About the Airtac PLL L-Type Extended Thread Connector PLL401D
The PLL401D is an AirTAC PLL extended male elbow from the resin one-touch range: a 90 degree swivel elbow with a longer male thread than the standard PL, joining Dia 4 mm soft nylon or polyurethane tubing to a 1/8 inch PT male port. Push the tube squarely into the chuck and the stainless spring gasket grips it for a pressure-tight joint; press the POM release ring and the tube frees off again for rework.
This is the black -D version, and on PLL the D suffix changes the whole body, not just the release button as it does on PC and POC. It runs on the resin spec profile: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. Body and threaded parts are PBT on a brass stud, and the 1/8 inch thread arrives with sealant already applied so no extra tape or dope is needed.

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 PLL401D Is Used
Solenoid valve exhaust and pilot ports
A 1/8 inch PT port is the standard exhaust or pilot connection on compact 5/2 and 3/2 valves in small packaging machines; the PLL401D turns the 4 mm drop line down and away from the coil without kinking.
Miniature gripper supply on pick-and-place heads
Small pneumatic grippers and vacuum ejector assemblies on robot end-effectors draw from 4 mm lines; the extended male thread gives clearance for the swivel nut beside adjacent fittings on a dense manifold.
Tight guards on laboratory and test rigs
Where a control panel wall sits close to the cylinder, the long-reach elbow lets a 4 mm nylon line clear the guard lip and route vertically without fouling the port boss.
Is the Airtac PLL L-Type Extended Thread Connector PLL401D the Right Part?
Dia 4 is the smallest tube size the PLL ladder offers - the 3.2 mm option exists only on the PC and PL mini series, so there is no size down here. Step up to PLL601 for a 6 mm line feeding slightly larger pilot or signal circuits. On the thread side, the 1/8 inch is the smallest port; PLL402 keeps the same 4 mm tube but suits a 1/4 inch PT port. Choose PL if you need a shorter thread reach, or PLM if you must pass the fitting through a panel wall with a locknut (M12x1 for Dia 4). Tube OD must match exactly: a Dia 4 socket will not seal on 5/32 or 1/4 inch tube.
Match the 1/8 inch PT thread to the port before ordering - most compact valve and cylinder ports in this size class are 1/8, but check the port drawing rather than assuming.
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 PLL401D FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. It joins Dia 4 mm soft nylon or polyurethane tube to a 1/8 inch PT male thread with a swivelling elbow body in black PBT on a brass stud, with sealant pre-applied to the thread. Rated capacity is tied to the 4 mm bore; AirTAC publishes flow as a characteristic curve only, so use the curve for your circuit sizing.
No. One-touch chucks grip a single outside diameter, so the tube must be exactly Dia 4 mm soft nylon or polyurethane - a 5/32 inch (4.0 mm nominal) or 1/4 inch tube will not seat on the gasket. For other lines, order the matching PLL size: PLL601 for 6 mm tube on the same 1/8 port, or PLL402 for 4 mm tube into a 1/4 inch port. Note also that larger PLL threads narrow the tube choice: the 1/2 inch elbow starts only at Dia 10.
