About the Airtac PL L Connector PL402D-S
The PL402D-S is an AirTAC PL series one-touch male elbow in the SUS304 variant, joining Dia 4 mm soft nylon or polyurethane tubing to a 1/4in PT male thread set at 90 degrees. Push the tube straight into the chuck and the stainless spring gasket plus NBR O-ring seal it on the OD; press the release ring and the tube frees again without tools.
As with every PL-family -S code, the stainless is in the STUD (SUS304), not the whole body: the elbow body stays PBT in black (the D suffix), with POM release button, aluminium-alloy guide and a stainless spring gasket. Ratings are unchanged from the standard resin line: 0-1.0 MPa working, 1.5 MPa proof, -750 mmHg vacuum, -20 to +70 C. AirTAC ships 1/4in threads with sealant already on the thread.

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 PL402D-S Is Used
Cylinder port in a tight guard
Turning the Dia 4 pilot line 90 degrees off a compact guiding cylinder on a packaging machine, where a straight fitting would clash with the sheet-metal guard.
Valve manifold exhaust drop
Dropping a 4 mm signal line off the side port of a solenoid manifold on a small assembly station, with the 1/4in stud threading straight into the PT port.
Lab fixture actuation
Routing air to a small test-rig clamp where the black PBT body keeps the line tucked against the fixture plate and the SUS304 stud resists corrosive vapours.
Is the Airtac PL L Connector PL402D-S the Right Part?
On the 1/4in PT thread, Dia 4 is the smallest tube the PL ladder offers, so there is no smaller elbow on this thread to step down to; the next size up is the PL602 at Dia 6. If your port is 1/8in, the PL401 gives you the same Dia 4 tube on a shorter, lighter stud. Do not try to run other tube sizes in this body - a one-touch chuck only grips the exact OD it was made for.
Pick this shape when the air line must turn 90 degrees immediately at a port, for example on a cylinder nose or valve manifold where a straight connector would foul the machine wall. If you need a longer thread reach for a thick bracket, look at the PLL extended male elbow instead.
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 PL402D-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg, proof pressure 1.5 MPa, temperature -20 to +70 C. The fitting takes Dia 4 mm soft nylon or polyurethane tube on a 1/4in PT male thread. The stud is SUS304; the elbow body is black PBT. It is a one-touch push-to-connect part with a release ring.
AirTAC supplies 1/4in threaded parts with sealant already applied, so the stud can normally go straight into a PT port. (M5 sizes in this family use a sealing gasket instead - not relevant here.) The thread standard in this catalogue is PT only; there is no NPT or G ordering code, so match the port thread before ordering.
