About the Airtac PLL L-Type Extended Thread Connector PLL1204D
The PLL1204D is an AirTAC PLL extended male elbow, the right-angle one-touch fitting whose male thread sits on a longer shank than the standard PL. It joins Dia 12 mm soft nylon or polyurethane tubing to a 1/4" PT port, and the D suffix means the body is moulded in black rather than the standard grey. Push the tube in and the stainless spring gasket plus chuck grip it along the bore; press the POM release ring and the tube comes straight back out.
This is the resin and brass spec profile, not the metal BP line: 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. Inside are a POM button and chuck, an aluminium-alloy guide and an NBR O-ring; the threaded parts are PBT over a brass stud. The 1/4" thread arrives with sealant already applied, so it seals on the PT taper 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 PLL1204D Is Used
Valve manifold outlets on a bottling line
The long 1/4" PT shank clears the raised bosses cast around manifold ports, giving the pre-applied sealant enough engaged thread to seal on the PT taper before the Dia 12 supply line turns 90 degrees out to the filler heads.
Rotary actuator feed on a palletizer
Right-angle exit directly off the actuator port keeps the Dia 12 line tight to the machine frame, away from the rotating sweep of the turntable, where a straight connector would snag hose routing.
Conveyor gate cylinder in a guarded zone
Where the divert gate cylinder sits flush behind a sheet-metal guard, the extended shank brings the elbow proud of the bracket so the release ring stays reachable for tube changes without opening the guard.
Is the Airtac PLL L-Type Extended Thread Connector PLL1204D the Right Part?
On the 1/4" PT ladder for PLL, the step down from Dia 12 is PLL1002 (Dia 10 tube), and Dia 12 is the largest tube this thread takes, so there is no step up on 1/4" - you would move to PLL1203 (3/8" PT) or PLL1204A (1/2" PT) to stay on Dia 12 tubing with a bigger port. Stepping down to Dia 10 buys nothing on a 1/4" port; Dia 12 uses the full bore available at this thread. Note that if you ever specify the 1/2" version, Dia 10 is the smallest tube it accepts. Tube OD must match exactly: this chuck is cut for 12 mm and will not seal 1/2" (12.7 mm) tubing. Choose the extended PLL shank over a plain PL when the port sits recessed in a casting or manifold face and you need more thread engaged and more wrench room.
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 PLL1204D FAQ
AirTAC PLL1204D: extended male elbow one-touch fitting for Dia 12 mm soft nylon or polyurethane tubing with a 1/4" PT male thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. Black (D) PBT body over a brass stud, POM chuck and button, NBR O-ring, thread supplied with sealant. These are the standard resin-profile ratings - the stainless -S version uses exactly the same figures.
Both seal the same way, but the PLL1204D's longer thread shank matters on a 1/4" PT port recessed in a manifold face, thick bracket or casting: you get more engaged thread, room for a wrench, and the black body stands off far enough that the release ring can be pressed with a fingertip. If the port is flush and accessible, a standard PL1204 does the same job in a shorter length.
