About the Airtac PLF L-Shaped Female Thread Adapter PLF803D
The AirTAC PLF803D is a resin-bodied one-touch female elbow in the PLF series. It turns a run of Dia 8 mm soft nylon or polyurethane tubing through 90 degrees into a 3/8 in female PT thread, so the fitting screws straight onto a male stud on the machine port and the tube drops in at a right angle. Push the tube home and the stainless spring gasket and chuck grip it; press the POM release ring and it slides back out.
This sits in the resin/brass spec profile: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, and -20 to +70 C service. The D suffix here is worth knowing about: unlike PC and POC, where D only changes the release button, on PLF it changes the body colour to black, which machine builders often specify to match a dark housing or to keep fittings visually consistent across a panel. The 3/8 thread arrives with sealant already applied, so no extra tape is needed at assembly.

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 PLF L-Shaped Female Thread Adapter PLF803D Is Used
Carton-forming machine cylinder ports
A 3/8 in female elbow screws directly onto the male stud of a box-erecting machine's clamp cylinder head, letting Dia 8 mm PU tube leave vertically instead of bending sharply across the frame.
Palletizer wrist air lines
Inside the guarded wrist of a robotic palletizer, space for straight fittings is scarce; the 90 degree body turns the Dia 8 mm line along the arm while the black D-suffix housing blends with the dark robot dress pack.
Vacuum ejector feed on pick-and-place heads
The -750 mmHg vacuum rating makes PLF803D a valid feed fitting for a compact ejector on an electronics pick-and-place head, where the elbow keeps the supply tube off the PCB path.
Is the Airtac PLF L-Shaped Female Thread Adapter PLF803D the Right Part?
On the 3/8 in female thread, Dia 8 mm is the middle of the ladder: Dia 6 (PLF603) is the step down when the line feeds a smaller actuator or a flow-limited branch, and Dia 10 (PLF1003) is the step up for short trunk runs feeding several downstream drops. The bore, not the thread, sets the airflow path, so stepping the tube size changes what the line can carry even though the port stays the same.
Match the thread to the port first: 3/8 in female suits a male-stud port on a cylinder head, valve manifold or air-preparation outlet sized for it, and the sealant-coated thread means no separate sealing step. If the fitting has to pass through a sheet-metal wall instead of ending at a port, a PMF bulkhead female connector is the right shape; if the tube approach angle keeps changing, a PHF universal female elbow swivels where this fixed 90 degree body cannot. Whatever you choose, the tube OD must match exactly - a Dia 8 fitting will not seal on 5/16 in or 10 mm tube.
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 PLF L-Shaped Female Thread Adapter PLF803D FAQ
It is a one-touch female elbow for Dia 8 mm soft nylon or polyurethane tube with a 3/8 in female PT thread. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure is -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the service temperature range is -20 to +70 C. The body is PBT with a brass stud, the D suffix makes it black, and the thread ships with sealant pre-applied.
On this series it changes the body colour from the standard grey to black; the dimensions, thread, pressure rating and internal construction are identical to the grey PLF803. That is different from PC and POC straight connectors, where the D suffix alters only the release button and leaves the body grey. If your machine drawing calls out black fittings throughout the pneumatic circuit, PLF803D is the correct order code.
