About the Airtac PLL L-Type Extended Thread Connector PLL803-S
The PLL803-S is an AirTAC PLL extended male elbow from the one-touch fitting range, joining Dia 8 mm soft nylon or polyurethane tube to a 3/8 inch PT male thread. The elbow shape turns the tube 90 degrees off the port, and the extended male thread section stands the fitting further out from the mounting face than a standard PL, giving spanner access and keeping the tube clear of adjacent hardware.
This is the -S variant. On the PL family the stainless upgrade is applied to the STUD, which is SUS304, while the body stays PBT with the usual POM release button, aluminium-alloy guide, stainless spring gasket and NBR O-ring. Ratings are identical to the standard part: 0 to 1.0 MPa working, 1.5 MPa proof, -750 mmHg vacuum and -20 to +70 C. The 3/8 inch thread arrives with sealant already applied, so it seals on the PT taper without extra tape.

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 PLL803-S Is Used
Cylinder port on a guarded packaging machine
On a horizontal form-fill-seal machine, the cylinder ports often sit inches from the frame guard. The PLL803-S turns the Dia 8 line 90 degrees and its extended thread stands the elbow proud of the port so a spanner still fits during changeover.
Plating line air feed near corrosive wash
On an electroplating or pickling line, acid mist attacks brass hardware. The SUS304 stud on this -S version resists that attack where a plain PLL803 would tarnish, without changing any pressure or temperature figure.
Rinse-down zone beside a food conveyor
Where an air drop feeds a reject pusher next to a conveyor that is hosed down each shift, the stainless stud on the 3/8 inch thread shrugs off repeated caustic rinse, while the Dia 8 push-in keeps re-tubing fast.
Is the Airtac PLL L-Type Extended Thread Connector PLL803-S the Right Part?
On the PLL 3/8 inch row, the neighbouring sizes are Dia 6 below (PLL603) and Dia 10 above (PLL1003). Stepping down to Dia 6 shrinks the bore for lighter actuator circuits; stepping up to Dia 10 suits larger cylinders and higher-feel air demands, with the elbow body growing accordingly. Note that if you move to a 1/2 inch PLL thread, the catalogue only offers Dia 10 and Dia 12 tube - there is no 1/2 inch PLL in Dia 8.
Choose an extended male elbow over a straight PC connector whenever the port sits close to a wall, guard or neighbouring fitting and the tube needs to leave sideways. Tube OD must match exactly: a Dia 8 chuck will not reliably grip 5/16 inch or 10 mm tube, and forcing a mismatch is the most common cause of leaks on push-fit lines.
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 PLL803-S FAQ
It is a one-touch extended male elbow with a Dia 8 mm tube socket and a 3/8 inch PT male thread. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa and temperature range -20 to +70 C. It runs on soft nylon or polyurethane tube. The -S suffix means the male stud is SUS304; pressures and temperatures are unchanged from the standard PLL803.
No. On the PL elbow family, the -S option converts the male stud to SUS304 for corrosion resistance; the elbow body remains PBT with a POM release button and NBR O-ring. This is different from the straight PC and POC connectors, where -S makes the body itself stainless 304. If your application needs an all-stainless body, pair the PLL803-S with a PC8xx-S type connector rather than expecting the elbow to be solid stainless.
