About the Airtac PLL L-Type Extended Thread Connector PLL6M5-S
The PLL6M5-S is AirTAC's extended male elbow in the stainless-stud (-S) configuration: it screws an M5x0.8 male thread into a port and turns the air 90 degrees into a Dia 6 mm one-touch socket. The M5 interface seals with a captive gasket rather than thread sealant, so the small brass thread stays clean on instrument-class ports. The elbow is deliberately stretched between thread and chuck, giving the tube an exit point clear of the port boss.
On this -S variant the male STUD is SUS304 stainless steel while the elbow body remains PBT; the release button and chuck are POM, the guide is aluminium alloy, and the O-ring is NBR. Ratings are unchanged from the standard resin line: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, -20 to +70 C, on soft nylon or polyurethane tube. Push the tube home until it bottoms, the chuck jaws grip it, and the release ring frees it again with a press.

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 PLL6M5-S Is Used
Robot gripper ports
Small pneumatic grippers and pick-and-place heads on electronic assembly robots are commonly tapped M5. The extended elbow drops the 6 mm line straight down off the wrist without the tube fouling the gripper body or the harness clamp.
Miniature valve manifolds
Compact solenoid valve manifolds on small packaging machines often expose M5 outlet ports side by side. The SUS304 stud resists wash-down splash, and the extended neck keeps six neighbouring tube bends from colliding on a dense port row.
Analytical instrument air feeds
Purge and actuation air inside laboratory analysers and sample-handling stations runs on thin nylon tube from M5 instrument ports. The one-touch chuck allows a tube swap during servicing without heating or re-sealing the threaded joint.
Is the Airtac PLL L-Type Extended Thread Connector PLL6M5-S the Right Part?
On the PLL ladder, M5 supports exactly two tube sizes: Dia 4 and Dia 6. That makes PLL6M5-S the LARGEST tube M5 can carry - there is no PLL8M5. If your line is Dia 4, order PLL4M5-S; if you need more bore, stay on Dia 6 and step the thread to the 1/8" version PLL6-01-S, whose brass sealant-coated thread suits standard pneumatic ports. Never force a fit between sizes: a Dia 6 socket will not reliably grip 1/4" (approximately 6.35 mm) tube, so metric tube must match exactly.
Choose the extended PLL shape over the plain PL when the fitting must stand off from a crowded port face or when a sharp 90-degree bend right at the thread would exceed the tube's minimum bend radius. For a straight-in connection the PC or POC connector is lighter duty; for a port on the far side of a component, the PH universal elbow swivels instead of locking the angle.
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 PLL6M5-S FAQ
It is an AirTAC extended male elbow for Dia 6 mm soft nylon or polyurethane tube with an M5x0.8 male thread (sealed by gasket, PT thread standard). Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it holds vacuum to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. The male stud is SUS304 stainless; the elbow body is PBT.
No. On the PLL series the M5 thread is offered only with Dia 4 and Dia 6 tube, so PLL6M5-S is the largest M5 part made. For Dia 8, Dia 10 or Dia 12 tube you move up the thread ladder to 1/8", 1/4", 3/8" or 1/2" versions of the same elbow. If you only need to step the bore down, a PG different-diameter union handles that without changing the thread.
