About the Airtac PLL L-Type Extended Thread Connector PLL603
The PLL603 is an AirTAC PLL extended male elbow in the one-touch resin and brass family. It joins Dia 6 mm soft nylon or polyurethane tube to a 3/8 inch PT male port at a right angle, with a longer threaded stud than the standard PL male elbow so the fitting stands proud of recessed or counterbored ports. Push the tube straight in and the stainless spring gasket and chuck grip it; press the POM release ring to free it.
This is the resin profile, not the metal BP line: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. The elbow body is PBT with a brass stud, the chuck and button are POM, and the 3/8 inch thread arrives with sealant already applied so PTFE tape is not needed on the 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 PLL603 Is Used
Recessed cylinder ports on palletiser gantries
Palletiser clamp cylinders often sit inside machined pockets where a standard elbow shroud fouls the casting. The PLL603 extended stud clears the pocket wall while turning the Dia 6 drop line 90 degrees.
Pick-and-place arms in electronics assembly
On SMT pick-and-place heads, 6 mm tube runs are routed down the arm to save drag. This elbow lands the 3/8 inch valve or manifold outlet and points the tube along the arm axis without a kink.
Manifold branch outlets on bottling lines
Wash-down safe air manifolds on filling machines commonly use 3/8 inch branch ports feeding thin 6 mm runs to small actuators. The extended body keeps the tube clear of adjacent valve bodies.
Is the Airtac PLL L-Type Extended Thread Connector PLL603 the Right Part?
On the PLL 3/8 inch row, Dia 6 is the smallest tube offered - there is no Dia 4 option at this thread, so if you need a 4 mm tube step down to a 1/4 inch thread part such as PLL602. Stepping up, PLL803 takes Dia 8 tube on the same 3/8 inch port and roughly halves the air velocity in the line for the same compressor output. Note the family ceiling: PLL in 1/2 inch thread exists only in Dia 10 and Dia 12, so this 3/8 inch size is as far as a Dia 6 line can go up in thread.
Match the 3/8 inch PT stud to the port before anything else - an extended elbow on a 1/4 inch port will bottom out or leak at the shoulder. The tube wall matters too: the Dia 6 bore must match exactly, since a 1/4 inch tube will not seat in the Dia 6 chuck and will blow off under pressure. Where space beside the port is genuinely tight rather than recessed, the shorter PL603 may fit better than this extended body.
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 PLL603 FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. This part is a Dia 6 mm one-touch tube socket on a 3/8 inch PT male extended elbow, resin body with a brass stud, grey as standard.
No. AirTAC ships threaded one-touch parts with sealant pre-applied to the stud, so the PLL603 screws straight into a PT port. Avoid adding tape over the factory sealant - excess material can shed into the air line and lodge in a downstream valve. Hand-tighten plus a firm quarter turn is normally enough to seat the shoulder against the port face.
