About the Airtac PLL L-Type Extended Thread Connector PLL4M5D-S
The PLL4M5D-S is an AirTAC PLL extended male elbow, the stainless-stud version of the elongated push-in elbow, in black. It joins Dia 4 mm soft nylon or polyurethane tubing to an M5x0.8 male port, and the -S suffix upgrades the threaded male stud to SUS304 stainless steel while the elbow body itself remains PBT. Because it is a resin/brass one-touch part, it carries the standard resin-line ratings: 0-1.0 MPa working pressure, -20 to +70 C.
Fitment is the usual one-touch action: push the tube in and the stainless spring gasket and chuck clamp it against the NBR O-ring seal; press the POM release ring to free it. What separates PLL from a plain PL elbow is the longer threaded neck. That extension lifts the elbow clear of the mounting face, so a spanner reaches the flats and the release ring stays accessible even when the port sits between other components. Note that M5 ports do not take thread sealant: the seal is made by a soft sealing gasket under the shoulder of the fitting, so over-tightening buys nothing and can crush the gasket.

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 PLL4M5D-S Is Used
M5-ported valve manifold on a pick-and-place head
Compact directional valves on small pick-and-place units often carry M5 ports spaced a few millimetres apart. The extended neck of the PLL4M5D-S clears the neighbouring valve body so the spanner fits and the release ring stays pressable, while Dia 4 PU tubing routes down to the suction or gripper line.
Sample lines inside a laboratory analyser
Benchtop analysis and dosing instruments run short Dia 4 soft-nylon jumps between an M5 manifold port and a reagent pump. The SUS304 stud resists corrosion from incidental condensation and cleaning fluids in the enclosure, and the black PBT body does not stand out against dark internal panels.
Compact gripper changeover on a packaging machine
Small parallel grippers on carton-forming stations take their pilot air through M5 ports that face sideways inside the guarding. This elbow turns the Dia 4 polyurethane drop 90 degrees away from the moving jaw, keeping the tube out of the stroke path without an extra adapter.
Is the Airtac PLL L-Type Extended Thread Connector PLL4M5D-S the Right Part?
On the M5 ladder for PLL, only Dia 4 and Dia 6 exist, so this is the smallest part available: there is no Dia 3.2 or 4 mm sibling below it, and the single step up is the PLL6M5D-S, which gains tube bore for slightly freer flow to the same M5 port. If you can move the port itself to a 1/8 PT thread, the PLL 1/8 ladder starts at this same Dia 4 and runs to Dia 10, so a PLL401-S covers identical tubing on a bigger thread. Match the port first, then the tube: a Dia 4 chuck will not grip 5/32 inch or 3 mm tube, it holds exactly 4 mm OD.
Choose the PLL shape over PL when the port is recessed, flanked by a manifold wall, or hidden behind a guard, and the extra neck length is what lets you install and later release the fitting. For a straight entry with no direction change, a PC or POC connector is the lighter answer; for bulkhead pass-through, use PMF instead.
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-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature range of -20 to +70 C. The fitting takes Dia 4 mm soft nylon or polyurethane tube on one side and presents an M5x0.8 male thread (PT-family standard, sealed by a gasket) on the other, with a SUS304 stud and a black PBT elbow body.
No. On extended male elbows the -S option upgrades only the male stud to SUS304 stainless steel; the elbow body stays PBT (black on this D version), with a POM release button and chuck, aluminium-alloy guide, stainless spring gasket and NBR O-ring. Pressure, vacuum and temperature ratings are identical to the standard PLL4M5D, and the published dimensions do not change either, so the two parts are interchangeable in a design.
