About the Airtac PLL L-Type Extended Thread Connector PLL6M5D-S
The PLL6M5D-S is an AirTAC PLL extended male elbow, the long-stud version of the PL male elbow family. It joins Dia 6 mm soft nylon or polyurethane tubing to an M5x0.8 male port, turning the air path 90 degrees and standing the thread further off the body so there is room for a spanner and for the sealing gasket. The -D suffix gives the black body colour, and the -S suffix is the stainless variant: on the PL family that means the male stud is SUS304, while the body remains PBT and the release button stays POM. Connection is one-touch: push the tube fully home and the stainless spring gasket and chuck grip it; press the release ring and the tube frees.
This part belongs to the resin/brass one-touch profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg, proof pressure 1.5 MPa, operating temperature -20 to +70 C. One detail worth knowing before you install: unlike the larger PT threads in this catalogue, M5 sizes do not rely on pre-applied thread sealant - they seal through a dedicated M5 gasket face, so over-taping the stud can actually prevent a proper seal.

POM release button and chuck, aluminium-alloy guide, stainless spring gasket, NBR O-ring; body brass or PBT depending on the part. Stainless (-S): SUS304 in place of brass - a solid SUS304 body on the PC and POC straight connectors, and a PBT body with a SUS304 stud on the elbow, tee and branch shapes. Working pressure, proof pressure and temperature are unchanged from the standard version. AirTAC publishes flow as a characteristic curve rather than a single figure, so no L/min value is listed.

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 PLL6M5D-S Is Used
Analytical instrument manifold
Lab-scale gas and sample-line manifolds are commonly tapped M5 with very little metal around each port. The extended M5 stud of the PLL6M5D-S clears the boss so the gasket seats properly, and the 90 degree turn routes a 6 mm line along the chassis instead of across the display.
Gripper circuit on a pick-and-place head
A small parallel gripper fed by 6 mm polyurethane tube usually sits between guarding with almost no side access. An elbow at the port points the tube down the arm, and the SUS304 stud resists the corrosive cutting-mist atmosphere around CNC machining cells.
Vacuum ejector feed on an electronics assembly bench
Compact vacuum ejectors and PCB-handling chucks are rated to -750 mmHg, which sits inside this fitting's vacuum limit. The M5 elbow plugs straight into the ejector's side port and the 6 mm supply drops from a small solenoid valve block above the bench.
Is the Airtac PLL L-Type Extended Thread Connector PLL6M5D-S the Right Part?
Within the M5 ladder of the PLL series only two tube sizes exist, Dia 4 and Dia 6, so the PLL4M5-S is the only step down and Dia 6 is already the top of the M5 range. If you need Dia 8 mm tube you must change thread as well: the next rung up is the 1/8" family, giving the PLL801-S, while the PLL601-S keeps Dia 6 mm but swaps M5 for a 1/8" stud. Match the thread to the port, not the tube - a lot of small valves and manifolds are drilled M5 even when the circuit runs 6 mm line. Tube OD must match exactly: a Dia 6 one-touch chuck will not hold 1/4" (6.35 mm) tube, which is a different size despite looking close. Choose the PLL shape over a straight connector when the tube has to leave the port at right angles and the extended stud over a plain PL gives your wrench clearance on a shallow port.
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 PLL6M5D-S FAQ
It is an AirTAC PLL extended male elbow in the black (-D) resin/brass one-touch line with a SUS304 male stud. It connects Dia 6 mm soft nylon or polyurethane tube to an M5x0.8 male thread (PT standard, M5 sealed by gasket). Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg, proof pressure 1.5 MPa and operating temperature -20 to +70 C. Ratings are identical to the standard brass-stud PLL6M5D; only the stud material changes.
On the PLL family the -S option makes the male stud SUS304 and leaves the elbow body as PBT, so it is not a solid stainless fitting. The corrosion resistance you gain sits exactly at the threaded interface, where a plain brass stud would otherwise be exposed to wash-down splashes, condensation or plating-bath fumes. Pressure, vacuum, proof pressure, temperature and every dimension stay the same as the standard part, so you can swap it into an existing PLL6M5D position without redrawing anything.
