About the Airtac PL L Connector PL401
The PL401 is an AirTAC PL male elbow, a 90 degree one-touch fitting that joins Dia 4 mm soft nylon or polyurethane tubing to a 1/8in PT tapered male port. Because the outlet turns the air path at a right angle, the fitting sits flush against a cylinder head or valve face instead of standing proud the way a straight PC connector does. To connect, push the tube firmly into the collet until it bottoms out; the POM chuck grips the tube wall against a stainless spring gasket and NBR O-ring, and pressing the release ring frees it again.
This part belongs to the resin and brass one-touch line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and an operating temperature of -20 to +70 C. The 1/8in thread arrives with sealant already applied, so no tape or paste is needed, and the grey body is standard with no colour suffix in the code.

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 PL401 Is Used
Compact pick-and-place grippers
Small pneumatic grippers and stopper cylinders often carry only a 1/8in port on a cramped face. The PL401 turns the Dia 4 supply line 90 degrees so it hugs the body instead of fouling the gripper jaw travel.
Benchtop lab and vacuum setups
Rated to -750 mmHg, the PL401 suits small ejector and sampling lines on laboratory rigs where Dia 4 PU tube drops from a manifold and needs to enter a horizontally threaded port.
Valve manifold exhaust routing
On a compact 1/8in exhaust or pilot port of a solenoid valve bank, the elbow points the Dia 4 vent or pilot line away from adjacent fittings, keeping each valve station clear for maintenance.
Is the Airtac PL L Connector PL401 the Right Part?
Dia 4 is the smallest tube size the PL elbow is made in, so there is nothing below it - the next step up is the PL601 for Dia 6 tubing, which opens a visibly larger bore and suits short runs feeding small cylinders or air guns. On the thread side you can step down to the PL4M5 (M5x0.8, Dia 4 or Dia 6 only, sealed by a gasket rather than sealant) or up to the PL402 for a 1/4in port, which accepts tube sizes all the way to Dia 12. Match the thread to the existing port rather than adapting with bushings; a taper thread with factory sealant is the cleaner seal. Also check orientation: if the elbow itself cannot reach, the PLL401 extended male elbow or the PH401 swivel elbow gives you a longer or fully angular reach. Tube OD must match exactly - a Dia 4 fitting will not grip 1/4in (6.35 mm) tube, and forcing it destroys the chuck.
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 PL401 FAQ
The PL401 connects Dia 4 mm soft nylon or polyurethane tube to a 1/8in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure is -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. The release button and chuck are POM, the guide is aluminium alloy, the spring gasket is stainless, and the O-ring is NBR. The thread comes with sealant pre-applied.
No. The chuck is sized for exactly 4 mm outside diameter tubing. Imperial 5/32in (about 4 mm) is close but not identical, and the grip or seal can fail on it - order an inch-series fitting for inch tube instead. Also note that for a Dia 4 locknut pass-through application the matching bulkhead size is M12x1, so plan panel holes accordingly.
