About the Airtac PHF Tandem Toggle Joint PHF1204-S
The PHF1204-S is the SUS304-stud version of AirTAC's PHF universal female elbow, joining Dia 12 mm soft nylon or PU tubing to a 1/2 inch PT female port. Push the tube into the chuck until it seats, and the stainless spring gasket and NBR O-ring lock the joint; press the POM release ring and the tube slides back out. Because the thread is female with a rotating nut, you can tighten the port first and clock the elbow to face the run you actually need - no more fighting the sealant line on a male stud.
One material point that matters on this SKU: on PHF parts the -S suffix means the mounting stud is SUS304 while the body itself stays PBT, and the pressure and temperature figures are identical to the grey standard version - 0-1.0 MPa working, 1.5 MPa proof, -750 mmHg vacuum, -20 to +70 C. AirTAC publishes no separate stainless rating, so treat this as a corrosion-upgrade on the wetted stud, not a re-rated fitting.

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 PHF Tandem Toggle Joint PHF1204-S Is Used
Electroplating transfer cylinder
On a plating line, the SUS304 stud resists splash-zone attack from acid mists around the rinse-tank transfer cylinder, while the swivel female nut lets the drop leg reach the port at the angle the tank frame dictates.
Fish-processing wash-down gate
A gate actuator on a fish-processing conveyor sits under daily hose-down. The PT female port connects to the valve manifold stud, and the Dia 12 bore carries the volume a 50 mm bore cylinder draws at stroke end.
Brewery rinse-carousel valve block
On a bottle-rinse carousel, the 1/2 inch female nut clocks the elbow over the rotating valve block after the manifold is torqued down, so the drop tube to the spray head exits vertically instead of fouling the guard.
Is the Airtac PHF Tandem Toggle Joint PHF1204-S the Right Part?
This is the top of the PHF ladder at 1/2 inch. Step down to PHF1004 (Dia 10 mm on the same 1/2 inch thread) if your actuator feeds are lighter and you want a slimmer elbow body, or hold Dia 12 and drop the port to PHF1203 (3/8 inch PT) on a crowded manifold. There is no Dia 16 tube in this catalogue, so Dia 12 is where the size ladder ends - plan your cylinder bore sizing with that ceiling in mind.
Match the 1/2 inch female nut to a male PT stud on the valve or cylinder. Remember the tube OD must match exactly: a Dia 12 chuck will not grip 1/2 inch nominal hose or a 10 mm tube, and no adapter inside this series converts between inch and metric ODs. If the port sits behind sheet metal, a bulkhead shape such as PMF is the better answer than forcing an elbow against the panel.
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 PHF Tandem Toggle Joint PHF1204-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum down to -750 mmHg (10 Torr), and a service temperature of -20 to +70 C. This SKU takes Dia 12 mm soft nylon or polyurethane tube on a 1/2 inch PT female thread. The stud is SUS304 and the body is PBT; the ratings are the same as the standard grey PHF1204.
Only as far as AirTAC publishes: on PHF parts the -S suffix makes the stud SUS304 while the elbow body remains PBT, and nothing about pressure, temperature or dimensions changes from the standard version. AirTAC publishes no surface-finish, passivation or certification data for the stainless line, so any wash-down spec should be validated on site rather than assumed from the suffix.
