About the Airtac PL L Connector PL4M5
The PL4M5 is an AirTAC PL male elbow, a 90-degree one-touch fitting that joins Dia 4 mm soft nylon or polyurethane tube to an M5x0.8 male thread. Push the tube home and the stainless spring gasket plus chuck clamp it against pressure; press the POM release ring and the tube frees for repositioning. The elbow shape turns the air line at a right angle at the port, so the tube runs along the machine face instead of sticking straight out.
This is the resin one-touch profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. Construction is a POM release button and chuck, PBT elbow body on a brass stud, aluminium-alloy guide and an NBR O-ring. One detail worth knowing before install: unlike the larger threaded sizes, which arrive with sealant on the thread, the M5 stud is sealed by a dedicated gasket, so do not wrap it in PTFE tape.

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 PL4M5 Is Used
Compact gripper on a pick-and-place head
Small parallel grippers and mini cylinders often carry an M5 side port buried between the body and the mounting bracket. The PL4M5 elbows the Dia 4 supply line down along the wrist, keeping the envelope inside the robot's guarded sweep.
Valve manifold outlet on a laboratory dispenser
Benchtop fluid and reagent dispensers use M5 valve ports and thin 4 mm tubing to keep dead volume low. This elbow routes the line back toward the enclosure wall immediately, so the door and wiring ducts stay clear.
Vacuum ejector supply on a small end effector
Miniature venturi ejectors with M5 air inlets are common on light pick heads. Feeding them with a Dia 4 elbow keeps the supply tube flat against the tool plate, protecting it from snagging during fast transfers.
Is the Airtac PL L Connector PL4M5 the Right Part?
On the M5 thread, PL is offered in exactly two tube sizes: Dia 4 and Dia 6. Dia 4 is the smallest in the ladder, so PL4M5 has no smaller sibling - the step up is PL6M5, which carries the same M5 port on a Dia 6 bore. If your tube is 6 mm, move there; nothing else changes but the grip bore. If your thread needs to grow instead, the Dia 4 elbow also exists as PL401 (1/8 in) and PL402 (1/4 in) for ports that are too coarse for a gasket-sealed M5.
Match the fitting to the port before the tube: M5 is the metric fine port found on small valves and compact actuators, and it takes no thread tape. If you need the outlet to clear a nearby wall or guard by a few extra millimetres, the PLL extended male elbow is the stretched version of this same part. And whichever you pick, tube OD must match exactly - a Dia 4 chuck will not seal on 1/4 in (6.35 mm) imperial 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 PL4M5 FAQ
PL4M5 is a PL male elbow one-touch fitting for Dia 4 mm tube with an M5x0.8 thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. Applicable tubing is soft nylon or polyurethane; the standard body colour is grey.
No. M5 sizes in this catalogue are sealed with a dedicated sealing gasket rather than applied sealant, so the PL4M5 should be fitted to the port as delivered - wrapping the fine M5x0.8 stud in PTFE tape can jam the thread and prevent the gasket from seating. Only the larger threaded sizes arrive with sealant pre-applied.
