About the Airtac PH-1 Hex Head Toggle Joint PH804-S
The AirTAC PH804-S is a universal male elbow from the one-touch fitting range: it terminates Dia 8 mm soft nylon or polyurethane tube onto a 1/2 in PT male thread. Universal means the threaded stud swivels through a full circle before you tighten it, so the tube leaves the elbow pointing exactly along your hose run instead of being bent sideways against the seal.
The -S suffix fits a SUS304 stainless-steel stud to this elbow; the elbow body stays PBT, with a POM release button, aluminium-alloy guide and NBR O-ring as on the standard part. Ratings are not re-rated by the stainless option: 0-1.0 MPa working pressure, 1.5 MPa proof, -20 to +70 C and -750 mmHg vacuum. Push the tube home and the internal chuck, backed by a stainless spring gasket, grips it; press the release ring to free it again.

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 PH804-S Is Used
Plating and phosphating lines
Acid mist around electroplating tanks attacks brass studs quickly. The SUS304 stud on the PH804-S suits air feeds to lift and transfer cylinders near the tank line, and the swivel lets the Dia 8 tube drop vertically to the port.
Rotary indexing tables
On a rotary feeding station with a 1/2 in PT port under the turntable, rotate the stud so the Dia 8 tube exits sideways clear of the rotating plate instead of twisting the hose every index.
Marine engine rooms
Salt-laden air in a boat engine bay corrodes plated brass fast. A Dia 8 stainless-stud elbow feeding a bilge alarm actuator or deck-wash air line from a 1/2 in threaded port holds up far better.
Is the Airtac PH-1 Hex Head Toggle Joint PH804-S the Right Part?
On a 1/2 in thread, Dia 8 is the smallest tube PH is offered in - the ladder goes PH804-S, then PH1004-S and PH1204-S at Dia 10 and Dia 12, which give a larger bore for long or high-consumption runs. If the port you are threading into is 3/8 in, PH803-S carries the same Dia 8 tube on a smaller stud and is worth checking before you drill or tap for 1/2 in.
Match the tube exactly: the Dia 8 chuck will not seal 6 mm or 10 mm tubing, and the release will not grip an off-size at all. If what you actually need is to pass the thread through a panel wall rather than swivel at a port, a bulkhead shape is the wrong family here - but the PH stud does solve orientation problems nothing else in the ladder can.
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 PH804-S FAQ
It is a PH universal male elbow joining Dia 8 mm tubing to a 1/2 in PT male thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum down to -750 mmHg (10 Torr), operating temperature -20 to +70 C. Tubing is soft nylon or polyurethane. The -S suffix makes the threaded stud SUS304 stainless steel; the elbow body remains PBT and none of the pressure or temperature figures change from the standard PH804.
No. AirTAC supplies these threaded one-touch fittings with sealant already applied to the PT thread, so it seals on first assembly. Because the universal stud swivels, hold the hex flats with a wrench and stop tightening once the elbow points the way you want - over-torqueing past that position wastes the adjustment the shape exists for.
