About the Airtac PL L Connector PL801D-S
The PL801D-S is an AirTAC PL male elbow from the resin one-touch range: it turns a run of Dia 8 mm soft nylon or polyurethane tubing through 90 degrees into a 1/8 inch PT male port. Push the tube home and the stainless chuck grips it under the guide; press the POM release ring and the tube slides straight back out, so rework at the machine takes seconds.
This -S suffix marks the SUS304 variant, and the split matters: on PL elbows the body stays PBT (black here, from the D suffix) and it is the threaded STUD that becomes stainless steel 304, which is what sits inside the port where corrosion starts. Ratings are unchanged from the standard resin line: 0-1.0 MPa working, 1.5 MPa proof, -750 mmHg vacuum, -20 to +70 C. The thread arrives with sealant already 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 PL L Connector PL801D-S Is Used
Cartoning machine guard pocket
On a horizontal cartoner, the pick-and-place cylinder port sits in a tight sheet-metal guard pocket where a straight connector would foul the cover. The PL801D-S turns the Dia 8 vacuum tube down along the frame in one bend, and the SUS304 stud shrugs off the daily wipe-down with mild detergent.
Electroplating jig lift line
Plating-line lift cylinders run air through tubing routed above splash trays where electrolyte mist settles on every fitting. The stainless 304 stud inside the 1/8 inch port resists the attack that soon pits a plain brass stud, while the PBT body shrugs off the same atmosphere.
Bottling line rinse-water skid
Actuating a rinse-water diaphragm valve on a bottling skid means an air line dropping vertically into a low port against the skid wall. A Dia 8 elbow lands the tube flat against the panel, and the 1/8 inch pre-sealed thread screws straight into the standard pilot port.
Is the Airtac PL L Connector PL801D-S the Right Part?
Dia 8 sits mid-ladder for the PL series. Step down to Dia 6 (PL601-S) when the line feeds small actuators or pilot circuits and you want a slimmer bend; step up to Dia 10 (PL1001-S) when a longer cylinder stroke needs more bore to hold speed. On the thread side, 1/8 inch is the smallest port offered in Dia 8 for this series (M5 exists only in Dia 4 and 6), and the next step up is 1/4 inch, PL802-S, for larger valve manifolds.
Match the thread to the port specification, not to what fits by eye, and check the port depth so the pre-sealed stud is not bottomed out on debris. If the port faces along the tube run instead of across it, the PH universal elbow articulates and may suit better. Tube OD must match exactly: a Dia 8 fitting will not seal on 5/16 inch or 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 PL801D-S FAQ
It is an AirTAC PL male elbow one-touch fitting joining Dia 8 mm soft nylon or polyurethane tube to a 1/8 inch PT male thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. The SUS304 suffix makes the threaded stud stainless steel 304; the body is black PBT. Release button and chuck are POM, guide is aluminium alloy, spring gasket stainless, O-ring NBR.
No. On PL elbows the -S option replaces the threaded STUD with SUS304; the body stays PBT (black on the D colour code). Only the PC and POC straight connectors in the stainless line get a solid stainless 304 body. If you need the whole fitting in stainless, those are the series to look at, and no pressure or temperature figure changes either way.
