About the Airtac PLL L-Type Extended Thread Connector PLL801D
The PLL801D is an AirTAC PLL extended male elbow - a one-touch fitting that joins Dia 8 mm soft nylon or polyurethane tubing to a 1/8 PT male thread at a right angle. The PLL body carries a longer threaded nose than the standard PL male elbow, so the thread stands proud of cylinder head castings, manifold bosses and valve plates instead of sinking into them. To connect, push the tube square into the chuck until it seats; the stainless spring gasket and POM chuck grip it under load, and pressing the release ring frees it again.
This is the resin one-touch line, rated 0-1.0 MPa working pressure (0-10 kgf/cm2), 1.5 MPa proof pressure, -750 mmHg vacuum and -20 to +70 C. The -M style mini parts aside, the PLL body is PBT with a brass stud, a POM release button and an NBR seal, and the male thread arrives with sealant already applied. On PLL the trailing D changes the whole body to black, not just the button as on the PC and POC straight connectors.

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 PLL801D Is Used
Swing clamp cylinder ports
On a swing clamp or power clamp unit the port often sits inside a machined pocket below the flange face; the PLL801D long nose bridges that pocket so the hex sits where a wrench can reach it.
Pneumatic manifold branching
Feeding a Dia 8 lateral off a valve manifold with 1/8 PT tapped stations - the elbow turns the tube run sideways across the manifold instead of fouling adjacent solenoid valves.
Packaging machine seal jaws
Heat-seal jaw cylinders on a horizontal bagger sit close to the frame; a right-angle fitting with the longer PLL nose keeps the Dia 8 airline flat against the jaw arm and clear of the seal area.
Is the Airtac PLL L-Type Extended Thread Connector PLL801D the Right Part?
PLL801D sits mid-way up the 1/8 PT ladder for this prefix, which runs Dia 4, 6, 8 and 10 - note Dia 12 is not offered on a 1/8 PLL. Step down to PLL601 to feed small actuator ports where flow demand is light; step up to PLL1001 when a longer cylinder or larger valve port needs the extra bore. If the 1/8 port feels undersized for your Dia 8 circuit, move to PLL802 (1/4 thread) rather than restricting the tube.
Choose this extended shape over a plain PL when the fitting must clear a recessed or flanged port, and over a PH universal elbow when you need a fixed 90 degree run rather than a swivelling one. The tube OD must match exactly: an 8 mm fitting will not seal on 5/16 inch or Dia 6 tube, and forcing a mismatch is the usual cause of slow leaks at the chuck.
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 PLL801D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum to -750 mmHg (10 Torr) and a temperature range of -20 to +70 C. It accepts Dia 8 mm soft nylon or polyurethane tube on one side and has a 1/8 PT male thread with factory-applied sealant on the other.
On the PLL series the D converts the body to black - the seal, chuck and ratings are unchanged, so it is purely a visual choice for matching machine components. The more practical spec to check is the nose length: this extended male elbow is longer than a standard PL801, which is exactly why it is specified for recessed ports. If you need the shorter version, order PL801 instead.
