About the Airtac PLL L-Type Extended Thread Connector PLL801-S
The PLL801-S is AirTAC's extended male elbow one-touch fitting, the long-shank version of the PL male elbow. It joins Dia 8 mm soft nylon or polyurethane tube to a 1/8in PT male thread, and the extended shank puts the elbow further out from the port face so a right-angle turn can be made where a standard PL would foul the surrounding hardware. Connection is one-touch: push the tube squarely home and the internal chuck grips it under the stainless spring gasket; press the POM release ring and the tube frees. Threads arrive pre-coated with sealant, so no extra tape is needed on the 1/8in PT stud.
This is the -S SUS304 variant of the PL family, and the change is specific: the stud that screws into the port is stainless steel 304, while the elbow body itself remains PBT. Never describe this part as a solid stainless body. All ratings are identical to the standard PLL801 - working pressure 0-1.0 MPa, negative pressure -750 mmHg, proof pressure 1.5 MPa, temperature -20 to +70 C - so the stainless stud buys corrosion resistance on the wetted thread, not a higher rating.

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 PLL801-S Is Used
Rotary indexing table actuator port
On a rotary actuator tucked behind a machine guard, the extended shank lifts the elbow clear of the housing boss so the Dia 8 tube can drop vertically without kinking against the port face.
Plating line humid-air take-off
The SUS304 stud resists corrosion where chemical mist or constant condensation would pit a plain brass thread, making the 1/8in connection a sound choice on rinse and blow-off points in plating and wash plants.
Valve manifold side-port routing
Screwed into a side port of a solenoid valve manifold, the long shank angles the Dia 8 line down and away from adjacent cable looms, keeping tube runs off moving harness sections in a robotic pick-and-place cell.
Is the Airtac PLL L-Type Extended Thread Connector PLL801-S the Right Part?
On the tube side, Dia 8 sits between PLL601 (Dia 6, 1/8in) and PLL1001 (Dia 10, 1/8in); stepping up to Dia 10 moves more air per unit of tube length for longer runs, while Dia 6 suits compact actuators with lighter demand. On the thread side, PLL in 1/8in spans Dia 4 to Dia 10, and the next thread up is 1/4in (PLL802) - useful when the port is a larger cavity or the existing sealant seat is 1/4in. Note that M5 exists on PLL only for Dia 4 and Dia 6 tube, so an M5 version of this exact size is not offered.
Choose the extended elbow over the standard PL when the shank must clear a boss, guard plate or adjacent valve body before turning 90 degrees. Remember the tube OD must match exactly: a Dia 8 one-touch chuck will not grip 5/16in (8 mm nominal is fine, but 1/4in or 10 mm tube will not seal).
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 PLL801-S FAQ
This is an extended male elbow one-touch fitting with a Dia 8 mm tube connection and a 1/8in PT male thread, fitted with a SUS304 stainless stud on a PBT body. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure is -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. It accepts soft nylon or polyurethane tube of exactly 8 mm OD.
No. AirTAC rates the stainless -S variant of the PL family identically to the standard part: 0-1.0 MPa working, 1.5 MPa proof, -750 mmHg vacuum and -20 to +70 C. The stainless stud adds corrosion resistance on the threaded interface; it does not raise any rating, and the PBT body material is unchanged from the standard PLL801.
