About the Airtac PCF Female Thread Straight Fitting PCF604
The PCF604 is an AirTAC PCF female connector, a one-touch fitting that joins Dia 6 mm soft nylon or polyurethane tubing to a 1/2in PT female thread. Push the tube home and the chuck grips it while the stainless spring gasket seals against its outside diameter; press the POM release ring and the tube slides straight back out. The female taper screws directly onto a male 1/2in PT port, so no adapter nipple is needed between the port and the fitting.
This is the resin one-touch profile: 0 to 1.0 MPa working pressure, -750 mmHg vacuum capability, 1.5 MPa proof pressure and -20 to +70 C service. The body is PBT and the release button and chuck are POM, keeping the fitting light even on a port as large as 1/2in. Threads arrive with sealant already applied.

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 PCF604 Is Used
Large-port valve takeoffs
On a 5/2 solenoid valve with 1/2in PT outlet ports, PCF604 converts each outlet to push-in Dia 6 mm tubing, feeding a small gripper or clamp cylinder without an intermediate reducer block.
Welding fixture retrofits
Automotive fixture manifolds often carry 1/2in PT ports from an older build standard. Screwing in a PCF604 turns each one into a quick-drop point for Dia 6 mm lines running to swing clamps and part-presence actuators.
Panel air headers
Where an air-preparation unit or header block in a control cabinet is tapped 1/2in PT at the wall, this female connector lets 6 mm tube run directly to the solenoid bank, cutting out adapter nipples and leak points.
Is the Airtac PCF Female Thread Straight Fitting PCF604 the Right Part?
Down one thread step, PCF602 keeps the same Dia 6 mm bore on a 1/4in PT female port for compact valve and manifold outlets, with PCF603 covering the 3/8in step between them. Going the other way, PCF804 holds the 1/2in thread but widens the tube bore to Dia 8 mm, which suits a 1/2in port feeding a longer or more demanding branch. There is no female thread above 1/2in in this catalogue, so PCF604 sits at the top of the PCF thread ladder for this bore.
Remember that the 6 mm bore, not the 1/2in thread, sets the air capacity of the branch, so oversizing the port alone gains nothing. Tube OD must match exactly: a Dia 6 fitting will not hold 1/4in (6.35 mm) hose, even though the two sizes look close.
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 PCF604 FAQ
Working pressure 0 to 1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg, proof pressure 1.5 MPa and operating temperature -20 to +70 C. The fitting takes Dia 6 mm soft nylon or polyurethane tube on a 1/2in PT female thread.
No. Dia 6 mm and 1/4in (6.35 mm) differ enough that the chuck cannot seal reliably on the wrong diameter, so always use the exact matching tube. Also note that PT is the only thread standard documented for this catalogue; a G or NPT port needs its own adapter rather than a thread-variant part.
