About the Airtac PL L Connector PL4M3-M
The AirTAC PL4M3-M is a mini-series one-touch male elbow from the PL family. It joins Dia 4 mm soft nylon or polyurethane tubing to an M3 male thread, the finest port size in this catalogue. Push the tube home and the POM chuck grips it against the stainless spring gasket; press the release ring to free it again. Because the body is an elbow, you can rotate the outlet to square up with the port before tightening the stud, which is what makes it the natural choice where a straight connector would foul the machine wall.
This is the resin and brass one-touch profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. Grey is the standard body colour; on PL series the D suffix changes the body to black as well as the release button, unlike on PC and POC where only the button changes.

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 PL4M3-M Is Used
Miniature pilot valve hook-up
Feed a Dia 4 mm polyurethane line from the fine-pitch outlet of a compact pilot valve on a small packaging machine, with the elbow turning the run 90 degrees back toward the frame.
Benchtop laboratory clamping jig
Pilot a small clamping jig on a test bench: the M3 stud suits the miniature ports on lab manifold blocks where a 1/8 inch fitting physically will not fit.
Small-part pick-and-place cell
Carry actuation air to a tiny gripper on a desktop pick-and-place unit, where the elbow shape keeps the Dia 4 mm tube clear of the Z-axis travel envelope.
Is the Airtac PL L Connector PL4M3-M the Right Part?
Dia 4 mm is not the bottom of this ladder: the PL mini series also accepts Dia 3.2 mm tube, a size that exists only on PC and PL mini parts, and steps up to Dia 6 mm, where the standard (non-mini) PL range takes over. On the thread side, M3 is the smallest option; the next steps are M5 and then 1/8 inch. Pick this elbow over a straight PC connector when the run must turn 90 degrees at the port, for example into a component mounted flush against a plate. Tubing OD must match exactly - a Dia 4 mm chuck will not seal on 6 mm tube, so never mix sizes on a run.
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 PL4M3-M FAQ
It is a mini-series PL male elbow for Dia 4 mm tube with an M3 thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature range -20 to +70 C. Applicable tubing is soft nylon or polyurethane, and the part belongs to the PT-thread one-touch catalogue line.
The -M marks AirTAC's mini one-touch series, offered only on the PC and PL prefixes. Mini parts carry the fine M3 or M5 threads and, uniquely, a Dia 3.2 mm tube option. Pressure and temperature ratings are identical to the standard resin line, so you select by port size and tube bore, not by rating.
