About the Airtac PHW F Thread Swivel Tee Fitting PHW804
The PHW804 is an AirTAC PHW double universal male elbow, a resin one-touch fitting that takes Dia 8 mm soft nylon or polyurethane tube into a 1/2 inch PT male thread. What sets PHW apart from the single-swivel PH is that both ends articulate: the threaded stud rotates in the elbow body and the elbow itself pivots on the tube chuck, so the fitting can be oriented around a corner after both connections are made. Push the tube home and the stainless spring gasket and chuck grip it; press the POM release ring to free it.
This is the resin one-touch line, not the metal BPC family: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. The elbow body is PBT with a brass stud, and the 1/2 inch thread arrives with sealant already applied, so it goes straight into the port without extra tape or compound.

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 PHW804 Is Used
Robotic welding cell wrist feed
On a six-axis welder, the air drop to the torch cleanup cylinder has to clear the counterbalance housing. A double universal elbow lets the fitter torque the 1/2in PT stud into the manifold first and then swing the tube leg to follow the wrist sweep without kinking the hose.
Packaging machine guard corner
Carton sealing machines often tuck the case-clamp cylinder behind a folded sheet-metal guard. PHW804 turns the 8mm feed line around the frame member in one fitting, and because the thread end swivels independently the port side can be tightened blind through an access slot.
Palletiser vacuum generator drop
A cartesian palletising head feeds its venturi generator through a corner bracket where a rigid bend would clash with the Z-axis plate. The 8mm bore matches the generator inlet tubing, and the two-articulation body absorbs the small misalignment between frame and gantry weldments.
Is the Airtac PHW F Thread Swivel Tee Fitting PHW804 the Right Part?
On the PHW ladder a 1/2 inch thread exists only in Dia 8, Dia 10 and Dia 12, so the PHW804 is the smallest tube you can pair with this port size - there is no Dia 6 or Dia 4 option at 1/2 inch, plain and simple. Stepping up to PHW1004 moves the bore to 10 mm and gives noticeably more feed capacity to the actuator on the far end; at 8 mm the bore is the throttle point, so match it to the cylinder port rather than upsizing the thread alone. If your port is actually 3/8 inch, PHW803 covers the same 8 mm tube one thread size down.
Two checks before ordering: the port must be PT (this catalogue documents PT only - do not order this code expecting a G or NPT form), and the tube must be exactly 8 mm OD. A one-touch chuck holds only the diameter it was cut for, so 5/16 inch or 1/4 inch tube will not seal in a Dia 8 pocket. Also note that PHW is never made in M5; the smallest thread in the series is 1/8 inch, which is why 1/2 inch sits at the top of the range.
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 PHW804 FAQ
It is a PHW double universal male elbow for Dia 8 mm tube with a 1/2 inch PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), and proof pressure 1.5 MPa. Operating temperature range is -20 to +70 C. The body is PBT with a brass stud, the release button and chuck are POM, the spring gasket is stainless and the O-ring is NBR. It runs on soft nylon or polyurethane tube, and the thread is supplied with sealant pre-applied.
No. The chuck in a Dia 8 one-touch fitting grips only 8 mm OD tube; there is no approved adapter to downsize inside the pocket, and 6 mm tube will leak or blow out under pressure. On the 1/2 inch PHW thread the smallest tube offered is Dia 8. If your line is genuinely 6 mm, move to a smaller thread size where the Dia 6 part exists in this series, such as PHW603 for a 3/8 inch port, or step the tube up to 8 mm at the manifold.
