About the Airtac PLL L-Type Extended Thread Connector PLL1004-S
The AirTAC PLL1004-S is a stainless-stud extended male elbow from AirTAC's resin one-touch range. It joins a Dia 10mm tube to a 1/2in PT male thread, and the extended nose sits the elbow body further off the port face than the standard PL elbow, giving spanner clearance in cramped installs. Push the tube home and the internal chuck grips it; press the release ring to free it. No tools touch the tube joint.
This -S variant keeps the PBT elbow body but carries a SUS304 stud, so the threaded stem shrugs off splash and mist that would pit plain brass. Ratings follow the standard resin profile: 0 to 1.0 MPa working, 1.5 MPa proof, vacuum to -750 mmHg (10 Torr), and -20 to +70 C with soft nylon or polyurethane tube. The 1/2in thread arrives with sealant already applied, so it seats straight into the 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 PLL1004-S Is Used
Dairy bottle-rinse tunnel
An extended elbow feeds the rinse-station gripper cylinder where the port sits close to the machine frame; the SUS304 stud stands up to daily caustic spray that would corrode a plain brass stem.
Electroplating jig lift
At a plating shop lift cylinder, acid mist hangs in the air above the tank. The 1/2in PT sealed stud threads into the cylinder head and the extended body points the Dia 10 drop line away from the bath.
Marine deck winch control
Salt-fog on a workboat deck pits unprotected brass fast. The stainless-stud elbow joins the Dia 10 pilot line at the winch valve block and takes the tube run neatly around the housing.
Is the Airtac PLL L-Type Extended Thread Connector PLL1004-S the Right Part?
At a 1/2in thread, AirTAC makes the PLL in only two tube sizes: Dia 10 and Dia 12. That makes the PLL1004-S the smallest-tube option under a half-inch port on this prefix; step up to the PLL1204-S if your run is Dia 12. If your port is actually 3/8in, drop to the PLL1003-S and keep the same Dia 10 tube. The tube OD must match exactly - a Dia 10 chuck will not seal on 3/8in or 12mm tubing.
Choose the extended elbow over a straight connector or a standard PL when the port sits under a shoulder, guard plate, or boss and you need wrench room to start the thread and body clearance for the tube bend. Where you need to pass through a panel instead, the PLM bulkhead male elbow is the shape to look at.
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 PLL1004-S FAQ
This fitting is a Dia 10mm to 1/2in PT extended male elbow. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure goes to -750 mmHg (10 Torr), and proof pressure is 1.5 MPa. Service temperature is -20 to +70 C with soft nylon or polyurethane tube. The -S suffix gives you a SUS304 stud; the elbow body remains PBT. Ratings are identical to the non-stainless PLL1004.
No. On the PLL family the -S upgrade replaces the stud with SUS304 stainless, but the elbow body stays PBT with the standard POM release ring and NBR seal. That is deliberate: the thread end is where corrosion attacks first, so the metal that meets the port is stainless while the body keeps the resin one-touch mechanism. Do not expect Ra finishes or food certifications - AirTAC publishes none for this variant.
