About the Airtac POC Round Thread Straight Connector POC1204-S
The POC1204-S is AirTAC's POC compact male connector in its SUS304 stainless form, joining Dia 12 mm soft nylon or polyurethane tubing to a 1/2in PT male port. Because this is a straight connector in the PC/POC family, the -S suffix makes the fitting body itself stainless steel 304 and copper-free - not just the stud as on elbow and tee shapes.
It works as a true one-touch fitting: push the tube home and the stainless spring gasket and chuck grip it under the full working pressure; press the POM release ring to free it again. Ratings are unchanged from the grey resin version: 0-1.0 MPa working, 1.5 MPa proof, -750 mmHg vacuum, -20 to +70 C. The dimension tables are identical too, so it drops straight into a design drawn around the standard POC1204.

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 POC1204-S Is Used
Wash-down food packaging line
A SUS304 body shrugs off daily caustic hose-down on a packaging machine's actuator supply, where a brass POC1204 would discolour and pit between shifts.
Electronics plating and wet-process tools
Copper-free construction matters on wet-bench and plating equipment, where dissolved copper from a brass fitting can contaminate the process bath or catalyse unwanted reactions.
Marine and coastal equipment
Salt-laden air attacks plated brass quickly; the stainless body on a boat lift or dockside air supply keeps the Dia 12 main line connected and serviceable for years.
Is the Airtac POC Round Thread Straight Connector POC1204-S the Right Part?
Within the POC 1/2in thread ladder there are only two tube sizes: Dia 10 and Dia 12. Step down to the POC1004-S for a 10 mm line; there is no Dia 16 in this catalogue, so the POC1204-S is the top of the range on this thread. If the port is 3/8in instead, the POC1203 keeps the same 12 mm bore on the smaller thread.
Match the 1/2in PT thread to the port before anything else - this catalogue documents PT only, and the male thread arrives with sealant pre-applied, so no extra tape is needed for a metal-to-metal port. One-touch chucks grip one OD only: a Dia 12 collet will not hold 1/2in imperial tube, so confirm the tubing is genuinely 12 mm OD before ordering.
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 POC1204-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2); vacuum to -750 mmHg (10 Torr); proof pressure 1.5 MPa; temperature -20 to +70 C. Size: Dia 12 mm tube OD into a 1/2in PT male thread. The body is stainless steel 304 and copper-free; the release button and chuck are POM, the guide is aluminium alloy, and the O-ring is NBR. These figures are identical to the standard grey POC1204 - the stainless variant is not re-rated.
No. Use the same soft nylon or polyurethane tube as the standard fitting, and remember the tube, not the fitting, sets the limit near the 70 C ceiling. The dimensions match the standard POC1204 exactly, so no panel or manifold change is required. AirTAC publishes no torque figure for the 1/2in thread - the factory sealant is designed to seal as installed, so avoid over-tightening into the port.
