About the Airtac POC Round Thread Straight Connector POC1202D-S
The POC1202D-S is AirTAC's POC compact male connector in the SUS304 stainless variant. It joins Dia 12 mm soft nylon or polyurethane tube to a 1/4" PT male thread, using the shortest body in the POC range so it sits close to the port face. Installation is one-touch: push the tube fully home and the chuck grips it against the stainless spring gasket; press the release ring and the tube slides straight back out.
On the straight-connector families the -S suffix changes the body itself to stainless steel 304, and AirTAC states the complete part is copper-free - the release button and chuck stay POM, the guide is aluminium alloy and the O-ring is NBR. The D in the code means the release button is black, which on PC/POC is a button-colour change rather than a body change. Every rating is identical to the standard version: 0-1.0 MPa working pressure, 1.5 MPa proof, -20 to +70 C, and the stud arrives with thread sealant applied.

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 POC Round Thread Straight Connector POC1202D-S Is Used
Plating-line rinse manifold
Feeding spray nozzles on an electroplating rinse header, where copper-free plumbing prevents copper ions entering the bath and the stainless body shrugs off electrolyte mist.
Marine hatch actuator feed
A 1/4" PT port on a deck hatch cylinder in salt-laden air, with the 12 mm bore sized for the fast closing stroke and no painted brass body to bubble or stain.
Bottling hall wash-down drop
A drop line to a case-packer gripper in a bottling plant's caustic foam-wash zone, where the stainless body and black release button stay identifiable after repeated hose-downs.
Is the Airtac POC Round Thread Straight Connector POC1202D-S the Right Part?
This SKU sits at the top of the POC ladder on a 1/4" port: Dia 12 is the largest tube the compact body takes at this thread, so there is no step up within POC - the next size down, Dia 10 on the same 1/4" thread, suits lighter actuator lines where a smaller bore keeps air velocity acceptable. Match the port first (1/4" PT here) and the tube second: the collet holds exactly Dia 12 mm OD, so a 12.7 mm nominal tube will not seal.
Choose this over the full-length PC body when port clearance is tight but you still need a 12 mm bore; choose the PL elbow instead when the tube must turn 90 degrees off the port. Where corrosion is the driver but the bore is smaller, the Dia 6 to Dia 10 stainless POC variants share the same copper-free body.
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 POC Round Thread Straight Connector POC1202D-S FAQ
It is a POC compact one-touch male connector with a SUS304 stainless, copper-free body, taking Dia 12 mm soft nylon or polyurethane tube onto a 1/4" PT male thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. These figures are the same as the standard grey version - the stainless variant changes the material, not the rating.
No. On the PC and POC straight connectors the D suffix only changes the release button to black; the body material comes from the -S suffix, which here makes the whole body SUS304. That is also a handy visual cue on a mixed manifold: the black button marks the stainless, copper-free stations.
