About the Airtac PLL L-Type Extended Thread Connector PLL1204D-S
The PLL1204D-S is an AirTAC PLL extended male elbow, the one-touch fitting that screws into a 1/2 inch PT port and turns the tube run through 90 degrees while holding the drop further out from the port face than a standard PL elbow. It accepts Dia 12 mm soft nylon or polyurethane tube: push the tube home and the chuck grips it against the stainless spring gasket, press the release ring to free it. The D in the code makes the whole PBT body black, not just the release button as on PC and POC.
This is the -S stainless variant. On PLL parts the body stays PBT and the threaded stud is SUS304, so the stainless sits exactly where the fitting meets the port, which is where corrosion attacks first. Ratings are unchanged from the standard resin line: 0-1.0 MPa working pressure, 1.5 MPa proof, -20 to +70 C, vacuum to -750 mmHg. The male thread arrives with sealant pre-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 PLL L-Type Extended Thread Connector PLL1204D-S Is Used
Bottling line rinse zone
Airing a rinse-gate cylinder on a bottle washer, where the fitting sits in the washdown splash zone and the SUS304 stud resists the pitting a brass stud would suffer at the port.
Electroplating tank actuation
Driving a lid or jig-lift cylinder beside a plating tank, where acid fumes attack exposed brass hardware first and the stainless stud is the part doing the sealing.
Marine hatch cylinder drop
Feeding a deck hatch actuator on a workboat, where salt-laden air condenses on port fittings and the extended body keeps the tube drop clear of the mounting face.
Is the Airtac PLL L-Type Extended Thread Connector PLL1204D-S the Right Part?
Dia 12 is the top of the PLL ladder on a 1/2 inch thread, so there is no size up from here; the only neighbour is PLL1004-S at Dia 10, which suits lighter 10 mm lines and lower carry-over loads. If the port is 3/8 inch, PLL1203-S keeps the same 12 mm tube on a smaller thread instead of reducing the bore. For a straight run use PC, for a bulkhead pass-through a PMF is the right shape, and if the extension is unnecessary the plain PL elbow is shorter. The chuck grips a 12.0 mm outside diameter only - it will not hold 12.7 mm imperial hose or any other OD.
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 PLL L-Type Extended Thread Connector PLL1204D-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. It takes Dia 12 mm soft nylon or polyurethane tube on a 1/2 inch PT male thread, black PBT body with a SUS304 stud.
No. On -S parts of the PLL family only the threaded stud is SUS304; the elbow body remains PBT, here in black. Pressure, temperature and dimensions are identical to the standard PLL1204D, so never re-rate a stainless part, and no other stainless grade is offered in this range.
