About the Airtac PCF Female Thread Straight Fitting PCF604D
The PCF604D is an AirTAC PCF female connector, the straight one-touch fitting with an internal thread. Its 6 mm chuck grips 6 mm outside diameter soft nylon or polyurethane tube, while the 1/2in PT female thread screws straight onto a male stud or machined port. Push the tube home and the stainless spring gasket and POM chuck clamp it; press the release ring and it slides free again.
This is the standard resin and brass line, not the metal BP family: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a working temperature of -20 to +70 C. The D suffix makes the whole body black on the PCF series, unlike PC or POC where it only colours the button. The internal PBT threaded body sits on a brass stud, and the NBR O-ring seals the collet every time the tube is re-inserted.

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 PCF604D Is Used
Actuated valve inlet on a dosing skid
The 1/2in PT female thread screws directly onto the pilot or supply port of an actuated ball valve on a chemical dosing skid, putting 6 mm tubing to the solenoid without a male nipple in between.
Regulator drop on a tray-sealing machine
Downstream of the FRL on a food tray-sealer, the female port picks up the regulator outlet stud and hands off to 6 mm polyurethane line running to the sealing-bar cylinders.
Panel-mounted air distribution block
On a machine control panel fed by a distribution manifold with tapped female ports, the PCF604D turns each 1/2in outlet into a push-in take-off for 6 mm branch lines.
Is the Airtac PCF Female Thread Straight Fitting PCF604D the Right Part?
In the PCF ladder, this 6 mm / 1/2in pairing sits near the top of the range. Stepping down, 4 mm tube uses the same large female port but halves the bore, so use it only where flow demand is small; 8 mm is the next size up if the circuit feeds a larger cylinder or a long run where pressure drop matters. On the thread side, 3/8in (PCF 603) is the step below, and 1/2in is the largest port the series offers - there is nothing above it, so plan manifolds around that ceiling.
A PCF female connector is the right answer when the receiving port is already a female thread, such as the tapped inlet of a valve island or a control-panel coupling. For male studs choose the PC series instead. Tube outside diameter must match exactly - a Dia 6 fitting will not seal on 1/4in (6.35 mm) tube, even though the numbers 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 PCF604D 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 working temperature of -20 to +70 C. The fitting accepts 6 mm outside diameter soft nylon or polyurethane tube and carries a 1/2in PT female thread. It belongs to the resin and brass one-touch line, so it is rated 0.1 MPa higher in pressure and 80 C lower in temperature than AirTAC's metal BPC family.
No preparation is required: AirTAC ships its threaded one-touch fittings with sealant already applied to the thread, so the 1/2in PT female port seals as delivered. Because the thread is internal, the fitting seals against a male stud on the equipment side - check that the mating stud is undamaged and the correct 1/2in PT size. On the tube side, simply cut the 6 mm hose square, push it fully home until it stops, and the chuck locks it; a light tug confirms the grip before you pressurise.
