About the Airtac PH-1 Hex Head Toggle Joint PH803-S
The PH803-S is an AirTAC PH universal male elbow, a one-touch fitting that joins Dia 8 mm soft nylon or polyurethane tubing to a 3/8 in PT male port. Push the tube home and the chuck grips it against a stainless spring gasket with an NBR O-ring behind it; press the release ring and the tube frees off again. Unlike a fixed PL elbow, the PH head swivels on its thread, so you can tighten the 3/8 in connection first and then clock the tube outlet to point exactly where the hose run needs it.
This -S variant keeps the standard PBT body but upgrades the male stud to SUS304 stainless steel, putting corrosion-resistant metal right at the port thread where moisture and splash tend to collect. The rating set is unchanged from the resin line: 0-1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C. The stud ships with sealant already on the thread, so no extra tape or paste is needed at assembly.

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 PH803-S Is Used
Rotary actuator on an indexing table
A rotary cylinder often lands with its port pointing somewhere useless once mounted. The PH803-S swivelling head lets you torque the 3/8 in stud square to the port and then rotate the Dia 8 mm tube outlet around to the hose run.
Compact cylinder inside a machine guard
On a small packaging or assembly machine where the guard skin sits close to the cylinder, a straight connector would force the tube into a hard bend. This elbow turns the run 90 degrees right at the port and frees the routing.
Rinse station on a plating or wash line
Where the fitting sees regular splash and humid air, the SUS304 stud resists corrosion at the port interface, while the PBT body shrugs off the wash-down environment around Dia 8 mm drop lines to rinse guns and small air cylinders.
Is the Airtac PH-1 Hex Head Toggle Joint PH803-S the Right Part?
Within the PH ladder on a 3/8 in thread, the neighbouring sizes are PH603 down at Dia 6 tube, which suits lighter cylinder and sensor lines, and PH1003 up at Dia 10 tube when the branch feeds a larger bore actuator and you want the bigger bore for capacity. If the port in front of you is 1/4 in rather than 3/8 in, the same Dia 8 tube is served by PH802 on the PH row. Pick the elbow only after confirming the port size, because a PT thread with sealant will not forgive a half-size match.
Choose a universal elbow over a straight PC or a fixed PL when the fitting must be oriented after installation, such as a port that faces an awkward direction once the actuator is mounted. And remember the tube OD has to match exactly: a Dia 8 chuck will not hold 10 mm or 1/4 in tube reliably, no matter how close it looks.
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 PH803-S FAQ
Working pressure is 0-1.0 MPa (0-10 kgf/cm2) with a vacuum capability of -750 mmHg (10 Torr). Proof pressure is 1.5 MPa. The service temperature range is -20 to +70 C. This SKU takes Dia 8 mm soft nylon or polyurethane tube on a 3/8 in PT male thread, with a SUS304 stud on a PBT body. Applying -S changes the stud material only, never the ratings.
No. On PH-series -S parts AirTAC keeps the body in PBT and upgrades only the male stud to SUS304 stainless steel, which is where thread corrosion typically starts. If you need a fitting whose body itself is stainless steel 304, the PC and POC straight connectors in -S form are the parts in this catalogue that do that. Dimensions and ratings are otherwise identical to the standard PH803.
