About the Airtac PHF Tandem Toggle Joint PHF1204
The AirTAC PHF1204 is a PHF series universal female elbow, the largest tube size AirTAC makes on this prefix. It pushes a Dia 12 mm soft nylon or polyurethane tube into one leg and presents a 1/2in PT female parallel port on the other, turning the air path 90 degrees. Because the female thread can swivel relative to the elbow body, you can tighten the nut onto the port first and then rotate the tube leg to point exactly where the hose run needs it - useful on cast ports whose clocking you cannot choose.
This is a resin-and-brass one-touch fitting on the standard resin spec profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. Installation is the usual one-touch action: push the 12 mm tube squarely into the chuck until it bottoms, and the stainless spring gasket and POM chuck grip it; press the release ring to free it. The PBT threaded housing arrives with sealant already applied, so no extra tape is needed on the 1/2in port.

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 Is Used
Large pneumatic cylinder feed on a press
A 1/2in female port on a compact air cylinder or clamp cylinder can sit at an angle that fights the hose routing. The PHF1204 swivel lets you thread it down solid and then swing the 12 mm supply line clear of the tooling.
Manifold outlet on an injection moulding machine
Mould cooling and core-pull circuits often feed 12 mm polyurethane lines from female-threaded manifold bosses tucked behind platens. A right-angle female elbow shortens the drop and avoids a hose loop that fouls the tie-bar.
Air preparation outlet to a workshop ring main
A filter-regulator-lubricator unit with a 1/2in outlet can feed a 12 mm trunk line straight into a push-in drop legs without adapters, the female swivel absorbing any misalignment of the FRL mounting.
Is the Airtac PHF Tandem Toggle Joint PHF1204 the Right Part?
At 1/2in thread, PHF supports only Dia 8, Dia 10 and Dia 12 tube, so PHF1204 is the top of the ladder: there is no Dia 16 fitting in this catalogue and no larger thread on the PHF prefix. Step down to PHF1004 when the feed line is 10 mm and you want a slimmer hose; step the thread down instead with PHF1203 (12 mm tube, 3/8in female) when the actuator port is smaller but the tubing is already fixed at 12 mm.
Pick a universal female elbow over a fixed PL male elbow whenever the port is female-sealed and its orientation is awkward - a cast manifold boss, a valve outlet facing the wrong way, a cylinder port under a guard. Remember the cardinal rule: tube OD must match exactly. A 12 mm chuck will not seal 1/2in nominal tube and it will not grip 10 mm either.
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 FAQ
The PHF1204 is a PHF universal female elbow with a Dia 12 mm tube connection and a 1/2in PT female thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), proof pressure is 1.5 MPa, it holds vacuum to -750 mmHg (10 Torr), and the rated temperature range is -20 to +70 C. It is designed for soft nylon or polyurethane tube only.
You can - but leave the factory sealant on the thread, which AirTAC applies before shipping. If you prefer your own PTFE tape, remove the existing sealant first so the joint does not become over-thick and stress the female thread. Also note the swivel: tighten the female nut fully before setting the final angle of the tube leg, not after, or you risk backing the sealant joint off.
