About the Airtac PLL L-Type Extended Thread Connector PLL802D
The AirTAC PLL802D is an extended male elbow in the resin one-touch range: a Dia 8 mm tube socket set at 90 degrees to a 1/4 in PT male thread, carried on an extended neck that stands the tube entry away from the mounting face. The D suffix makes this the black version, and on the PLL series that means the whole body and elbow are moulded in black, not just the release button as on PC and POC connectors.
Assembly is genuinely tool-free: push the soft nylon or polyurethane tube into the socket until it bottoms, the POM chuck inside grips it against the stainless spring gasket and NBR O-ring, and pressing the release ring lets it pull free. This is the resin and brass spec profile, so it is rated 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. The 1/4 in thread arrives with sealant already applied, and the brass stud with PBT threaded section screws straight into a standard PT port.

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 PLL802D Is Used
Pneumatic press cylinder ports
On a bench-mounted pneumatic press, the 1/4 in port sits in a recess behind the cylinder head. The PLL802D extended neck holds the Dia 8 tube clear of the head hex before the elbow turns it along the frame, so the run can be routed without kinking at the port.
Pick-and-place gripper feed
On a robotic pick-and-place arm, the Dia 8 vacuum and air lines must turn 90 degrees immediately after leaving the wrist manifold. The black body also disappears against the anodised arm housings, which matters on vision-inspected cells.
Valve manifold outlet risers
On a solenoid valve manifold with 1/4 in outlets facing sideways inside a control cabinet, the extended male elbow lifts the Dia 8 tube off the manifold face so neighbouring valve connectors and their coils stay accessible for servicing.
Is the Airtac PLL L-Type Extended Thread Connector PLL802D the Right Part?
Sizing both ways on the 1/4 in ladder: one step down is PLL602 (Dia 6 tube) for lighter actuator lines, one step up is PLL1002 (Dia 10) when the branch feeds a larger bore cylinder. Dia 8 on a 1/4 in thread is the balanced pairing - the bore matches what a 1/4 in port can feed without throttling. On the thread axis, PLL802D also exists as PLL801 (1/8 in thread) for compact valve manifolds and as PLL803 (3/8 in) for larger port blocks.
Choose the extended PLL over the standard PL elbow when the tube must clear a raised boss, a guard panel or the hex of an adjacent fitting before turning. Pick a PH universal elbow instead if the approach angle needs adjusting on the machine. Whichever shape you land on, the tube OD must match exactly - a Dia 8 socket will not seal or hold 1/4 in (6.35 mm) hose, and forcing it is the classic cause of blow-off under pressure.
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 PLL802D FAQ
It is an AirTAC PLL extended male elbow for Dia 8 mm soft nylon or polyurethane tube with a 1/4 in PT male thread, black body (D suffix). Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. The release button and chuck are POM, the guide is aluminium alloy, the spring gasket is stainless, the O-ring is NBR, and the thread carries pre-applied sealant.
The PLL has an extended neck, so the tube entry stands off the mounting face before turning 90 degrees - useful where a boss, panel or adjacent fitting would otherwise trap the tube. On the 1/4 in thread AirTAC lists Dia 4, 6, 8, 10 and 12 tube sizes, so you can step this exact shape across the whole medium-duty ladder. Note that the 1/2 in thread version of the PLL is only made in Dia 10 and Dia 12, so large-tube and large-thread upgrades do not always pair one to one.
