About the Airtac PL L Connector PL1201D-S
The PL1201D-S is an AirTAC PL series one-touch male elbow that turns a Dia 12 mm tube through 90 degrees into a 1/8 inch PT male thread. To make the joint you simply push the tube into the chuck until it bottoms out - the stainless spring gasket and chuck teeth grip it along its full circumference - and the release ring lets it go again just as quickly. The D suffix gives this version a black body, and the trailing -S means the male stud is machined from SUS304 stainless steel rather than the standard brass.
This is the resin spec profile, so the ratings stay exactly as published for the standard PL line: 0 to 1.0 MPa working pressure (0 to 10 kgf/cm2), 1.5 MPa proof pressure, -750 mmHg (10 Torr) vacuum capability and a -20 to +70 C temperature window. The 1/8 inch thread arrives with sealant already applied, and the PBT body with SUS304 stud is the correct stainless configuration for this family - the straight PC and POC connectors get a full stainless body, the elbows get the stainless stud.

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 PL1201D-S Is Used
Cylinder port turn on a carton sealer
The 1/8 PT stud screws straight into the head of a double-acting cylinder on a carton-sealing machine while the Dia 12 line exits at 90 degrees, clearing the side cover instead of bending tightly against it.
Wash-down area of a food conveyor frame
On a bakery conveyor that gets hosed down at shift end, the SUS304 stud resists the corrosion a brass stud would show around the thread, while the PBT body shrugs off detergent splash.
Manifold branch to a clamp actuator
A valve manifold block drilled with 1/8 ports feeds a Dia 12 trunk line down to a clamping fixture, and the elbow sets the tube direction parallel to the manifold face so it clips into a channel cleanly.
Is the Airtac PL L Connector PL1201D-S the Right Part?
On the PL ladder a 1/8 inch thread carries tube from Dia 4 up to Dia 12, so this fitting is the largest tube you can hang off an 1/8 port. Step down to PL1001 for Dia 10 tube on the same thread, or keep Dia 12 and move to PL1202 if the port is 1/4 inch - the bore stays the same, only the mating thread grows. Choose the elbow over a straight PC connector whenever the run has to turn at the port and a 90 degree bend in the tube itself would flatten its profile or foul a guard.
Check two things before ordering. First, tube OD must match exactly: a Dia 12 chuck will not seal on 1/2 inch (12.7 mm) or any imperial tube, and soft nylon or polyurethane are the only tubing types covered by the ratings. Second, confirm the mating port is PT - AirTAC documents this catalogue in PT only, so there is no G or NPT variant of this code to fall back on.
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 PL1201D-S FAQ
It is a one-touch male elbow joining Dia 12 mm tube to a 1/8 inch PT male thread, with a black PBT body and a SUS304 stainless stud. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), proof pressure is 1.5 MPa, it tolerates -750 mmHg (10 Torr) vacuum, and the temperature range is -20 to +70 C. Applicable tubing is soft nylon or polyurethane. The stainless suffix changes no rating - these figures are identical to the standard PL1201D.
No. On the PL elbow family the -S option fits a SUS304 stainless male stud while the body and release button remain the standard construction (PBT and POM respectively). Only the straight PC and POC connectors receive a solid SUS304 body in the stainless catalogue. Pressure, vacuum and temperature ratings are unchanged, and no surface finish or certification figures are published for the stainless option, so size the part on corrosion resistance alone.
