About the Airtac PLL L-Type Extended Thread Connector PLL1003-S
The PLL1003-S is an AirTAC PLL extended male elbow, the longer-nosed version of the PL elbow, joining Dia 10 mm soft nylon or polyurethane tubing to a 3/8in PT male thread. The extended body stands the hose exit further off the port face than a standard PL, which keeps a 10 mm line clear of boss faces, guards and adjacent fittings. Push the tube in and the internal chuck grips it; press the POM release ring to free it.
This is the -S stainless variant. On the PLL family the body remains PBT and the male stud is SUS304, so the corrosion exposure sits where the part meets the port rather than in the plastic shell. Ratings are unchanged from the standard resin line: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, -20 to +70 C. The thread arrives with sealant already applied, and the release button, chuck and guide are POM, aluminium alloy and stainless respectively with an NBR O-ring.

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 PLL1003-S Is Used
Wash-down rinse frame on a food line
The SUS304 male stud resists corrosion where the fitting threads into a stainless manifold on a rinse or washdown station, while the PBT body keeps the Dia 10 hose exit standing proud of wet framework so it can drain and dry instead of sitting in pooled water.
Cylinder port inside a tight machine guard
On a clamping cylinder mounted behind sheet-metal guarding, the extended nose of the PLL1003-S lifts the 3/8in connection and the Dia 10 hose clear of the head cap, so the 90 degree turn can be made without the tube kinking against the guard wall.
Valve manifold branch to a rotary actuator
Where a 3/8in port on a solenoid manifold sits close to neighbouring valves, the elongated elbow gives a 10 mm branch line room to clear the adjacent fittings before turning toward a rotary actuator or air table.
Is the Airtac PLL L-Type Extended Thread Connector PLL1003-S the Right Part?
On the 3/8in PT row of the PLL ladder, Dia 10 sits between Dia 8 (PLL803) below and Dia 12 (PLL1203) above. Dropping to 8 mm buys a slimmer hose path and a lighter bend radius; stepping up to 12 mm moves more air per metre of run, which matters on long feeds to large-bore actuators. Tube OD must match exactly: a Dia 10 chuck will not seal on 1/4in or 12 mm tube. Choose PLL over PL when the port face is recessed, shrouded or crowded, since the longer stud gives the hose a clean run-off; choose a PH universal elbow instead if the angle has to be set freely rather than fixed at 90 degrees. Match the 3/8in thread to a 3/8in PT port, or change the last two digits of the code for 1/4in (02) or 1/2in (04).
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 PLL1003-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, operating temperature -20 to +70 C. It joins Dia 10 mm soft nylon or polyurethane tube to a 3/8in PT male thread. The -S suffix makes the male stud SUS304 while the body stays PBT; pressure and temperature ratings are identical to the standard PLL1003.
No. On the elbow families that take the -S suffix, including PLL, only the male stud is SUS304; the body remains PBT. Full stainless bodies are offered on the PC and POC straight connectors, not on PLL. The release button and chuck stay POM, the guide is aluminium alloy, the spring gasket is stainless and the O-ring is NBR, so the fitting should still be paired with tubing rated for the same -20 to +70 C window.
