About the Airtac PLF L-Shaped Female Thread Adapter PLF803
The PLF803 is an AirTAC PLF female elbow from the resin one-touch range: a Dia 8 mm push-in tube socket turning 90 degrees into a 3/8 in PT female thread. Because the thread is female, the fitting drops straight over a male stud on a cylinder, valve or air preparation unit, so no extra nipple is needed between port and fitting.
Connection is genuinely one-touch: push the soft nylon or polyurethane tube home and the internal chuck grips it against the stainless spring gasket and NBR O-ring; press the POM release ring and the tube slides back out. This is the standard resin spec, not the metal 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 over a brass threaded section, and the PT thread arrives factory-sealed, ready to make up.

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 PLF803 Is Used
Solenoid valve outlet on a bottling line
The 3/8 in female thread screws over the male stud of a valve manifold output, and the 90 degree elbow turns the flow sideways so an 8 mm tube run reaches the filling gripper cylinder without a loop of hose behind the valve plate.
Rotary actuator port inside a cramped guard
On a pick-and-place unit the actuator port often points straight at the machine frame. A female elbow lets the fitting sit flush on the port stud while the 8 mm tube exits at right angles, clear of the moving arm.
Cartoning machine vacuum generator feed
Vacuum ejectors on carton erecting stations are usually fed from a 3/8 in ported supply. The PLF803 carries the 8 mm supply tube down into the ejector inlet, and its 0 to 1.0 MPa rating plus -750 mmHg vacuum tolerance covers both the supply and the ejector side.
Is the Airtac PLF L-Shaped Female Thread Adapter PLF803 the Right Part?
On the PLF ladder with a 3/8 in female thread, Dia 8 sits between Dia 6 (PLF603) and Dia 10 (PLF1003). Step down to 6 mm when feeding small grippers or pilot lines where flow demand is modest; step up to 10 mm when the run supplies a larger bore cylinder and you want less pressure drop along the tube. All three share the same 3/8 in port thread, so the port side of your drawing does not change.
If the port itself is 1/4 in rather than 3/8 in, the same elbow exists as PLF802. Check that the port is actually male-threaded PT; a female elbow on a female port needs a separate connector. And match the tube exactly: the Dia 8 socket holds 8 mm OD tube only and will not seal on 5/16 in or 1/4 in imperial 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 PLF803 FAQ
It is a one-touch female elbow taking Dia 8 mm soft nylon or polyurethane tube into a 3/8 in PT female thread. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure down to -750 mmHg, proof pressure 1.5 MPa, and the operating temperature range is -20 to +70 C. Standard colour is grey; the body is PBT with a brass threaded section and the thread is PT throughout.
Only if that tube is exactly 8 mm outside diameter. The chuck and gasket are sized for one OD, so 6 mm or 10 mm tube will not seal here; those sizes sit under PLF603 and PLF1003 with the same 3/8 in thread. Soft nylon and polyurethane are the approved tube materials, and above room temperature it is the tube rating, not the fitting, that sets the limit.
