About the Airtac PC Threaded Straight Connector PC1204
The AirTAC PC1204 is a PC series one-touch male connector, the largest threaded straight fitting in the resin/brass ladder. It joins Dia 12 mm soft nylon or polyurethane tube to a 1/2 in PT male thread. Push the tube home and the stainless spring gasket plus POM chuck grip it against the NBR O-ring; press the release ring and it slides straight back out. The body is brass with a brass stud, and the thread arrives with sealant pre-applied so no tape is needed on the port.
This is the resin/brass spec profile, not the metal BP line: 0-1.0 MPa working pressure (0-10 kgf/cm2), -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C. At Dia 12 it feeds the highest-capacity circuits the PC family supports, and capacity scales with the bore rather than any published flow number, which AirTAC gives only as a characteristic curve.

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 PC Threaded Straight Connector PC1204 Is Used
Punch press actuation line
Feeding the 12 mm line to a heavy pneumatic press cylinder, where the 1/2 in PT port on the valve manifold matches this fitting directly and the large bore supports fast cylinder cycling.
Air preparation drop
Taking the outlet of a filter-regulator-lubricator unit on a CNC machining cell down into 12 mm distribution tube, with the pre-sealed 1/2 in thread threading straight into the FRL port.
Packaging line main header
Hooking 12 mm branch tube onto the 1/2 in take-off points of a carton-sealer air header, where push-in assembly keeps changeover between station drops quick and tool-free.
Is the Airtac PC Threaded Straight Connector PC1204 the Right Part?
PC1204 sits at the very top of the PC threaded ladder: 1/2 in is the biggest thread and Dia 12 is the biggest tube that thread takes, so there is no step up from here. Stepping down on the same thread gives PC1004 (Dia 10, 1/2 in), which halves-down the bore for lighter circuits. Stepping down in thread instead gives PC1203 (Dia 12, 3/8 in), which keeps the full 12 mm bore where the port is smaller.
Match the thread to the port first, then the tube. The tubing must be exactly Dia 12 mm: 1/2 in nominal tube measures 12.7 mm OD and will not seal in a Dia 12 chuck, so do not mix the two conventions. If you need a right angle at the port rather than a straight run, the PL male elbow in the same 12 x 1/2 in combination is the shape to ask for.
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 PC Threaded Straight Connector PC1204 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and operating temperature -20 to +70 C. The fitting joins Dia 12 mm soft nylon or polyurethane tube to a 1/2 in PT male thread. It belongs to the resin/brass one-touch profile, so it is rated higher on pressure but lower on temperature than AirTAC's metal BP family.
No. A Dia 12 fitting grips tube that measures exactly 12.0 mm OD, while nominal 1/2 in tube measures 12.7 mm OD and will neither seat in the chuck nor seal on the O-ring. Use genuine 12 mm soft nylon or polyurethane tube. If your circuit is specified in inch sizes, AirTAC's separate N-series imperial fittings are the correct range instead.
