About the Airtac PL L Connector PL1204-S
The PL1204-S is AirTAC's PL male elbow one-touch fitting in the stainless-stud variant, turning a Dia 12 mm tube through 90 degrees into a 1/2" PT male thread. Push the tubing home and the internal chuck grips it for a pressure-tight joint; press the POM release ring and the tube slides straight back out. No tools, no ferrules, no re-taping.
This is a resin-line part: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg, proof pressure 1.5 MPa, and a service window of -20 to +70 C with soft nylon or polyurethane tubing. Because it carries the -S suffix, the male stud is SUS304 stainless steel while the elbow body remains PBT - so the corrosion-exposed thread that screws into the port is the stainless element, not the whole shell. The 1/2" thread arrives with sealant already applied; just hand-start it and tighten.

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 PL L Connector PL1204-S Is Used
Large-bore cylinder drop on a pneumatic press
A 90-degree turn straight into the 1/2" PT port of a Dia 12 mm-fed press cylinder, keeping the supply line flat against the machine frame instead of looping it into the die area.
Splash-zone takeoff on a washdown conveyor line
Where caustic rinse reaches the pneumatic drop on a bottling or meat-processing conveyor, the SUS304 stud resists thread corrosion even though the PBT body handles the wet zone with its own chemistry resistance.
Actuator supply on marine deck equipment
Hatch-cover and gangway actuators exposed to salt air benefit from the stainless thread at the port interface, with the elbow letting the Dia 12 mm run hug the deck head.
Is the Airtac PL L Connector PL1204-S the Right Part?
Dia 12 is the top of the PL ladder, so the only step down on a 1/2" thread is the PL1004 (Dia 10 tube) - the flow path narrows with the bore, but the fitting is slimmer and the tubing is cheaper and easier to route. If your port is 3/8" instead of 1/2", the same 12 mm tube is served by the PL1203. Both neighbours sit on the PL row, which supports 1/2" in Dia 6, 8, 10 and 12.
Match the thread to the port on the actuator or manifold, not to the tube - the tube side is fixed at Dia 12 and will not accept 1/2" OD hose or any other size. If you need to pass through a panel or enclosure wall rather than elbow off a port, a PLM bulkhead male elbow with its M22x1 locknut is the correct shape, not this one.
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 PL L Connector PL1204-S FAQ
It is a PL male elbow one-touch fitting for Dia 12 mm tube with a 1/2" PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it handles vacuum down to -750 mmHg, proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C with soft nylon or polyurethane tubing. The -S suffix puts a SUS304 stud on the thread side; the elbow body is PBT.
No. On elbow and tee families like the PL series, AirTAC's -S option converts the male stud to SUS304 while the body stays PBT, and the published dimensions and pressure figures are identical to the standard grey part. Only the straight PC and POC connectors get a solid SUS304 body. So this part is best specified where the threaded interface faces the corrosive environment, not as a all-stainless component.
