About the Airtac PH-1 Hex Head Toggle Joint PH804D-S
The PH804D-S is an AirTAC PH universal male elbow: a 90 degree one-touch fitting that pushes a Dia 8 mm soft nylon or polyurethane tube into a 1/2in PT male thread. The universal part of the name matters - the threaded stud swivels, so you can thread the fitting into the port first and then swing the tube leg to whatever angle the hose run needs. Push the tube home and the internal chuck grips it; press the release ring and it lets go.
This is the -S stainless variant. On the PH family that means the stud is SUS304 while the elbow body remains PBT, so the corrosion-resistant advantage sits exactly at the threaded interface where moisture and washdown splash collect. The D suffix gives the body in black. Ratings are identical to the standard version: 0-1.0 MPa working, 1.5 MPa proof, -20 to +70 C, and -750 mmHg vacuum.

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 PH-1 Hex Head Toggle Joint PH804D-S Is Used
Rotary indexing table air legs
On a rotary indexing table the air ports rotate with the dial, so a fixed elbow rarely lines up with the hose drop. The PH804D-S swivelling stud lets the fitter thread in and then set the Dia 8 tube leg at the exact approach angle the reel needs.
Plating line rinse station
Rinse and spray stations on electroplating lines sit in constant acidic mist. The SUS304 stud on this fitting keeps the threaded connection into the panel or manifold from corroding, where an unplated brass stud would weep and stain.
Clamping fixture under a machine guard
Pneumatic clamps mounted inside a sheet-metal guard often leave the port pointing the wrong way once the bracket is welded. A universal elbow at the port lets the Dia 8 polyurethane drop to the valve manifold without repositioning the clamp itself.
Is the Airtac PH-1 Hex Head Toggle Joint PH804D-S the Right Part?
At the 1/2in thread position the PH ladder runs Dia 8, 10 and 12 - so Dia 8 is the smallest tube this thread takes, and the next step up is PH1004-S for a Dia 10 line. If your port is 3/8in or 1/4in instead, the Dia 8 tube is still served by PH803-S and PH802-S respectively, and those larger threads accept more tube sizes further down the ladder. Match the thread to the port thread, not to the hose; the tube side must match the OD exactly, so a Dia 8 fitting will never hold 1/4in (6.35 mm) tube even though the numbers look close.
Choose the universal elbow shape over a fixed PL male elbow when the port orientation is awkward or cast - a manifold port facing sideways, a cylinder port rotated under a guard, or any build where you want to hand-align the tube leg after installation rather than fight the thread direction.
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 PH-1 Hex Head Toggle Joint PH804D-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. It joins Dia 8 mm soft nylon or polyurethane tube to a 1/2in PT male thread. The stud is SUS304 stainless steel and the elbow body is PBT in black; the stainless variant does not change any pressure or temperature rating.
No. The one-touch chuck inside the PH804D-S is machined for exactly Dia 8 mm tube OD and will not seal or grip 10 mm or 6 mm tube. If your line is Dia 10, order PH1004-S on the same 1/2in thread. For a genuine change of tube diameter in-line, use a PG different-diameter straight union instead of forcing a mismatched tube into a chuck.
