About the Airtac PLL L-Type Extended Thread Connector PLL602
The PLL602 is an AirTAC PLL extended male elbow, a one-touch fitting that joins Dia 6 mm soft nylon or polyurethane tubing to a 1/4in PT male thread. Compared with the standard PL male elbow, the PLL body is extended further along the thread axis, so the hex flats and the tube exit sit clear of the mounting face. To make the joint, push the tube straight into the chuck until it bottoms out; the stainless spring gasket and chuck teeth grip the OD and the NBR O-ring seals it. Pressing the POM release ring unclamps the tube for removal.
This part belongs to the resin and brass one-touch line, not the metal BPC family: working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a service temperature of -20 to +70 C. The 1/4in male thread is brass with sealant pre-applied at the factory, so PTFE tape is not needed on the port; the release button and chuck are POM and the internal guide is aluminium alloy. Note that M5 sizes in this family seal with a gasket instead of thread sealant - the PLL602 does not need that consideration.

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 PLL602 Is Used
Cylinder ports behind guards
On a clamp cylinder recessed inside a sheet-metal guard, the PLL602's extended body keeps the 6mm tube exit and release ring clear of the port boss, so a technician can thumb-release the tube without pulling the guard or reaching into the cavity with a tool.
Vacuum cup drop lines
At -750 mmHg (10 Torr) negative pressure, the fitting holds vacuum as well as pressure, so it suits the drop from an ejector manifold to a suction cup on a carton-handling head, with the elbow turning the 6mm line to follow the cup's vertical stroke.
Pneumatic stoppers on conveyor frames
A pop-up stopper or diverter on an assembly conveyor needs its supply line running parallel to the frame rail; the PLL602 elbows the 6mm tube sideways off a 1/4in PT port tapped into the stopper body, keeping the line inside the guarding profile.
Is the Airtac PLL L-Type Extended Thread Connector PLL602 the Right Part?
On the 1/4in PT thread, AirTAC makes the PLL ladder in Dia 4, 6, 8, 10 and 12 mm, so the PLL602 sits second from the bottom: step down to a PLL402 for 4 mm signal or pilot lines, or up to a PLL802 when the branch feeds a larger-bore cylinder and you want lower restriction through the bore. Thread stays fixed across that ladder, so you re-pick the tube side only. If reach is not needed, the plain PL602 is the shorter-body alternative on the same sizes.
Tube OD must match exactly. A Dia 6 mm one-touch chuck will not seal on nominal 1/4in tubing, which measures 6.35 mm - mixing inch tube into a metric fitting is the most common leak cause on mixed-standard machines. Match the PT thread to the port by hand first; a 1/4in PT male will start into an NPT female by about a turn and then jam, so never force it.
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 PLL602 FAQ
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. This SKU is the extended male elbow joining Dia 6 mm soft nylon or polyurethane tube to a 1/4in PT male thread, from AirTAC's resin and brass one-touch range with a POM release button and NBR O-ring seal.
Both share the same tube and thread ladder on a 1/4in port (Dia 4, 6, 8, 10 and 12 mm) and identical ratings; the PLL simply extends the male body further from the elbow axis. Choose PLL when the port sits flush in a bracket or housing and you need wrench access on the hex plus finger room around the release ring; choose PL when panel space is tight and the extra projection would foul a moving part.
