About the Airtac PLF L-Shaped Female Thread Adapter PLF804
The PLF804 is an AirTAC PLF female elbow from the resin and brass one-touch range. It terminates 8 mm OD soft nylon or polyurethane tube into a 1/4 in PT female thread, turning the air path 90 degrees so the tube leaves sideways rather than over the top of the port. Because the thread is female, it screws onto a male stud or nipple you already have on the machine - the opposite logic to the PC male connector, which screws into a female port.
Connection is a genuine one-touch action: push the 8 mm tube square into the chuck until it bottoms, and the stainless spring gasket and POM chuck grip it against the NBR O-ring; press the release ring and the tube frees. This is the resin profile, not the metal BP line: 0-1.0 MPa working pressure (0-10 kgf/cm2), -750 mmHg vacuum, 1.5 MPa proof pressure, and -20 to +70 C. The body is PBT over a brass thread housing, and the PT thread leaves the factory with sealant already applied, so it seals straight onto a clean male taper.

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 PLF804 Is Used
Valve manifold branch turns
On a packaging machine solenoid manifold, the PLF804 screws onto a 1/4 in male stud outlet and takes the 8 mm drop line off at a right angle, keeping the tube run flat along the manifold face instead of standing proud where a guard or cable tray would foul it.
Elbow at a guarded cylinder port
Where a 8 mm-fed pneumatic cylinder sits inside a sheet-metal guard with the port facing a wall, the female elbow bolts onto a male stud adapter and turns the feed sideways, so the tube can be routed along the machine frame rather than bent sharply at the port.
Vacuum pick-and-place drop
Rated to -750 mmHg as well as pressure, the PLF804 suits the 8 mm vacuum line from an ejector down to a small suction cup on a robotics end-of-arm tool, where the elbow keeps the cup feed low-profile between the gripper fingers.
Is the Airtac PLF L-Shaped Female Thread Adapter PLF804 the Right Part?
Step down to PLF602 for 6 mm tube or up to PLF1004 for 10 mm tube, both on the same 1/4 in female thread. The bigger the bore, the less the fitting throttles the branch and the lower the pressure drop to the actuator - pick 8 mm when the cylinder or valve port is already served by 8 mm tube. For the female-threaded version in other bores, the PLF ladder runs 4, 6, 8, 10 and 12 mm.
Match the thread to the port first: 1/4 in PT female is right when the machine offers a male taper stud or a male-threaded adapter; if the port is itself female, a PC-series male connector is the cleaner answer. And the tube rule is absolute - the port takes 8 mm OD tube exactly. A Dia 6 fitting will not hold 8 mm tube and a Dia 8 fitting will not grip 6 mm, no matter how hard you push.
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 PLF804 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. It accepts 8 mm OD soft nylon or polyurethane tube and has a 1/4 in PT female thread. Body is PBT with a brass thread housing, POM chuck and release button, aluminium alloy guide, stainless spring gasket and NBR O-ring.
No. AirTAC ships every threaded one-touch part with sealant already applied to the PT thread, so it should seal directly onto a clean male taper stud. On a reused or damaged male thread a light wrap of PTFE tape is a sensible backup, but the factory coating is designed to be used as supplied. Do not use a thread sealant that could wick into the chuck area before the tube is inserted.
