About the Airtac PL L Connector PL4M3D-M
The PL4M3D-M is an AirTAC PL male elbow in the mini one-touch series, turning an M3 male thread through 90 degrees into a Dia 4 mm push-in socket for soft nylon or polyurethane tubing. The D suffix makes it the black version, and on the PL family that means the body colour changes too, not just the release button. The elbow form lets the tube leave the port sideways instead of straight out, which is exactly what a cramped cylinder nose or a densely packed manifold block needs.
Push the tube home and the internal chuck grips it against the stainless spring gasket; press the POM release button to free it again. This is the resin and brass spec profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a working temperature of -20 to +70 C. Inside sit a POM release button and chuck, an aluminium-alloy guide, the stainless spring gasket and an NBR O-ring, with PBT on the threaded part and a brass stud behind it. Note that the mini series exists only under the PC and PL prefixes, so this size ladder is deliberately small-port territory.

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 PL4M3D-M Is Used
Mini gripper lines on pick-and-place heads
Compact pneumatic grippers and micro cylinders on electronics assembly heads are often ported M3, and their ports point into neighbouring mechanics. The 90-degree elbow with Dia 4 tube keeps the supply line flat against the tool plate instead of fouling the Z-axis travel.
Pilot signalling on laboratory test rigs
Bench-top leak testers and dispensing rigs run thin Dia 4 pilot lines to small actuators. The one-touch socket lets technicians swap sensing-leg tubes by hand between test setups, and the -750 mmHg vacuum rating covers the suction side of those circuits.
Elbow at the cylinder port inside a tight guard
On packaging machine cam stations, the small cylinder port often sits inches from the guard wall. A straight mini connector would crimp the tube against the sheet; this elbow turns the Dia 4 line along the machine face and clears the cover.
Is the Airtac PL L Connector PL4M3D-M the Right Part?
The M3 thread is the smallest port thread in the mini ladder, so there is no step down; the next thread up is M5, which buys you a more common port on standard manifold blocks and valve subplates. On the tube side, Dia 4 has one smaller sibling: the 3.2 mm size, offered only on the PC and PL mini series, for hair-fine sensing and pilot lines. Step up to Dia 6 when the run feeds something that breathes harder than a small pilot circuit.
Match the M3 stud to ports that are actually tapped M3 - forcing a larger thread in damages both parts. If the fitting has to pass through a sheet-metal wall, the PLM bulkhead male elbow with its Dia 4 locknut (M12x1) is the right shape instead. And remember the golden rule of push-in fittings: tube OD must match exactly, so a Dia 4 socket will not hold 1/4 inch or 5/32 inch tube.
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 PL4M3D-M FAQ
Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it withstands vacuum to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the working temperature range is -20 to +70 C. This SKU joins Dia 4 mm soft nylon or polyurethane tube to an M3 male thread, in black, as part of the AirTAC mini series. It is the resin and brass profile, not the 0.9 MPa / 150 C metal line.
The PL4M3D-M screws straight into a threaded port and the tube exits at 90 degrees. The PLM bulkhead version is built to pass through a panel or machine wall: it carries a locknut that clamps the fitting to the sheet, and for Dia 4 tube that locknut thread is M12x1. Choose PL when the port is accessible, PLM when the connection has to be made through a barrier.
