About the Airtac PLL L-Type Extended Thread Connector PLL1203D
The PLL1203D is an AirTAC extended male elbow, the long-stud version of the standard PL fitting. It joins Dia 12 mm soft nylon or polyurethane tubing to a 3/8in PT male thread, and the elongated body lets the elbow stand proud of a port or sheet-metal panel so the tube can leave at 90 degrees without fouling the surrounding hardware. Push the tube home and the internal chuck grips it; press the POM release ring to free it. The threaded stud arrives with sealant already applied, so no additional tape or compound is needed on the PT thread.
This is a resin-line part: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. The body is PBT on a brass stud, with a stainless spring gasket and NBR O-ring at the grip. The D suffix on this series means the whole body is moulded black, not just the release button - worth knowing if you are colour-coding machine circuits.

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 PLL1203D Is Used
Cylinder ports behind machine guarding
On a packaging line the cylinder port often sits in a recess or behind a guard plate. The extended PLL1203D stud stands the elbow clear of the plate so the Dia 12 tube can turn 90 degrees without kinking against the sheet metal.
Recessed manifold outlets on blow-moulding machines
Blow-moulding valve manifolds frequently have deep counterbores around the outlet. A standard PL elbow bottoms out here; the longer PLL body bridges the recess and keeps the Dia 12 line clear of the casting.
Heavy actuator circuits on sawmill conveyors
Conveyor stop and clamp actuators in timber processing commonly run Dia 12 polyurethane lines. The black PBT body is easy to trace against grey machine paint when commissioning or fault-finding the circuit.
Is the Airtac PLL L-Type Extended Thread Connector PLL1203D the Right Part?
On the PLL 3/8in ladder the step down is PLL1003, which takes Dia 10 mm tube on the same thread; stepping up to Dia 12 makes this the largest tube the 3/8in stud supports. If your port is 1/2in PT, PLL1204 carries the same Dia 12 tube on the bigger thread, so you can hold the bore and change the interface instead of the hose. Match the stud to the port size already drilled and tapped - a 3/8in stud into a 1/2in port will not seal on the thread shoulder. Tube OD must match exactly: a Dia 12 chuck will not reliably hold a nominal 1/2in (12.7 mm) hose, and no imperial tube belongs on this fitting. If you actually need to pass through a panel wall rather than reach past one, the bulkhead-style PLM is the shape to look at instead.
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 PLL1203D 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. This SKU joins Dia 12 mm soft nylon or polyurethane tube to a 3/8in PT male thread, in a black PBT body on a brass stud. Flow capacity is published by AirTAC as a characteristic curve only; the practical capacity follows the 12 mm bore.
No on both counts. The chuck in the PLL1203D is cut for a 12 mm outside diameter and will not seal reliably on anything else, including nominal 1/2in hose. For Dia 10 tube on the same 3/8in thread order PLL1003; for a 1/2in PT port with Dia 12 tube, order PLL1204.
