About the Airtac PLL L-Type Extended Thread Connector PLL1004D
The PLL1004D is an AirTAC PLL extended male elbow, the version of the PL elbow family where the male thread is set back from the bend on a raised boss. That stand-off gives a spanner clearance and lets the hose leave the port at 90 degrees without fouling the body it is screwed into. This SKU joins Dia 10 mm soft nylon or polyurethane tube to a 1/2 in PT male thread, and the D suffix makes the whole PBT body black - on the PC and POC straights a D only changes the release button, but on the PLL series it recolours the fitting itself.
It is a resin/brass one-touch part: push the tube home and the stainless spring gasket and chuck grip it against the NBR O-ring, press the POM release ring to free it. Ratings are the standard resin profile - 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. The 1/2 in thread arrives with sealant already on it, so it seals into a tapped PT port straight from the bag.

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 PLL1004D Is Used
Clamp cylinder inside a tight guard
On a pneumatic clamping fixture whose side port sits flush against the machine guard plate, the PLL1004D stands the 1/2 in thread off the face so a spanner fits during install and the Dia 10 hose exits cleanly at 90 degrees.
CNC fixture rotary actuator supply
Feeding a rack-and-pinion rotary actuator on a machining centre fixture, the extended elbow reaches out of a counterbored port so the black PBT body stays visible for inspection and the push-fit connection survives vibration without a tools-based re-tighten.
Palletiser pusher gate actuator
On an end-of-line palletiser, the gate-cylinder port sits under the conveyor frame; the extended male elbow lets the Dia 10 supply line route downward past the frame rail, and the black body matches the machine's dark cabling and hose scheme.
Is the Airtac PLL L-Type Extended Thread Connector PLL1004D the Right Part?
At 1/2 in PT, the PLL ladder offers only Dia 10 and Dia 12 tube - this Dia 10 is the entry size, so there is no smaller tube on this thread. If 12 mm hose is what the machine is plumbed with, step up to PLL1204. If the port is smaller, keep Dia 10 and drop the thread instead: PLL1003 (3/8 in) and PLL1002 (1/4 in) both exist for Dia 10 tube. Whatever you pick, tube OD must match exactly - a Dia 10 chuck will not seal on 3/8 in or 12 mm hose.
Choose PLL over plain PL when the port sits in a recess, behind a boss, or against a surface that would trap a flush elbow and leave no room for a wrench on assembly.
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 PLL1004D FAQ
It is an AirTAC PLL extended male elbow joining Dia 10 mm soft nylon or polyurethane tube to a 1/2 in PT male thread, with a black PBT body (the D suffix). Working pressure 0 to 1.0 MPa, negative pressure -750 mmHg, proof pressure 1.5 MPa, operating temperature -20 to +70 C. The thread ships with sealant pre-applied.
No. One-touch chucks grip one tube OD only, so this fitting holds Dia 10 mm hose and nothing else. If your line is Dia 12, order PLL1204, which is the other size offered on a 1/2 in PT PLL thread. For a 3/8 in hose you would need a different tube size entirely, not a different thread on this part.
