About the Airtac PH-1 Hex Head Toggle Joint PH1204
The PH1204 is an AirTAC PH universal male elbow, the swivel-bodied 90 degree fitting that joins Dia 12 mm soft nylon or polyurethane tubing to a 1/2in PT male port. To make the joint, push the tube straight into the chuck until it bottoms out - the stainless spring gasket and POM chuck grip the OD instantly - and press the release ring to free it again. Because the male stud can be rotated in the elbow body, the thread goes into the port first and the tube leg then swings to whichever direction the run needs.
This is a resin line part, so it carries the full resin ratings: 0 to 1.0 MPa working pressure (0 to 10 kgf/cm2), 1.5 MPa proof pressure, -750 mmHg vacuum and -20 to +70 C. The threaded parts are PBT with a brass stud, and the 1/2in PT taper arrives with sealant already applied on the thread, so no additional tape or paste is needed at assembly.

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 PH1204 Is Used
Stamping cell clamp cylinders
Large clamp cylinders on press tooling often have ports pointing into the die space; the PH1204 threads in at 90 degrees and its swivel stud lets the Dia 12 supply line drop vertically clear of the ram.
Rotary indexing tables
On a packaging machine indexing table the fitting's threaded end fixes to the manifold port while the tube leg rotates to line up with the routing channel, so the 12 mm feed reaches the table's large-bore actuator without twisting the hose.
CNC router vacuum clamping
Vacuum hold-down boards on CNC routers draw through big-bore lines; with a -750 mmHg (10 Torr) rating this Dia 12 elbow serves as the corner fitting between the pump manifold and the clamp circuit.
Is the Airtac PH-1 Hex Head Toggle Joint PH1204 the Right Part?
On the PH 1/2in row the ladder runs Dia 8, 10, 12, so the step down from this fitting is the PH1004 with a Dia 10 bore - one size less flow capacity for a smaller actuator port - and Dia 12 is the largest tube the PH 1/2in thread takes, so there is nothing above it on this thread. If your port is 3/8in, the PH1203 still accepts Dia 12 tube because PH 3/8in runs 6 through 12; that pairing keeps the big bore while dropping the thread. Match the thread to the actual port on the valve or cylinder, not to the pipe size upstream of it.
Tube OD must match exactly: the chuck in this fitting grips 12 mm and will not seal on 1/2in (12.7 mm) or any other nominal tube. If you need the joint to pass through a panel rather than turn a corner on it, a PMF bulkhead connector is the shape to reach for instead; if you need to step two tube sizes together without a thread, a PG different-diameter union does that job.
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 PH1204 FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), proof pressure 1.5 MPa, negative pressure down to -750 mmHg (10 Torr), and a temperature range of -20 to +70 C. The fitting takes Dia 12 mm soft nylon or polyurethane tube on a 1/2in PT male thread.
Yes - that is the point of the PH universal shape. The male thread is fixed by its taper and the pre-applied sealant, but the elbow body swivels on the stud, so you can tighten the thread fully and then swing the tube leg to the exact direction your run needs before pushing the Dia 12 tube home.
