About the Airtac PLL L-Type Extended Thread Connector PLL603D
The PLL603D is an AirTAC PLL extended male elbow in the resin one-touch range, joining Dia 6 mm soft nylon or polyurethane tubing to a 3/8 inch PT male thread. The extended male elbow shape carries a longer threaded stud than the standard PL, so there is extra engagement length for sealing tape or pre-applied sealant on deeper ports. This D-suffix version arrives with the body moulded in black instead of grey, which suits panels and frames where a grey fitting would stand out.
The one-touch joint works by pushing the tube straight into the chuck: a POM release button and chuck clamp the tube against a stainless spring gasket and NBR O-ring, and pressing the release ring frees it again. The 3/8 inch thread comes pre-coated with sealant, so it can be screwed into a PT port without extra tape. Rated 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. The body is PBT with a brass stud.

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 PLL603D Is Used
Carton-closing cylinder under a guard
A swing cylinder on a carton sealer often sits recessed inside the machine frame. The extended stud of the PLL603D reaches past the frame wall so the 3/8 inch PT thread seals fully while the elbow turns the Dia 6 line upward along the guard.
Control cabinet air take-off
Feeding a Dia 6 line from a 3/8 inch manifold drop inside an electrical cabinet keeps the hose run tight to the panel wall. The black D body blends with painted enclosures instead of reading as an add-on.
Rotary indexer air feed
Indexing tables leave little clearance above the port face once the table is mounted. An extended male elbow angles the Dia 6 tube sideways, and the long stud keeps the sealant-coated 3/8 inch thread engaged even through a thick mounting plate.
Is the Airtac PLL L-Type Extended Thread Connector PLL603D the Right Part?
On the 3/8 inch ladder for PLL, Dia 6 is the smallest tube offered - the ladder runs 6, 8, 10, 12 - so there is no smaller step on this thread; the next size up is PLL803, which adds bore for circuits where a single 3/8 inch feed serves several actuators. If your port is 1/4 inch instead, PLL602 keeps the same Dia 6 tube on a smaller thread. Whatever you choose, the tube OD must match the fitting exactly: a Dia 6 chuck will not grip 1/4 inch tubing reliably.
Pick PLL over PL when the port sits inside a recess, behind a manifold face or under a shroud, because the extended stud lets the sealant-coated threads seat fully before the elbow body clears the obstruction. For a straight run at the same port, use PC603 instead; for a female-threaded elbow, PLF is the corresponding shape.
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 PLL603D FAQ
It is an AirTAC PLL extended male elbow one-touch fitting for Dia 6 mm tubing with a 3/8 inch PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and the operating temperature range is -20 to +70 C. It suits soft nylon or polyurethane tube, and the D suffix means the body is moulded in black.
No. AirTAC supplies the threaded stud of this fitting with sealant already applied to the 3/8 inch PT taper, so it can be screwed straight into a matching PT port. Use only soft nylon or polyurethane tubing of exactly 6 mm OD, push it fully home until it bottoms in the chuck, and grip the release ring to free it later. At high ambient heat, remember the tube itself is usually the limiting component, not the fitting.
