About the Airtac PC Threaded Straight Connector PC1201-S
The PC1201-S is AirTAC's PC male connector in the SUS304 stainless-steel version: the body itself is machined from Stainless steel 304, and the whole part is copper-free, not just the shell. It joins a Dia 12 mm soft nylon or polyurethane tube to a 1/2in PT male port. Push the tube home and the stainless spring gasket and chuck grip it; press the POM release ring and the tube slides back out.
Ratings are identical to the standard PC line, so do not re-rate it for the stainless build: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, and -20 to +70 C. What you are paying for is corrosion resistance and copper-free wetted parts for washdown, marine and chemical-adjacent circuits. The release button and chuck stay POM, the guide is aluminium alloy, and the O-ring is NBR.

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 PC Threaded Straight Connector PC1201-S Is Used
Fish-processing washdown frame
Feeding a Dia 12 gripper cylinder on a salmon-line conveyor frame where brine and daily hose-down attack brass bodies; the SUS304 shell and copper-free internals shrug both off.
Electroplating line actuation
Driving a Dia 12 tube run to a lid-lift air cylinder over plating tanks, where copper ions in the air circuit would contaminate the bath chemistry.
Marine deck valve pilot supply
Piloting a ball-valve actuator on a workboat deck, plugged straight into the 1/2in PT port on the valve manifold without a threaded adapter.
Is the Airtac PC Threaded Straight Connector PC1201-S the Right Part?
Dia 12 is the top of the PC ladder, so there is no tube size above it - the only step down on the 1/2in thread is Dia 10, which sheds roughly a third of the bore and suits lighter-demand cylinders and manifolds. On threads, 1/2in is also the ceiling; the step down is 3/8in, which on the PC prefix still takes Dia 12 tube, so PC1203-S is the way to keep the bore and shrink the port. Tube OD must match exactly: a Dia 12 fitting will not seal on 1/2in (12.7 mm) imperial tube.
If the run needs an angle at the port rather than a straight shot, the PHF universal female elbow also carries a SUS304 stud variant, and for mounting through a panel wall the PM bulkhead connector family covers Dia 12 with an M22x1 locknut thread.
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 PC1201-S FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. It connects a Dia 12 mm soft nylon or polyurethane tube to a 1/2in PT male thread. The body is SUS304 stainless steel and the construction is copper-free; pressure ratings are the same as the standard PC line.
Yes. AirTAC ships every threaded part in this catalogue with sealant already applied to the male thread, so the 1/2in PT port seals on assembly with no additional PTFE tape. Sealing gaskets are only used on the small M5 sizes, which this connector is not. Note that PT is the only thread standard published for these fittings - there is no G or NPT ordering code to switch to.
