About the Airtac PLF L-Shaped Female Thread Adapter PLF402
The PLF402 is an AirTAC PLF female elbow, a one-touch fitting that joins Dia 4 mm soft nylon or polyurethane tubing to a 1/4in PT female threaded port. The internal thread lets you screw the fitting onto a male stud or nipple with a spanner, while the elbow body turns the tube run through 90 degrees so the hose leaves sideways instead of standing proud of the port.
Connection is tool-free on the tube side: push the Dia 4 tube fully home and the stainless spring gasket and chuck inside the chuck assembly grip it for a sealed joint; press the POM release ring and the tube slides straight back out. This is the resin/brass profile, not the metal BP line: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, and a service window of -20 to +70 C. The threaded body is PBT over a brass stud and arrives with sealant already applied to the thread, 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 PLF402 Is Used
Packaging machine sealing head
Feeding a small pneumatic cylinder on a carton sealing head where the 90 degree female elbow keeps the 4 mm tube flat against the bracket instead of fouling the moving jaw.
Pick-and-place gantry port
Connecting the pilot or actuator line on a gantry pick-and-place unit, where the internal 1/4in thread screws directly onto the male stud of a compact guided cylinder.
Lab vacuum transfer line
Routing a low-vacuum transfer line on a benchtop analyser: the fitting holds -750 mmHg (10 Torr), so a small vacuum draw through 4 mm polyurethane tube is within its rated window.
Is the Airtac PLF L-Shaped Female Thread Adapter PLF402 the Right Part?
Dia 4 is the smallest tube size this series is made in, so there is no size below it; the next step up is Dia 6, which gains bore for airflow on the same 1/4in port and suits runs feeding larger cylinders. On the thread side, 1/8in is the size below and 3/8in the size above, so check the male stud on your component before ordering. A female elbow is the right answer where the port is a male stud on a cylinder, valve or manifold and a straight connector would project into a guard or clash with a nearby hose.
Tube OD must match exactly: a Dia 4 fitting will not grip 6 mm tube, and it will not hold 1/4in (6.35 mm) hose either - the 1/4in in this part number describes the female thread only.
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 PLF402 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature range of -20 to +70 C. This SKU joins Dia 4 mm tubing to a 1/4in PT female thread. Use only soft nylon or polyurethane tube of exactly 4 mm OD.
No. The 1/4in in the part number is the female PT thread on the port side; the tube side grips only Dia 4 mm OD tubing. If your hose is 1/4in (6.35 mm) OD, it will not seal in this fitting - you need the Dia 6 size from the same series for 6 mm tube, and no imperial tube sizes are offered in this catalogue.
