About the Airtac PL L Connector PL401D-M
The PL401D-M is an AirTAC PL male elbow from the mini series, finished in black (the D suffix colours the body on this family, not just the button). It joins Dia 4 mm soft nylon or polyurethane tubing to a 1/8in PT male thread, turning the air path 90 degrees right at the port. The -M suffix marks it as a mini-series part: smaller body, smaller hex, and access to sizes the standard PL range does not offer.
This is the resin and brass one-touch profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. To make the joint, push the tube straight in until it bottoms; the stainless spring gasket and POM chuck grip the OD, and pressing the POM release ring frees it again. The 1/8in thread arrives with sealant applied, so no extra tape is needed on first assembly.

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 PL401D-M Is Used
Miniature pick-and-place grippers
Compact gripper cylinders on electronics assembly heads rarely leave room for a straight connector. The PL401D-M elbows a Dia 4 mm line down into a 1/8in port with a black body that disappears against dark machine frames.
Benchtop lab and analyzer manifolds
Small pneumatic circuits inside analytical instruments run on Dia 4 mm nylon tube. This elbow lands on 1/8in valve ports inside crowded enclosures where a straight fitting would foul the cover.
Jig and fixture clamping cells
Workholding clamps on machining jigs take their air from short Dia 4 mm drops. A 90 degree mini elbow at the clamp port keeps the hose inside the fixture footprint and clear of swarf paths.
Is the Airtac PL L Connector PL401D-M the Right Part?
On the tube side, the PL401D-M sits above the Dia 3.2 mm mini elbow (a size only the PC and PL mini families carry) and below the Dia 6 mm PL402. Stepping to 3.2 mm buys the tightest possible bend for micro actuators; stepping to 6 mm roughly doubles the bore area and cuts restriction on longer runs. The tube OD must match exactly - a Dia 4 chuck will not seal on 1/4in (6.35 mm) tube, so do not substitute.
On the thread side, 1/8in PT is the workhorse port on small cylinders, solenoid valves and mini manifolds. If your port is M5 or M3 (M3 exists only in this mini range), pick the matching mini PL code rather than forcing an adapter into the stack - every adapter adds height that the elbow is there to save.
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 PL401D-M FAQ
It is a Dia 4 mm tube by 1/8in PT male elbow in the resin and brass one-touch mini series. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it holds vacuum to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. Use soft nylon or polyurethane tubing sized exactly to Dia 4 mm.
No. The chuck and gasket are sized to one tube OD only, so the PL401D-M holds Dia 4 mm tubing exclusively. For 6 mm tube order the Dia 6 equivalent in the same PL mini elbow form, and for imperial 1/4in tube move to a fitting made for that OD - forcing the wrong size into a one-touch joint is the most common cause of leaks and blow-off.
