About the Airtac POC Round Thread Straight Connector POC1203D-S
The POC1203D-S is AirTAC's compact one-touch male connector in the SUS304 stainless-steel variant, joining Dia 12 mm soft nylon or polyurethane tube to a 3/8in PT male thread. Compared with the PC straight connector, the POC body is the shorter, more space-saving shape - useful when the fitting sits close to a wall, guard or manifold face. Push the tube home and the internal chuck grips it for a pressure-tight seal; press the release ring and the tube slides straight back out.
On this -S version the body itself is machined from Stainless steel 304 and AirTAC states the entire fitting is copper-free, which suits corrosive or wash-down environments and processes where copper contamination matters. The release button and chuck stay POM, the guide is aluminium alloy, the spring gasket is stainless and the O-ring is NBR. The D suffix here specifies the black release button only. Ratings are the standard resin-line figures: 0-1.0 MPa working pressure, 1.5 MPa proof, vacuum to -750 mmHg, and -20 to +70 C.

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 POC1203D-S Is Used
Food-line wash-down drops
Feeding Dia 12 mm actuators on a bottling or bakery conveyor that is hosed down each shift. The SUS304 body and copper-free construction resist caustic foam cleaning where a plated brass body would pit.
Plating and chemical bench air
Supplying pneumatic clamps beside acid baths and rinse tanks on an electroplating line, where zinc or nickel plating chemistries attack copper-bearing fittings quickly.
Marine deck equipment
Hooking 12 mm air lines into hatch-closer cylinders or deck winches on coastal vessels, where salt fog swells and seizes ordinary brass connector bodies season after season.
Is the Airtac POC Round Thread Straight Connector POC1203D-S the Right Part?
On the 3/8in thread, POC offers Dia 8, Dia 10 and Dia 12 tube, so this is the largest bore on that port - the step down is POC1003 for Dia 10 tube, and there is no Dia 14 or 16 in this catalogue. Stepping up on the thread side, Dia 12 tube is also made on a 1/2in PT port (POC1204) if your valve or manifold carries the bigger thread. Match the port you actually have; adapters add leak points.
Tube OD must match the fitting exactly. A Dia 12 mm connector will not grip 12.7 mm (1/2in imperial) tube even though the difference looks trivial - the chuck is sized to the tenth of a millimetre. Confirm your tubing is soft nylon or polyurethane; rigid materials will not seal on a one-touch chuck.
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 POC1203D-S FAQ
It is a compact SUS304 stainless one-touch male connector for Dia 12 mm tube on a 3/8in PT male thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum to -750 mmHg (10 Torr), temperature -20 to +70 C. Tubing must be soft nylon or polyurethane, and the whole fitting is stated by AirTAC to be copper-free. The D suffix denotes the black release button; ratings are identical to the standard version.
No. The chuck in a Dia 12 mm one-touch connector grips 12.0 mm outside diameter tube and nothing else. 1/2in imperial tube measures 12.7 mm and will not seat or seal, even though the difference is under a millimetre. If your run uses 1/2in tube you need a purpose-made imperial fitting; if your tube is genuinely 12 mm, this is the correct part.
