About the Airtac PLF L-Shaped Female Thread Adapter PLF804D
The PLF804D is an AirTAC PLF female elbow from the resin one-touch range, turning a Dia 8 mm tube through 90 degrees into a 1/2 in PT female thread. Because the thread is internal, it bolts straight onto a male stud, a threaded port or an existing screw-in nipple without adding another hex boss to the stack. The D suffix makes the PBT body black instead of the standard grey, which matters on machines where the plumbing sits behind clear guards and a neutral colour keeps the layout looking tidy.
Connection is genuinely one-touch: push the soft nylon or polyurethane tube into the chuck until it bottoms, and the stainless spring gasket and POM collet grip it against a NBR O-ring; press the POM release ring and the tube slides back out. This is the resin spec profile, so it runs 0 to 1.0 MPa (0 to 10 kgf/cm2), handles -750 mmHg (10 Torr) vacuum, carries a 1.5 MPa proof pressure and works from -20 to +70 C. The 1/2 in thread arrives with sealant already applied, and the brass stud behind the PBT body carries the load into 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 PLF L-Shaped Female Thread Adapter PLF804D Is Used
Palletiser clamp cylinders behind guards
A clamp cylinder on a palletising cell usually has its 1/2 in port facing sideways where a straight fitting would foul the guard. The PLF804D turns the Dia 8 hose down along the machine frame, and the black body disappears against painted steelwork.
Manifold-mounted valve outlets on packaging lines
Solenoid valve manifolds on form-fill-seal machines often present a male 1/2 in stud rather than a port. The internal thread of this female elbow screws directly onto that stud, then feeds an 8 mm line to the vacuum generator or ejector.
Bottle-rinse machine air wipe nozzles
Rinse tunnels run ambient air lines in warm, humid conditions within the -20 to +70 C window of this resin profile. An 8 mm elbow at each nozzle bracket keeps the drop legs tight to the conveyor side rail and releases quickly when nozzles are re-pitched.
Is the Airtac PLF L-Shaped Female Thread Adapter PLF804D the Right Part?
On the 1/2 in thread, Dia 8 sits between Dia 6 below it and Dia 10 above it. Stepping down to a Dia 6 female elbow shrinks the bore and suits lighter actuators with lower air demand; stepping up to Dia 10 buys capacity for longer runs and bigger cylinders, at the cost of a visibly larger body that needs more clearance behind the elbow. If the port itself is 3/8 in, the Dia 8 3/8 in PLF version pairs the same bore with the smaller thread instead. Whichever you pick, the tube OD must match the fitting exactly: a Dia 8 chuck will not seal on 5/16 in or 6 mm tube, and forcing a mismatch is the usual cause of slow leaks. Where the tube must approach parallel to the mounting face, a PL male elbow or a PH universal elbow is the better shape than this female pattern.
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 PLF804D FAQ
It joins a Dia 8 mm tube to a 1/2 in PT female thread. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure -750 mmHg (10 Torr), and proof pressure 1.5 MPa. The temperature range is -20 to +70 C with soft nylon or polyurethane tubing. It belongs to the resin one-touch family, not the 0.9 MPa / 150 C metal BPC line.
No. AirTAC ships this threaded resin fitting with sealant already applied to the thread, so it is ready to screw onto a male stud or port as delivered. Note that this applies to the thread only: the tube connection still relies on the one-touch chuck gripping a clean, square-cut Dia 8 tube pushed fully home.
