About the Airtac PH-1 Hex Head Toggle Joint PH803D-S
The PH803D-S is an AirTAC PH universal female elbow, a one-touch fitting that joins a Dia 8 mm soft nylon or polyurethane tube to a 3/8in female PT thread. The swivel is the whole point of the shape: the threaded half turns independently of the tube axis, so the female thread can be clocked square to the port while the 8 mm tube runs off in any direction. Push the tube home and the chuck grips it behind a stainless spring gasket; press the release ring and the tube frees again. The D in the code sets the body to black instead of the standard grey.
This -S variant keeps the PBT body and adds a SUS304 stainless stud, so it is a stainless-stud fitting, not a solid stainless part. Ratings follow the standard resin and brass one-touch profile: 0-1.0 MPa working, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof, -20 to +70 C. The female thread receives a male stud from the port or manifold, and threaded forms arrive with sealant already applied.

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 PH803D-S Is Used
Pick-and-place gantry valve manifold
On a pick-and-place gantry the manifold studs often face an awkward angle. The swivelling female thread of the PH803D-S drops onto the stud and is then clocked so the 8 mm polyurethane tube clears the cable chain and the gripper's return stroke.
Pilot-plant rinse skid plumbing
Around a pilot-plant rinse skid the pipework is wet and frequently wiped down. The SUS304 stud at the port and the quick release of the 8 mm tube make filter-regulator and valve rewiring a tool-free job between trial runs.
Cabinet door routing on a packaging machine
Feeding air from a solenoid bank inside a packaging machine cabinet to devices on the door means a bend right at the outlet. The universal elbow points the 8 mm tube along the door hinge side while the 3/8in female thread seats flat on the manifold boss.
Is the Airtac PH-1 Hex Head Toggle Joint PH803D-S the Right Part?
On a 3/8in thread the PH ladder steps from Dia 6 below this SKU to Dia 10 above it, so both a smaller and a larger bore exist without changing the port size. On thread, Dia 8 is also offered at 1/4in (PH goes up to Dia 10 there) and at 1/2in, so a smaller or larger port is likewise available. Match the tube exactly: a Dia 8 chuck will not grip 6 mm or 10 mm tube, and no adapter inside the fitting fixes that. If the connection has to pass through a sheet-metal wall rather than sit on a port, a bulkhead style is the better shape than this elbow.
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 PH803D-S FAQ
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 range of -20 to +70 C. This SKU joins a Dia 8 mm tube to a 3/8in female PT thread with a black PBT body and SUS304 stud. It belongs to the resin and brass one-touch profile, and the -S suffix changes no pressure, vacuum or temperature figure.
No. On PH-family stainless variants only the stud is SUS304; the body remains PBT with the standard POM release button and NBR O-ring. The tube ladder, dimensions and every rating are identical to the grey standard version. AirTAC publishes no corrosion class, passivation spec or certification for the stainless line, so it should be chosen for the stud material itself rather than for a claimed grade.
