About the Airtac PLL L-Type Extended Thread Connector PLL601D-S
The PLL601D-S is an AirTAC PLL extended male elbow: a right-angle one-touch fitting that joins Dia 6 mm soft nylon or polyurethane tubing to a 1/8in PT male thread, with the D suffix giving a black body. The extended pattern carries a longer threaded shank than the standard PL elbow, so the tube stands clear of the port boss instead of bending hard against it. Push the 6 mm tube home and the stainless spring gasket and chuck grip it; press the POM release ring to free it again.
The -S suffix makes the threaded stud SUS304 stainless steel while the elbow body stays PBT, so treat this as a stainless-stud part rather than a solid stainless body. Ratings are unchanged from the resin line: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. The 1/8in thread arrives with sealant pre-applied, so it seals straight into a PT port without extra tape.

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 PLL601D-S Is Used
Cylinder ports behind tight guards
The extended shank carries the 6 mm drop away from a cylinder head port so the tube clears the guard plate instead of kinking against the boss.
Plating and wash-down stations
The SUS304 stud resists splash and rinse chemistry on a plating line rinsing station, where a plain brass stud thread would corrode and seize in the port.
Valve manifold pilot drops
A 1/8in PT pilot port on a control valve manifold takes the elbow directly, feeding a 6 mm signal line down to a pilot actuator.
Is the Airtac PLL L-Type Extended Thread Connector PLL601D-S the Right Part?
On the PLL ladder at 1/8in thread, Dia 6 sits between PLL401 (Dia 4) below and PLL801 (Dia 8) above. Stepping down to Dia 4 buys the smallest bend radius in cramped panels; stepping up to Dia 8 lowers restriction to a valve or cylinder feed. Above Dia 8, the 1/8in run ends - Dia 10 and Dia 12 elbows move to the 1/4in thread codes such as PLL1002. Tube OD must match exactly: this chuck will not hold 1/4in tube even though the nominal sizes look close.
Pick PLL over PL when the tube must clear a guard, manifold wall or cylinder boss; pick PL if space is tight and a short shank is better. Confirm your port is truly PT before ordering - this catalogue documents PT only.
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 PLL601D-S FAQ
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. This SKU is the extended male elbow for Dia 6 mm soft nylon or polyurethane tube with a 1/8in PT male thread, black body, with a SUS304 stainless stud. The -S variant carries the identical pressure, vacuum and temperature ratings as the standard PLL601D.
No. The elbow installs exactly like the standard version: hand-tighten the sealant-coated 1/8in PT stud into the port, then push the Dia 6 tube in until it bottoms to lock. The differences are material only - the stud is stainless 304 for corrosion resistance, and the D suffix makes the body black. Do not run this part above 70 C; for high-temperature circuits you need the metal BPC-family line instead, which is rated to 150 C but only 0.9 MPa.
