About the Airtac PLL L-Type Extended Thread Connector PLL603-S
The AirTAC PLL603-S is an extended male elbow in the one-touch fitting family. It joins Dia 6 mm soft nylon or polyurethane tube to a 3/8 inch PT male thread, turning the line 90 degrees with a longer thread shank than the standard PL elbow so there is extra metal to seat against and room to get a wrench on. To connect, push the tube straight into the chuck until it stops; the internal grip locks it, and pressing the release ring frees it again.
The -S suffix makes this the SUS304 variant. On the PLL family that means the male stud is stainless steel 304 while the body stays PBT, so the thread that screws into your port is the part that resists corrosion. Pressure figures are unchanged from the standard resin line: 0 to 1.0 MPa working, 1.5 MPa proof, -750 mmHg vacuum, and -20 to +70 C. The thread arrives pre-coated with sealant, so no extra tape is needed on the port.

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 PLL603-S Is Used
Food-line cylinder behind a guard
A 90 degree drop from a packaging machine's lift cylinder port where daily caustic washdown would pit a brass stud. The SUS304 shank holds its thread through the rinse cycle while the PBT body shrugs off splash.
Electroplating jig lift circuit
Acid mist in a plating shop attacks threaded brass at the port first. Here the exposed male thread is stainless 304, so the elbow seating in the jig-lift cylinder survives where an uncoated stud would corrode and weep.
Tight guard elbow on a rotary indexer
When the cylinder port sits close to a machine wall, a straight connector cannot be wrench-tightened. The PLL's extended shank gives the spanner clearance, and the elbow points the Dia 6 tube down along the frame without a sharp sideways load.
Is the Airtac PLL L-Type Extended Thread Connector PLL603-S the Right Part?
On the 3/8 inch thread, Dia 6 is the smallest tube AirTAC makes in the PLL elbow - there is nothing below Dia 6 on this thread, so step down to a 1/4 inch port if you need Dia 4 tube. The next size up on 3/8 inch is Dia 8, which gives you a larger bore for shorter runs at the same circuit pressure. Note that a 1/2 inch PLL never takes a Dia 6 tube: that thread starts at Dia 10, so this SKU is your largest option if the port is 3/8 inch.
Match the thread to the component port, not to the tube, and remember the tube OD must match exactly - a Dia 6 one-touch chuck will not grip 1/4 inch (6.35 mm) hydraulic-style tube. If you need to pass through a panel instead of threading into a port, the PMF bulkhead connector is the correct shape, not this elbow.
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 PLL603-S FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), proof pressure 1.5 MPa, vacuum to -750 mmHg, temperature -20 to +70 C. The fitting joins Dia 6 mm soft nylon or polyurethane tube to a 3/8 inch PT male thread with sealant pre-applied. It is the SUS304 variant, so the male stud is stainless steel 304 and the elbow body is PBT. Flow is published by AirTAC only as a characteristic curve tied to the Dia 6 bore.
No. On the elbow family the -S option changes the male stud to SUS304; the elbow body, release button and chuck remain the standard POM and PBT construction. The dimension tables are identical to the standard PLL603, and the pressure and temperature ratings are unchanged, so you can swap one for the other without redesigning the port or the bracket.
