About the Airtac PLL L-Type Extended Thread Connector PLL803D
The PLL803D is an AirTAC PLL extended male elbow, a one-touch resin fitting that joins Dia 8 mm tubing to a 3/8in PT male thread. Compared with a standard PL elbow, the extended nose gives extra stand-off from the mounting face, so the outlet clears hex flats, locknuts and curved port bosses. Push the tube home and the stainless spring gasket and chuck grip it; press the POM release ring to free it.
This is the standard resin and brass profile, rated 0-1.0 MPa (0-10 kgf/cm2), -750 mmHg (10 Torr) vacuum, with a 1.5 MPa proof pressure and a -20 to +70 C window. The body is PBT on a brass stud, and the thread arrives from the factory pre-coated with sealant, so no extra tape or paste is needed. On the PLL series the trailing D turns the whole body black, not just the release button, which suits dark machine frames where grey fittings stand out.

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 PLL803D Is Used
Gantry pick-and-place port elbow
On a Cartesian pick-and-place gantry the extended nose offsets the Dia 8 drop line from a closely mounted Z-axis cylinder port, leaving wrench room beside the 3/8in stud.
Manifold branch to clamp actuator
Take a Dia 8 branch straight off a 3/8in air-prep or valve manifold on a bottling line, the elbow turning the drop at the port instead of forcing a sharp bend into the tubing.
Baggage sorter pusher cylinder
Airport baggage-sorter pusher cylinders often sit tight against guide rails; a PLL803D lets the 3/8in port line exit away from the rail into Dia 8 polyurethane tubing.
Is the Airtac PLL L-Type Extended Thread Connector PLL803D the Right Part?
Within the PLL 3/8in row AirTAC also lists Dia 6 and Dia 10, so step down to PLL603 when the line feeds a smaller gripper or valve port, or up to PLL1003 where a wider bore carries more air - capacity follows the tube bore (AirTAC publishes only a characteristic curve, no flow figure). If your machine port is 1/4in instead, the matching Dia 8 part is PLL802.
Tube OD must match exactly: a Dia 8 chuck will not seal on 1/4in or 5/16in tube, and mixing metric and inch tubing is the most common cause of slow leaks at one-touch joints. For through-panel mounting, a PMF bulkhead connector or PLM bulkhead elbow is the better shape.
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 PLL803D 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. Size: Dia 8 mm tube x 3/8in PT male thread, black body. Applicable tubing is soft nylon or polyurethane of exactly 8 mm OD.
On the PLL series the D recolours the body to black as well as the release button; the grey PLL803 is dimensionally identical. Ratings, materials and the pre-applied thread sealant are unchanged, so choose D for appearance on dark machinery, not for performance.
