About the Airtac POC Round Thread Straight Connector POC1204D-S
The POC1204D-S is AirTAC's compact one-touch male connector in the SUS304 stainless version, joining Dia 12 mm soft nylon or polyurethane tubing to a 1/4in PT male thread. Push the tube home and the stainless spring gasket plus chuck grip it against the POM seal; press the release ring and it slides straight back out. The body itself is stainless steel 304, and AirTAC states every part in the assembly is copper-free.
This is the standard resin-line pressure profile, unchanged by the stainless build: 0 to 1.0 MPa working pressure, -750 mmHg vacuum capability, 1.5 MPa proof pressure and a -20 to +70 C service window. The D suffix on a POC part changes only the release button to black; the body stays grey-toned stainless in either case. The PT thread arrives with sealant pre-applied, so it seals on the port without extra tape on first assembly.

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 POC1204D-S Is Used
Pick-and-place on copper-free electronics lines
Feeding a Dia 12 vacuum-blowoff or gripper circuit above a PCB test bench, where the copper-free SUS304 body prevents copper particles reaching the clean process area.
Wash-down actuation in fish and meat processing
Driving a Dia 12 cylinder on a brine-washed conveyor gate, with the 304 stainless body and 1/4in PT sealed thread shrugging off salt-laden spray the brass body cannot.
Deck-mounted air on workboats
Supplying a hatch-clamp actuator from the ship's air main, where the POC1204D-S's compact stainless body resists the salt atmosphere that corrodes plated brass within a season.
Is the Airtac POC Round Thread Straight Connector POC1204D-S the Right Part?
On the 1/4in PT row of the POC ladder, Dia 12 is the largest tube offered, so the only step down is POC1004-S at Dia 10 - that drops the bore and the flow path area, which matters on long runs or short, fat cylinders that refill fast. If your port allows it, the same Dia 12 tube also fits the 3/8in POC1203-S and the 1/2in POC1204-S, both of which give a stiffer thread for high-vibration mounts. Tubing OD must match the fitting exactly: a Dia 12 chuck will not seal on 1/2in imperial tube. If you need to pass this connection through a panel or bulkhead, the PMF female bulkhead is the shape built for that instead of a straight connector.
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 POC1204D-S FAQ
Working pressure 0 to 1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. It joins Dia 12 mm soft nylon or polyurethane tube to a 1/4in PT male thread, and is the SUS304 stainless build with a black release button. Ratings are identical to the standard POC1204D.
No. The one-touch mechanism is unchanged: the same POM chuck and stainless spring gasket grip the tube, and the release ring frees it. What changes is the body material - on PC and POC straight connectors the whole body becomes SUS304 and the assembly is copper-free. The guide stays aluminium alloy and the O-ring stays NBR, so for fluids hostile to those elastomers, check compatibility before ordering.
