About the Airtac PL L Connector PL603-S
The PL603-S is AirTAC's PL series one-touch male elbow in the stainless -S variant, joining Dia 6 mm tube to a 3/8 PT male thread at a right angle. Push the tube home and the internal chuck grips it while the stainless spring gasket and NBR O-ring seal; press the POM release ring and the tube slides free again. On -S parts within the PL family the threaded stud is SUS304 while the elbow body remains PBT, so the wet, threaded port that winds into your machine gets the corrosion resistance. The 3/8 thread arrives pre-coated with sealant, ready to wind straight into a PT port.
Ratings are identical to the standard resin-line PL603, because -S changes the stud material and nothing else: 0 to 1.0 MPa working, 1.5 MPa proof, -750 mmHg (10 Torr) vacuum, -20 to +70 C, soft nylon or polyurethane tube. A 3/8 port on a 6 mm bore deliberately leaves the smallest restriction inside the tube rather than at the fitting, which is why this pairing is a fixture on fixed-port manifolds running short, low-loss branches.

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 PL603-S Is Used
Chemical dosing skid
The 3/8 PT outlet on a dosing valve takes the SUS304 stud of the PL603-S, while the 6 mm polyurethane line turns 90 degrees toward the injection point without kinking - and the pre-applied thread sealant saves a PTFE wrap on a wet port.
Cartoning machine guard
An elbow at the blank-push cylinder port tucks the 6 mm line tight against the guard wall where a straight connector would foul. Service crews free the tube with the release ring without unwinding the fitting from the port.
Electroplating jig lifter
Acid mist near plating tanks quickly pits plain brass studs, so the SUS304 stud takes the 3/8 PT manifold port feeding the jig-lifter cylinder, with a 6 mm nylon line running the last short leg at line pressure up to 1.0 MPa.
Is the Airtac PL L Connector PL603-S the Right Part?
On the 3/8 PT ladder for PL elbows, Dia 6 is the smallest tube AirTAC makes - the next step up is PL803, an 8 mm bore on the same thread, which carries more air through a wider tube but needs the matching 8 mm line throughout. If your port is 1/4 instead of 3/8, PL602 carries the same 6 mm tube on the smaller thread and is usually the tidier fit on compact valve manifolds. Need more stand-off behind the elbow? PLL extended male elbows do the same job with a longer reach, and PLM is the bulkhead version for panel walls. Whichever you pick, tube OD must match exactly: a Dia 6 chuck will not seal on 1/4 (6.35 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 PL603-S FAQ
It is a one-touch male elbow for Dia 6 mm tube on a 3/8 PT male thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. Tube must be soft nylon or polyurethane. The -S suffix gives you a SUS304 stud with the standard PBT elbow body; every pressure and temperature figure matches the non-stainless PL603 exactly.
No. On -S parts in the PL family only the threaded stud is SUS304; the elbow body stays PBT, with a POM release button, aluminium-alloy guide, stainless spring gasket and NBR O-ring. If you need a fitting whose entire body is stainless 304, the PC and POC straight connectors are the series that offer that in -S form. Do not re-rate the part either way: temperature and pressure limits are unchanged from the standard catalogue.
