal BP line: 0 to 1.0 MPa working, -750 mmHg vacuum, 1.5 MPa proof, and -20 to +70 C. The -S suffix fits a SUS304 stainless stud to the threaded end while the body remains PBT, so it suits mildly corrosive or wash-prone locations without changing the fitting's dimensions or ratings. The 1/8in thread arrives with sealant pre-applied; on PHW parts there is no M5 option, so 1/8in PT is the smallest thread you can order.

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 PHW601-S Is Used
Rotary indexing tables
Feeding cylinders on a rotating dial plate, where the tube must follow the plate's rotation and reach the port at a compound angle no fixed 90 degree elbow can hold.
Robotic gripper lines
Routing 6 mm polyurethane to a gripper cylinder on an articulated arm, with the double swivel absorbing the wrist's two-plane motion instead of the tube doing so.
Conveyor gate actuators
Piping the air cylinder that flips a guide or reject gate on a bottling line, where the guard space forces an angled approach to the 1/8in port.
Is the Airtac PHW F Thread Swivel Tee Fitting PHW601-S the Right Part?
On the PHW ladder at 1/8in thread, only Dia 4, Dia 6 and Dia 8 tubes are offered - this Dia 6 sits in the middle, so PHW401-S steps down to finer 4 mm lines and PHW802-S steps up to 8 mm. Larger threads (1/4in to 1/2in) cover Dia 6 to 12 if you need a bigger port. Match the thread to the port size rather than to the tube: a Dia 6 tube on a small solenoid valve port is a common reason to pick 1/8in. The tube must match the socket exactly - this Dia 6 fitting will not hold 1/4in (6.35 mm) imperial tube, and no shim or wrap fixes that.
Choose the double universal PHW shape over a fixed PL elbow whenever the tube has to approach the port from two directions at once, or when the mating component moves and a rigid 90 degree bend would fatigue the line. If the run only needs one articulation, a single PH universal elbow is lighter on cost; if you need to pass through a panel, look at PMF instead.
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 PHW601-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, and a temperature range of -20 to +70 C. The tube socket takes Dia 6 soft nylon or polyurethane tubing and the male thread is 1/8in PT, pre-coated with sealant. These figures are identical to the standard grey PHW601; the -S suffix changes only the stud material to SUS304.
No - on PHW-family parts the -S variant keeps a PBT body and fittings internals (POM release ring, aluminium-alloy guide, NBR O-ring) and upgrades the threaded stud to SUS304. AirTAC's dimension tables for the -S match the standard part exactly, and the pressure, vacuum and temperature ratings are unchanged, so you can substitute it directly wherever a PHW601 is specified.
