About the Airtac PC Threaded Straight Connector PC1202D-S
The PC1202D-S is the SUS304 stainless-steel version of AirTAC's PC male connector, built to push a Dia 12mm tube straight into a 1/4in PT male thread. On this stainless variant the connector body itself is stainless steel 304 and the whole part is copper-free, while the release button and chuck stay POM, the guide stays aluminium alloy, and the spring gasket and O-ring are stainless and NBR as on the standard line. Push the tube home and the internal chuck grips it; press the release ring and the tube frees.
Ratings are identical to the standard resin/brass PC line: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C with soft nylon or PU tubing. The D suffix on a PC straight connector changes only the release button to black, not the body - and on the -S version the body is stainless regardless. The PT thread arrives with sealant applied, ready to wind into the port.

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 PC1202D-S Is Used
Seafood processing washdown
Dia 12 main air drops on a fish-filleting or shellfish line sit in constant salt-water spray; the SUS304 body resists the corrosion that pits a brass PC1002 in the same position.
Electronics nitrogen distribution
Copper-free construction suits inert-gas and process air near PCB handling areas, where copper ions can catalyse contamination on sensitive assemblies.
Marine deck cylinder feed
A 12mm supply to hatch-cover or gangway actuators on a ship's deck survives salt-laden air far better in stainless, with the 1/4in PT thread sealing into the manifold elbow.
Is the Airtac PC Threaded Straight Connector PC1202D-S the Right Part?
Dia 12 is the top of the PC ladder on a 1/4in thread, so there is no larger tube to step up to on this interface - the only move down is PC1002(-S), which drops the bore to Dia 10 and suitably lowers the air capacity of the run. If you need more thread than 1/4in, note that the PC table also lists Dia 12 under 3/8in and 1/2in threads, so the same bore exists on bigger ports. Tube OD must match exactly: a Dia 12 chuck will not seal on 1/4in (6.35mm) imperial hose.
Choose the -S when the environment, not the pressure, is the problem - the stainless body and copper-free construction are the only reasons to pay for it. No figure changes between standard and stainless versions.
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 PC1202D-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. This SKU takes Dia 12mm soft nylon or PU tube on a 1/4in PT male thread. These figures are identical to the standard PC1202 - the -S changes materials, not performance.
No. 1/4in tube has a 6.35mm OD and will not be gripped or sealed by the Dia 12 chuck; match the tube OD exactly to 12mm. Also note the thread here is PT (with sealant pre-applied) - this catalogue does not list a G or NPT variant of the PC stainless connector.
