About the Airtac PL L Connector PL401-M
The PL401-M is an AirTAC PL male elbow from the mini one-touch range, turning a Dia 4 mm tube through 90 degrees into a 1/8in PT male thread. The -M suffix marks the mini body, scaled down for small-bore circuits where a standard elbow is simply too tall around the port. To make the joint you push the tubing straight in until it bottoms: the stainless spring gasket and chuck jaws clamp the tube wall, and the POM release ring frees it again when you press it in. Because the body turns on the thread axis, the elbow can be clocked to point the tubing exactly where it must run.
This is the resin and brass spec profile, not the metal line: working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum down to -750 mmHg (10 Torr) and a temperature window of -20 to +70 C. The elbow body is PBT with a brass stud, the release button and chuck are POM, the guide is aluminium alloy and the seal is an NBR O-ring. Threaded AirTAC fittings of this type arrive with sealant already applied to the thread, so no tape or paste is needed on assembly; M5 sizes instead use a sealing gasket, which does not apply to this 1/8in version.

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-M Is Used
Compact pick-and-place gripper
A 4mm line feeding a miniature pneumatic gripper on a robotic end-of-arm tooling set, where the elbow's short mini body clears adjacent sensors on a 1/8in cylinder port.
Lab automation reagent handling
Small-diameter soft nylon tubing routed to a micro dispense valve in a laboratory analyser, with the elbow's vacuum rating of -750 mmHg covering the suction side of the pump circuit.
Control cabinet drop to a solenoid valve
A 90-degree drop from cabinet tubing into the 1/8in inlet of a compact valve manifold, keeping the 4mm line flat against the plate instead of standing proud.
Is the Airtac PL L Connector PL401-M the Right Part?
You are at the bottom of the mini ladder here. The only tube size below Dia 4 in this family is Dia 3.2 mm, which AirTAC makes solely on the PC and PL mini series, so if your tubing measures 3.2 mm OD you must move to a 3.2 code rather than forcing it. Stepping up one size gives the PL601 mini, still on a 1/8in thread, which buys a larger bore and lower resistance at the cost of a bulkier body. Whatever you choose, the tube OD must match the fitting exactly: a Dia 4 chuck will not seal on 1/4in or 5/32in tube, and no metric-imperial cross-fit exists in this catalogue.
Check the port before ordering. A 1/8in PT stud suits small cylinders, compact valves and manifold ports; if your port is M5, the mini PL in M5 is the more common pairing on micro actuators. If you need to pass the thread through a panel wall instead of screwing into it, the bulkhead male elbow PLM takes over from the PL 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 PL L Connector PL401-M FAQ
It is a mini male elbow one-touch fitting for Dia 4 mm tube on a 1/8in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum capability -750 mmHg (10 Torr), and the operating temperature range is -20 to +70 C. Use soft nylon or polyurethane tube, grey as standard. It is a resin and brass part: PBT body, brass stud, POM release button and chuck, NBR seal.
No. The chuck and gasket are sized for one tube OD only, and on this model that is Dia 4 mm. For 6 mm tube on the same 1/8in thread order the PL601. There is no imperial-tube version in this metric catalogue, and a 1/4in or 5/32in tube will neither seal nor lock correctly if forced in.
