About the Airtac PLL L-Type Extended Thread Connector PLL4M5-S
The PLL4M5-S is AirTAC's PLL extended male elbow from the resin one-touch range, joining Dia 4 mm soft nylon or polyurethane tube to an M5x0.8 male thread. The extended nose holds the thread clear of the elbow shoulder, so a spanner can seat the stud even when the fitting is buried against a machine wall. Connection is a single motion: push the tube home until it bottoms, the stainless spring gasket and chuck grip the OD, and press the release ring to free it. Because this is an M5 size, the thread is sealed by a gasket rather than the pre-applied sealant used on the larger PT threads.
The trailing -S means the SUS304 variant: on PLL fittings the elbow body stays PBT and the male stud is upgraded to stainless steel 304, so the thread that bites into the port will not rust or seize in wet or corrosive air. Ratings are identical to the standard part - working pressure 0-1.0 MPa, vacuum to -750 mmHg, proof pressure 1.5 MPa and a temperature window of -20 to +70 C.

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 PLL4M5-S Is Used
Analytical instrument sample lines
Laboratory analysers and small pneumatic test rigs commonly carry M5x0.8 ports; this elbow turns a Dia 4 sample line 90 degrees inside a crowded instrument frame.
Daily-wiped packaging machinery
On packaging machines cleaned down with caustic wipes each shift, the SUS304 stud resists the pitting that gradually wrecks a plated brass thread.
Compact valve manifold drops
Where a Dia 4 line drops from an M5 valve manifold port straight into a guarding panel, the extended nose leaves room to get a spanner onto the stud.
Is the Airtac PLL L-Type Extended Thread Connector PLL4M5-S the Right Part?
Dia 4 is the smallest tube on the PLL M5 row, so the only neighbour is PLL6M5-S one size up; the wider Dia 6 bore feeds a little more air to the same M5 port, and nothing below Dia 4 exists in this thread. If your port is 1/8 in PT rather than M5x0.8, the equivalent Dia 4 part is PLL401-S. Check the port spec before ordering: an M5 fitting carries a gasket seal, while the 1/8 in version relies on thread sealant, and they are not interchangeable.
Tube OD must match exactly - a Dia 4 chuck will not grip 1/4 in (6.35 mm) hose, and no adapter changes that. If the line has to pass through a panel instead of ending on a port, the bulkhead PLM in Dia 4 with its M12x1 locknut is the right shape, not this elbow.
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 PLL4M5-S FAQ
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. This SKU connects Dia 4 mm soft nylon or polyurethane tube to an M5x0.8 male thread (PT thread standard on this catalogue, M5 sealed by gasket). The elbow body is PBT and the male stud is SUS304 stainless steel.
No. The one-touch chuck is machined for a single tube OD, so only Dia 4 mm soft nylon or polyurethane seals correctly here - 1/4 in (6.35 mm) hose will not seat and Dia 5 is not a made size. On the M5 thread the PLL series exists only in Dia 4 and Dia 6, so PLL6M5-S is the next step up.
