About the Airtac PLL L-Type Extended Thread Connector PLL1202D
The PLL1202D is an AirTAC PLL extended male elbow: a 90 degree one-touch fitting that joins Dia 12 mm soft nylon or polyurethane tubing to a 1/4" PT male thread. Unlike the standard PL elbow, the extended body stands the thread further off the tube axis, so there is room to get fingers or a tool onto the port and the tube still leaves the fitting square. To connect, push the tube firmly into the chuck until it bottoms; the stainless spring gasket and POM chuck grip it for a pressure-tight seal. Press the POM release ring toward the body to free the tube for removal.
This is the black (D suffix) version, which on the PLL family means the elbow body itself is moulded in black rather than the standard grey. It belongs to the resin one-touch range, not the metal BP line: working pressure 0-1.0 MPa, vacuum to -750 mmHg, proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. The male thread arrives pre-coated with sealant, and the brass stud behind the PBT body threads straight into a PT port without extra tape.

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 PLL1202D Is Used
Injection moulding machine clamp circuits
Large clamp and ejector cylinders on moulding machines commonly carry 1/4" PT ports, and Dia 12 mm tubing feeds their higher air demand. The extended elbow keeps the tube clear of the bolster so it does not kink against the platen.
Palletiser gripper plumbing behind guards
In a robotic palletising cell, vacuum and gripper lines turn 90 degrees in cramped spaces between the frame and safety guarding. The extended body leaves room to press the release ring even when the fitting sits close to the guard panel.
Screen printing machine head air feeds
Print head lift cylinders and squeegee actuators on textile screen printing lines use 1/4" threaded ports. The black body hides cleanly against the dark machine frame, and the elbow routes the drop tube vertically away from ink splash zones.
Is the Airtac PLL L-Type Extended Thread Connector PLL1202D the Right Part?
Dia 12 mm is the largest tube this PLL family takes on a 1/4" thread, so there is no step up from here on this thread size. The only neighbour below is PLL1102 (Dia 10 mm, 1/4"): stepping down trades bore capacity for a slimmer elbow that suits lighter actuator lines. If the port is 3/8" or 1/2" instead, the PLL ladder continues at PLL1203 and PLL1204 respectively - both exist for Dia 12 mm - so match the thread to the port first and the tube size second.
Dia 12 mm must mean 12 mm outside diameter exactly. A Dia 12 chuck will not seal on 1/2" nominal hose or on any slightly oversized or undersized metric tube; when in doubt, measure the tubing with calipers before ordering. Where the tube must pass through a panel rather than turn off a port, the PM bulkhead connector with an M22x1 locknut is the shape to reach for 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 PLL1202D FAQ
It is an extended male elbow one-touch fitting for Dia 12 mm soft nylon or polyurethane tubing with a 1/4" PT male thread, finished in black. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it holds vacuum down to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the operating temperature range is -20 to +70 C. The male thread arrives with sealant pre-applied for PT ports.
Both turn the tube 90 degrees from the port, but the PLL body extends the threaded stud further out. That stand-off does two jobs: it gives your fingers clearance to reach the release ring when the fitting sits deep in a port cluster, and it keeps the tube exit clear of the port boss so the tubing does not bend sharply where it leaves the chuck. Use the plain PL where space is genuinely tight and the extended PLL where access matters.
