About the Airtac PLL L-Type Extended Thread Connector PLL1003
The PLL1003 is an AirTAC PLL extended male elbow, a 90-degree one-touch fitting with a longer male thread nose than the standard PL. It connects Dia 10 mm soft nylon or polyurethane tube to a 3/8 inch PT thread. You push the tube straight into the chuck until it bottoms out; the stainless spring gasket and chuck grip the tube wall, and pressing the POM release ring lets the tube spin freely and pull out for rework. This is the resin and brass profile, not the metal BP line: working pressure 0-1.0 MPa, vacuum down to -750 mmHg, proof pressure 1.5 MPa, and a service temperature of -20 to +70 C.
The extended nose is the reason to choose PLL over PL: the extra reach keeps the release ring clear of shrouds, valve manifolds and recessed cylinder ports, so fingers and release tools fit where a compact elbow would bury itself. The 3/8 inch thread arrives with sealant pre-applied, so it seals on PT tapered ports without extra tape. The body is PBT with a brass stud, and the grey body is the standard finish on this series.

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 PLL1003 Is Used
Rear port on a pneumatic cylinder
Mount the PLL1003 on the rear port of a 40 mm bore cylinder on a packaging machine, where the shroud leaves just enough room for the extended nose and a fingertip on the release ring.
Valve manifold outlet
Use the elbow to turn a 3/8 inch manifold outlet 90 degrees on a control valve bank, sending a Dia 10 line down along the frame instead of out toward the guard.
Conveyor stop gate actuator
Feed a compact rotary or linear gate actuator on a bottling conveyor with a Dia 10 drop line, using the elbow to hug the actuator body and clear the guarding rail.
Is the Airtac PLL L-Type Extended Thread Connector PLL1003 the Right Part?
On the PLL ladder at 3/8 inch thread you can step down to the PLL803 (Dia 8 tube) for lighter lines feeding small actuators, or up to the PLL1203 (Dia 12 tube) when the same port must feed a higher-volume cylinder; the bore, not the thread, sets what the line can carry. Note the ladder rules: a 1/2 inch PLL only exists in Dia 10 and Dia 12 tube, so staying at 3/8 inch keeps you the widest tube choice at this size class. If the port sits behind a panel wall, the PLM bulkhead male elbow in Dia 10 uses an M20x1 locknut instead - a different answer for a different wall thickness.
Match the 3/8 inch PT thread to the port drawing; do not force it into a 1/4 inch boss because the shoulder can bottom before the sealant bites. And respect the one-touch rule: the fitting takes Dia 10 mm tube only, never 3/8 inch inch-sized hose, which runs oversize and will not seal.
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 PLL1003 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg, proof pressure 1.5 MPa, temperature -20 to +70 C. It connects Dia 10 mm soft nylon or polyurethane tube to a 3/8 inch PT thread. The body is PBT with a brass stud, the release button is POM, the guide is aluminium alloy and the O-ring is NBR. This is the resin and brass profile, not the 0.9 MPa / 150 C metal BP line.
The PLL carries the thread on a longer stud, so the release ring stands proud of the port even on recessed or manifold-mounted positions where a compact PL would hide the button under the shoulder. Both take the same tube sizes and the same 0-1.0 MPa rating; the extension changes access and wrench clearance, not performance. If you need the thread to pass through a panel, step to the PLM bulkhead male elbow instead.
