About the Airtac PL L Connector PL1203D-S
The PL1203D-S is AirTAC's PL male elbow in the large-bore black build with a SUS304 stud: a right-angle one-touch fitting that joins Dia 12 mm soft nylon or polyurethane tubing to a 3/8 in PT male thread. Push the tube straight home and the internal chuck grips it against a stainless spring gasket; press the release ring and the tube pulls free without tools. Dia 12 is the biggest tube the PL range takes on any thread, so this elbow feeds the highest-volume actuator circuits in the series.
The -S suffix changes one thing: the threaded stud becomes SUS304, while the elbow body stays PBT in the D-suffix black finish and the dimensions match the standard part exactly. Ratings are unchanged from the resin line - 0 to 1.0 MPa working, 1.5 MPa proof, -20 to +70 C, and -750 mmHg vacuum. The stud is where corrosion bites, because it is the half screwed into the port, so the stainless sits precisely where a wash-down or salt-laden atmosphere attacks. Like every PT-threaded part here, it arrives with sealant already applied to the thread.

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 PL1203D-S Is Used
Food-plant wash-down manifold
The SUS304 stud threads into a stainless manifold in a poultry-processing wash-down zone, shrugging off caustic cleaning foam while the elbow turns the Dia 12 main feed 90 degrees into the cylinder port.
Gripper on a die-casting robot
A large Dia 12 bore feeds the clamping cylinder at the end of arm; the elbow points the tubing away from die spray, and the stainless stud stands up to the coolant mist around the tooling plate.
Marine valve actuation panel
In salt-laden air on a dredger or workboat, the SUS304 thread into the actuator valve port resists pitting where a plain brass stud would corrode, while the one-touch elbow makes hose changes dockside-simple.
Is the Airtac PL L Connector PL1203D-S the Right Part?
On the PL 3/8 in ladder the tube sizes run Dia 6, 8, 10 and 12, so PL1203D-S is the top of this thread's range; stepping down to PL1003D-S gives you a slimmer elbow and a smaller bore for lighter cylinder feeds. On the thread side, PL1202D-S (1/4 in) and PL1204D-S (1/2 in) both exist and carry the same Dia 12 tube, so match the thread to the port on your manifold, not to the tubing. The tube OD must match exactly - the Dia 12 chuck will not seal on 1/2 in (12.7 mm) imperial hose. If the run needs to pass through a panel wall rather than turn a corner, the PMF bulkhead connector is the shape to choose instead.
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 PL1203D-S FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and operating temperature -20 to +70 C. This SKU is a male elbow taking Dia 12 mm soft nylon or polyurethane tubing into a 3/8 in PT male thread, with a SUS304 stud and a black PBT body. It is the resin-line spec, not the 0.9 MPa metal BPC line.
No. AirTAC keeps the ratings identical to the standard resin PL elbow: 0 to 1.0 MPa working and 1.5 MPa proof, -20 to +70 C. Only the threaded stud upgrades to SUS304 for corrosion resistance; the body remains PBT and the dimensions match the standard part, so existing drawings and drilled ports stay valid without change.
