About the Airtac PC Threaded Straight Connector PC1202-S
The PC1202-S is the SUS304 version of the AirTAC PC male connector, one of the straight one-touch fittings in the AirTAC range. It joins Dia 12 mm soft nylon or polyurethane tube to a 1/4in PT male thread. To make the joint you push the tube straight into the chuck until it bottoms out; the stainless spring gasket and chuck grip the tube wall, and pressing the POM release ring lets the tube slide back out for rework.
On the PC series the -S suffix does more than change the stud: the connector body itself is machined from Stainless steel 304, and AirTAC states that all parts are copper-free. The release button and chuck stay POM, the guide is aluminium alloy and the O-ring is NBR. Ratings are identical to the standard PC1202 - 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C - so the stainless variant is bought for corrosion resistance and copper-free air, never for a higher rating.

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 PC1202-S Is Used
Bottling-line wash-down drops
On a brewery or bottling hall rinse section, caustic foam and hose-down water eat brass bodies. The SUS304 body of the PC1202-S shrugs this off while still feeding a Dia 12 cylinder at full 1.0 MPa line pressure.
Copper-free feed to a semiconductor wet bench
Trace copper in compressed air can spoil plating and etch chemistry. Because every part of this fitting is copper-free, it is a clean choice for air lines serving electronics wet-process benches that take a 12 mm supply tube.
Marine deck-actuator supply
Salt-laden air on a ship's hatch or winch actuator corrodes plated brass within months. Push a Dia 12 nylon line into this stainless connector at the 1/4in PT port and the joint survives the spray zone.
Is the Airtac PC Threaded Straight Connector PC1202-S the Right Part?
This is the top rung of the PC 1/4in thread ladder. Step down to PC1002 (Dia 10 on the same 1/4in thread) when the actuator or manifold port is drilled for a 10 mm line; there is nothing above Dia 12 anywhere in this one-touch catalogue, so if your machine takes a bigger bore you are outside the range. If the port itself is the constraint, the same Dia 12 tube is also made on a 3/8in thread (PC1203) or a 1/2in thread (PC1204). Thread sealant on the male PT thread does the sealing - tape the port correctly rather than over-tightening. And always match the tube outside diameter exactly: a Dia 12 chuck will neither grip 10 mm nor 1/2in hose.
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 PC1202-S FAQ
It is a SUS304 stainless one-touch male connector for Dia 12 mm soft nylon or polyurethane tube on a 1/4in PT male thread. Working pressure is 0 to 1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and the temperature range is -20 to +70 C. The -S changes the materials, not these figures.
No. The one-touch chuck is sized for Dia 12 mm outside diameter only; 10 mm tube will not seal and inch hose will not fit. For 10 mm tube on the same thread order PC1002, and remember the PC -S version is copper-free stainless across the body, unlike the elbow and tee stainless variants where only the stud is SUS304.
