About the Airtac PCF Female Thread Straight Fitting PCF401D
The AirTAC PCF401D is a PCF female one-touch connector: it joins Dia 4 mm soft nylon or polyurethane tubing to a 1/8 in PT female (internal) thread. Push the tube home and the POM chuck grips it against the stainless spring gasket for a sealed joint; press the release ring and the tube slides back out. The D suffix on the PCF series turns the whole body black, not just the button as it does on the PC and POC straight connectors.
This part follows the resin/brass one-touch profile: working pressure 0 to 1.0 MPa, proof pressure 1.5 MPa, vacuum down to -750 mmHg, and a service range of -20 to +70 C. The body is PBT with an aluminium-alloy guide and NBR O-ring seal, and the female thread arrives with sealant pre-applied, so it seals straight onto the mating male taper port without extra tape. If you need 150 C service, that is the metal BPC line, not this fitting.

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 PCF Female Thread Straight Fitting PCF401D Is Used
Electronics pick-and-place head
Feeding a compact pneumatic gripper on an SMT placement machine: the 1/8 in female thread screws onto the gripper stud while the Dia 4 PU line routes through the moving head without couplings.
Bench-top pipetting station
Connecting a Dia 4 nylon line to the 1/8 in female port of a small valve manifold in laboratory liquid-handling equipment, where the push-in joint can be opened for cleaning between protocols.
Label applicator air assist
Running Dia 4 tubing from the applicator's 1/8 in female solenoid port to the blast nozzle that seats labels on cartons, letting operators swap tubes in seconds during format changes.
Is the Airtac PCF Female Thread Straight Fitting PCF401D the Right Part?
Dia 4 is the smallest tube size the PCF series is made in; there is no 3.2 mm mini in this prefix, so the only step is up to Dia 6 (PCF601D), which gains bore headroom for lines feeding small actuators. On the thread side, 1/8 in is the bottom of the ladder; PCF402D gives the same Dia 4 tube on a 1/4 in female port for larger valve manifolds. Choose a female connector when the machine already supplies a male stud or the port itself is internal-threaded. Remember the tube OD must match exactly: a Dia 4 chuck will not hold 5/32 in imperial tube or any other size.
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 PCF Female Thread Straight Fitting PCF401D FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), proof pressure 1.5 MPa, vacuum capability to -750 mmHg (10 Torr), and a temperature range of -20 to +70 C. It takes Dia 4 mm soft nylon or polyurethane tube and carries a 1/8 in PT female thread with sealant pre-applied.
No. The chuck is sized for exactly Dia 4 mm metric tube; the imperial N-series is a separate catalogue and its tube will not seal here. This catalogue documents PT threads only, so on a 1/4 in female port order the PCF402D instead of adapting this one.
