About the Airtac PLL L-Type Extended Thread Connector PLL1204
The PLL1204 is an AirTAC PLL extended male elbow: a one-touch fitting that joins Dia 12 mm soft nylon or polyurethane tube to a 1/2 in PT male thread and turns the line 90 degrees. The extension between the thread and the elbow body puts the tube entry clear of the port face, leaving room for a spanner on the flats and keeping the tubing from fouling guards, manifolds or cylinder shoulders. Push the tube home and the stainless spring gasket chuck grips it; press the POM release ring and it frees again.
This is the resin one-touch profile, not the metal BP line: working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa and a temperature range of -20 to +70 C. The body is PBT with a brass stud, and the 1/2 in PT thread arrives with sealant already applied so the joint seals on assembly. Dia 12 is the largest tube this fitting family carries on a 1/2 in thread.

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 Is Used
Blow-moulding machine clamp cylinders
Large clamp and take-off cylinders on PET blow-moulding machines commonly run Dia 12 lines off 1/2 in manifold ports. The extended elbow clears the cylinder shoulder so the tube leaves straight into the machine guard.
Conveyor take-up stations
Pneumatic belt-tensioning cylinders on heavy conveyor lines use a big-bore feed. The PLL1204 turns the 12 mm line down along the stringer, away from the moving belt edge.
Press-tool ejection circuits
Air-driven ejectors and part-blowoff nozzles on mechanical presses need high flow from a short 1/2 in port connection. The extended body gives the wrench room to torque the stud into a crowded die plate.
Is the Airtac PLL L-Type Extended Thread Connector PLL1204 the Right Part?
Dia 12 is the top of the tube ladder on a 1/2 in PLL thread - the only size above it does not exist, so check the air demand of your actuator rather than stepping up. Step down to the PLL1004 (Dia 10 tube, same 1/2 in thread) when the cylinder port or the manifold branch is Dia 10; the fitting footprint stays similar but the bore and the airflow it can carry drop. On thread, the neighbour below 1/2 in for Dia 12 tube is the PLL1203 in 3/8 in PT - choose it when the port is a 3/8 in cavity, and remember tube OD must match the fitting exactly, so a Dia 12 part will not grip 1/2 in imperial hose or a Dia 10 line.
If the 90 degree turn needs to point in any direction rather than one fixed way, the PHW double universal male elbow is the better shape. For a pass-through a panel wall, use a PLM bulkhead male elbow instead - the Dia 12 locknut thread on that series is M22x1.
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 FAQ
The PLL1204 is an AirTAC PLL extended male elbow for Dia 12 mm tube with a 1/2 in PT male thread. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), it holds vacuum to -750 mmHg (10 Torr), proof pressure is 1.5 MPa and the operating temperature range is -20 to +70 C. It accepts soft nylon or polyurethane tube of exactly Dia 12 mm OD.
No. AirTAC ships every threaded one-touch part with sealant already applied to the 1/2 in PT male thread, so it seals on assembly. M5 sizes in the same family are the exception - those use a sealing gasket instead. Note also that PT is the only thread standard in this catalogue, so a BSPP or NPT version is not available.
