About the Airtac PLF L-Shaped Female Thread Adapter PLF601
The PLF601 is an AirTAC PLF female elbow from the resin one-touch family: a 90 degree fitting that pushes Dia 6 mm soft nylon or polyurethane tubing into one end and presents a 1/8in PT INTERNAL (female) thread on the other. Because the thread is internal, the fitting bolts down over a male stud port instead of screwing into a tapped hole - the machine side supplies the male thread, the fitting supplies the seal. To connect, push the tube straight in until it bottoms; the stainless spring gasket and chuck grip the OD, and the POM release ring frees the tube again when you push it in and press the ring.
This is the standard resin/brass profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg, proof pressure 1.5 MPa, and a temperature window of -20 to +70 C. The grey PBT body carries a brass stud that arrives with sealant already on the thread, the chuck and release button are POM, and the O-ring is NBR.

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 PLF601 Is Used
Pick-and-place gripper port
A small pneumatic gripper on a robot end-of-arm usually has a male stud port facing sideways. The PLF601 bolts straight onto the stud and turns the 6mm supply line 90 degrees away from the gripper jaws, so the tube clears the wrist as it rotates.
Valve manifold pilot take-off
On a compact solenoid valve manifold, the 1/8in pilot port often sits a few millimetres from the adjacent valve body. A female elbow seats flush against the port face and points the tubing away, where a straight connector would foul the next valve.
Packaging machine guard routing
Inside the sheet-metal guard of a form-fill-seal machine, cylinder ports sit close to the guard wall. Bolting the PLF601 onto the male stud and dropping a 6mm run downward keeps the tube inside the guarded envelope and away from the sealing jaw heater.
Is the Airtac PLF L-Shaped Female Thread Adapter PLF601 the Right Part?
On the PLF ladder for a 1/8in female thread, the neighbouring tube sizes are Dia 4 (PLF401) below and Dia 8 (PLF801) above. Stepping down to Dia 4 gives you a slimmer, more flexible run for light pilot lines and small actuators; stepping up to Dia 8 buys more effective bore for shorter cylinder fill times on larger actuators. For this Dia 6 size the PLF thread ladder also runs M5, 1/4in, 3/8in and 1/2in, so you can upsize the port without changing the tube.
Choose an elbow over a straight connector when the tube must turn out of the port face, because a 90 degree body shortens the straight run you need and keeps the tube off hot or moving machine parts. The elbow also removes the sharp side-load a bent tube would put on a straight fitting. One caution: Dia 6 means 6.0 mm OD. It is NOT 1/4in tube (6.35 mm OD) - a Dia 6 chuck will not seal 1/4in tubing and vice versa, so match the tube exactly.
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 PLF601 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 6 mm tube OD with a 1/8in PT female thread. It is a resin one-touch fitting with a PBT body on a brass stud, suitable for soft nylon or polyurethane tubing only.
The 1/8in PT port on the PLF601 is internal, so your machine port must have a male stud thread. Screw the fitting onto the stud with a spanner on the body flats; the stud arrives with thread sealant applied, so no extra tape or paste is needed. Hand-start the thread first to avoid cross-threading, and do not hold the plastic body while torquing the tube side.
