About the Airtac PL L Connector PL1204D-S
The PL1204D-S is an AirTAC PL male elbow in the one-touch range, joining Dia 12 mm soft nylon or polyurethane tube to a 1/2in PT male thread. The 90 degree turn lets the tube run vertically off a horizontal port instead of bending the hose sideways against the fitting collar. To make the joint, push the tube straight home until it bottoms; the stainless spring gasket and chuck jaws clamp it for both pressure and vacuum, and pressing the release ring lets it slide back out for rework.
This is the resin/brass spec line, so it runs at 0 to 1.0 MPa working pressure with a 1.5 MPa proof rating and -20 to +70 C service. The -S suffix does not move any of those numbers: on the PL family the body stays PBT, and what changes is the male STUD, which is SUS304 stainless steel. The D suffix gives this part its black body. The 1/2in thread arrives with sealant already applied, so it seals on the PT port as delivered.

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 PL1204D-S Is Used
Cylinder supply in a tight guard
On a palletizer's gripper arm, a Dia 12 line feeding a large-bore cylinder can be angled straight down from the 1/2in PT port instead of sweeping a stiff hose across the guard swing path.
Washdown frame with a stainless port
Threaded into a stainless manifold on a fish-processing or meat-wash conveyor, the SUS304 stud resists rust in the port threads while the black PBT body shrugs off daily hose-down spray.
Plating-line pick-and-place air
Above a chrome or nickel plating tank, the elbow points the Dia 12 tube up and away from the tank rim, and the stainless stud survives the misty atmosphere that corrodes plain brass threads.
Is the Airtac PL L Connector PL1204D-S the Right Part?
Within the PL 1/2in ladder the steps are Dia 6, 8, 10 and 12, so PL1004-D-S is the only neighbour below this SKU and there is no larger tube above Dia 12 in this catalogue. Stepping from Dia 10 to Dia 12 roughly widens the bore for higher demand circuits such as large-bore cylinder supply. If your port is 3/8in rather than 1/2in, PL1203-D-S carries the same Dia 12 tube down to that thread. Bulkhead duty is a different part: the PLM male elbow passes through a panel wall, using an M22x1 locknut at this tube size. Whichever you pick, tube OD must match exactly - a Dia 12 fitting will not grip 10 mm tube.
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 PL1204D-S FAQ
It is a one-touch male elbow for Dia 12 mm tube with a 1/2in PT male thread. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum capability is -750 mmHg (10 Torr), proof pressure is 1.5 MPa and the temperature range is -20 to +70 C. The -S version keeps every one of these figures; only the male stud changes to SUS304.
Yes. The PL ladder supports Dia 12 on both the 3/8in and 1/2in threads, so the 3/8in equivalent is PL1203-D-S. Do not mix tube sizes: the chuck and gasket in a Dia 12 fitting are cut for 12 mm OD only, so 10 mm or soft-walled substitute tube will not seal under vacuum or pressure.
