About the Airtac PLL L-Type Extended Thread Connector PLL4M5D
The PLL4M5D is an AirTAC PLL extended male elbow in the resin one-touch range, joining Dia 4 mm soft nylon or polyurethane tube to an M5x0.8 male thread. The extended elbow body keeps the tube stub stood off from the port face, so the tube clears neighbouring fittings and panel edges that a standard PL elbow would crowd. The D suffix gives this size a black body rather than the standard grey.
To make the joint, push the tube straight home and the internal chuck grips it; press the POM release ring to let it go. It is rated 0-1.0 MPa (0-10 kgf/cm2), handles -750 mmHg (10 Torr) vacuum, carries a 1.5 MPa proof pressure and works from -20 to +70 C. The M5 port seals on a dedicated gasket, so unlike the larger PT threads in this catalogue it arrives without thread sealant.

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 PLL L-Type Extended Thread Connector PLL4M5D Is Used
Pick-and-place gripper plumbing
M5 ports on small pneumatic grippers and rotary actuators sit close to the tooling plate; the extended elbow keeps Dia 4 mm tubing clear of the mounting bolts while making a right-angle turn into the port.
Compact vacuum ejector hookup
Miniature ejectors and suction cups on electronics assembly heads take M5 vacuum ports. This elbow routes 4 mm polyurethane tube at 90 degrees in the -750 mmHg range the part is rated for.
Manifold-mounted valve outlet
Small valve manifolds pack M5 outlets at tight pitch. The extended standoff stops the tube pressing against the adjacent valve body, and the black body blends with dark manifold plates.
Is the Airtac PLL L-Type Extended Thread Connector PLL4M5D the Right Part?
This is the smallest tube and thread the PLL extended elbow is made in: Dia 4 with M5 has only one sibling on each ladder, never a step down. Step the tube up to PLL6M5 for Dia 6 mm when the circuit feeds a slightly larger actuator, or step the thread up to PLL401 for a 1/8 inch port on the same 4 mm tube. The interface table lists M5 only with Dia 4 and Dia 6, so any other pairing is not manufactured.
Match the thread to the port, not the tube: M5x0.8 is common on small cylinders, vacuum ejectors and compact valve manifolds. If you need a swivel or a straight run instead of a fixed 90 degree elbow, the PH universal elbow or PC straight connector cover those shapes. Remember the tube OD must match exactly - a Dia 4 one-touch chuck will not hold 4 mm nominal tube that is actually 5/32 inch.
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 PLL L-Type Extended Thread Connector PLL4M5D FAQ
It is an extended male elbow one-touch fitting joining Dia 4 mm tube to an M5x0.8 male thread (PT standard). Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. Suitable tube is soft nylon or polyurethane; the black D-suffix body is PBT with a brass stud, and the M5 thread seals with a gasket.
No. M5 sizes in this range are sealed by a dedicated gasket rather than sealant, so screwing the stud in with PTFE tape or paste can distort the seal or crack the small female port. Engage the M5 thread by hand and seat it gently. Sealant is only applied at the factory on the larger PT-threaded sizes such as 1/8 inch and up.
