About the Airtac PC Threaded Straight Connector PC1201D-S
The PC1201D-S is AirTAC's PC male one-touch connector in its SUS304 stainless version. It links Dia 12 mm soft nylon or polyurethane tubing to a 1/8" PT male thread. Push the tube into the chuck and the stainless spring gasket grips it for a pressure-tight joint; press the POM release ring and the tube slides straight back out.
Unlike the brass-bodied standard PC, this variant makes the body itself stainless steel 304, and AirTAC states the whole part is copper-free - a distinction that matters on the straight connectors, because on elbows and tees in the same family only the stud goes stainless. The ratings stay exactly those of the resin line: 0-1.0 MPa working, 1.5 MPa proof, -20 to +70 C, vacuum to -750 mmHg. The D suffix here changes only the release button to black, and the thread arrives with 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 PC Threaded Straight Connector PC1201D-S Is Used
Copper-free plating-line air drops
Above electroplating and chemical dosing tanks, copper-bearing brass fittings slowly corrode and contaminate the bath area. The copper-free SUS304 body on a 12 mm main feed removes that failure path at the 1/8" regulator or valve port.
Washdown conveyor cylinder supply
A food-line conveyor's pneumatic cylinder sits inside the nightly caustic wash. This stainless male connector plugs directly into the cylinder's 1/8" port and takes the Dia 12 feed line without a bracket, so the splash zone never sees bare brass.
Marine deck actuation panel
Salt-laden air eats plated brass within months on a ship's deck-mounted hatch actuators. A SUS304 body at the 1/8" port entry, feeding 12 mm nylon tubing to the actuator, keeps the connection serviceable through the vessel's life.
Is the Airtac PC Threaded Straight Connector PC1201D-S the Right Part?
On the 1/8" thread row of the PC ladder, Dia 12 is the largest tube offered - the step down is PC1001-S at Dia 10, which sheds bulk and suits smaller-bore air legs, but there is no Dia 14 or 16 above. If the circuit needs more bore on this fitting family, move the thread up instead: PC1202-S carries the same Dia 12 tube on a 1/4" PT port.
Match the 1/8" thread to the port you actually have - it seals on the applied sealant, so a taper port is assumed. And note the tube rule: the chuck is cut for 12 mm outside diameter only, so 1/2" imperial or 10 mm tube will not seat in this socket, no matter how hard it pushes in.
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 PC1201D-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. The part is a Dia 12 mm one-touch socket on a 1/8" PT male thread, with a SUS304 stainless body and copper-free construction. These figures are identical to the standard PC line - the stainless option changes materials, never ratings.
On the PC and POC straight connectors, the -S option turns the entire body into stainless steel 304, and AirTAC confirms all parts of the assembly are copper-free. On elbows, tees and crosses in the same family, the shaped body stays PBT and only the threaded stud becomes SUS304. If your process demands copper-free construction, the straight connector is the guaranteed form - always check the family before ordering a run.
