About the Airtac PLL L-Type Extended Thread Connector PLL1204-S
The PLL1204-S is AirTAC's PLL extended male elbow in its stainless-stud finish: a one-touch fitting that joins Dia 12 mm soft nylon or polyurethane tubing to a 1/2in PT male thread set at 90 degrees on a lengthened shank. Push the tube home and the stainless spring gasket and POM chuck grip it for a sealed joint; press the release ring and the tube frees for repositioning. The extended thread length is the whole point of the PLL prefix - it clears panel walls, guards and shrouds that a standard PL elbow would butt up against.
The -S suffix makes the stud SUS304 while the elbow body stays glass-filled PBT with a POM release button, aluminium-alloy guide and NBR O-ring - the ratings are identical to the grey standard part: 0-1.0 MPa working pressure, 1.5 MPa proof, -750 mmHg vacuum and -20 to +70 C. Every threaded AirTAC part in this catalogue arrives with sealant already on the thread, so no extra tape or dope is needed on the 1/2in port.

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 PLL1204-S Is Used
Wash-down conveyor air drops
Bottling and canning lines hose down their frames daily. A Dia 12 feed run down a stainless conveyor leg into a 1/2in port benefits from the SUS304 stud resisting wash-down corrosion at the joint that stays wet longest - the elbow at the bottom of the drop.
Clamp cylinder on a machining fixture
Large pneumatic swing clamps on CNC fixtures breathe hard and sit close to riser blocks and guard rails. The Dia 12 bore keeps flow losses low and the PLL's extended 1/2in thread clears the fixture plate where a standard PL elbow would foul.
Plating line rinse manifold
Electroplating and rinse stations use copper-free plumbing to avoid metal contamination in chemical baths. With a SUS304 stud and PBT body the PLL1204-S keeps copper out of the wet zone while the one-touch connection lets technicians reroute Dia 12 rinse lines during changeover.
Is the Airtac PLL L-Type Extended Thread Connector PLL1204-S the Right Part?
On the 1/2in PT thread, PLL exists in only two tube bores: Dia 10 and Dia 12. This SKU is the top of that ladder - there is no Dia 14 in the catalogue - so the only neighbour down is PLL1004-S on Dia 10 tube. Stepping down trims the bore for lighter-demand actuators; staying at Dia 12 keeps the line area up for high-consumption cylinders over long runs. Remember the ladder also extends sideways: 1/8in and 1/4in PLLs cover 4-12 mm tube if your port is smaller.
Tube OD must match exactly - a Dia 12 chuck will not seal on 1/4in (6.35 mm) inch tube even though the difference looks trivial. If you need to pass this line through a sheet-metal wall instead of branching off it, the PLM bulkhead male elbow with its M22x1 locknut thread (the Dia 12 size) is the shape that does that job.
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 PLL1204-S FAQ
It is an extended male elbow one-touch fitting for Dia 12 mm soft nylon or polyurethane tube with a 1/2in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa and operating temperature -20 to +70 C. The -S variant has a SUS304 stud on a PBT body; every pressure and temperature figure matches the standard grey PLL1204 exactly.
No. The dimension tables for the -S parts match the standard line, so the elbow profile, thread length and Dia 12 grip geometry are unchanged. Only the stud material moves to SUS304, which adds corrosion resistance and copper-free construction at the threaded interface. Note that the 1/2in PT thread in this series is offered only with Dia 10 or Dia 12 tube - there is no smaller or larger tube option at this thread size.
