About the Airtac PL L Connector PL601D-S
The PL601D-S is an AirTAC PL series one-touch male elbow in the stainless-stud variant. It joins Dia 6 mm soft nylon or polyurethane tubing at a right angle to a 1/8 in PT male thread. Push the tube into the chuck until it seats and the stainless spring gasket grips it; press the release ring to free it again. A detail worth knowing before you order: on the PL family the -S option upgrades the male STUD to SUS304 only - the elbow body stays glass-reinforced PBT, and the D suffix keeps that body black rather than the standard grey.
This part runs the resin spec profile, not the metal BPC line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg, proof pressure 1.5 MPa and a temperature window of -20 to +70 C. The 1/8 in PT thread arrives with sealant already applied, so no PTFE tape is needed at assembly. Choosing the SUS304 stud makes sense where condensate, plating vapours or recurring wash-down splash would pit a plain brass stud on the one part of the fitting that actually screws into your machine.

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 PL601D-S Is Used
Cylinder drop inside guarding
On a cartoning machine, the 90 degree body lets Dia 6 tube exit a double-acting cylinder port and run flat along the aluminium extrusion of the guard instead of fouling the moving tooling.
Plating and rinsing stations
Near electroplating tanks and rinse baths, acid fumes attack exposed brass. The SUS304 male stud on this elbow keeps the threaded connection to the fixture manifold sound between maintenance windows.
Solenoid manifold outlets
Feeding a single station off an 1/8 in PT manifold port, the elbow turns the airflow out of the valve face and lets Dia 6 nylon tubing drop vertically to a bench-mounted clamp actuator.
Is the Airtac PL L Connector PL601D-S the Right Part?
On the 1/8 in PT rung of the PL ladder, Dia 6 sits in the middle of five options: Dia 4, 6, 8, 10 and 12. Step down to the PL401-S when the line feeds a small gripper or reed-switch cylinder where a slimmer bore is enough; step up to the PL801-S to serve larger bore actuators with less restriction through the elbow. Before stepping up a thread instead, check the port: a 1/8 in fitting can be stepped to 1/4 in on this series, but the tube chuck always matches one OD exactly - a Dia 6 chuck will not clamp 1/4 in (6.35 mm) imperial tube, which is only 0.35 mm wider.
Shape matters as much as size. If the tube must leave the port further from the machine surface, the PLL extended elbow gives you that reach. If you need to pass through a sheet-metal wall or enclosure panel, that is a job for the PLM bulkhead elbow or PM bulkhead union, both of which use the same Dia 6 locknut pitch of M14x1.
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 PL601D-S FAQ
It is an AirTAC PL one-touch male elbow with a Dia 6 mm tube chuck and a 1/8 in PT male thread, -S version. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure goes to -750 mmHg, proof pressure is 1.5 MPa and the operating temperature range is -20 to +70 C. These figures are identical to the standard PL601 - the -S suffix changes the male stud material to SUS304 and nothing else, so the part must never be re-rated on a stainless page.
No. AirTAC ships every threaded part in this catalogue with sealant already applied to the PT thread, so the PL601D-S screws straight into a 1/8 in port. AirTAC publishes no tightening torque for these fittings, so assemble to a sealed joint without levering on the PBT elbow body. If you later find the connection weeping after dismantling, renew the sealant rather than stacking tape over the old coating.
