About the Airtac PCF Female Thread Straight Fitting PCF803D
The PCF803D is an AirTAC PCF female connector: a one-touch fitting with an internal 3/8in PT thread at one end and a Dia 8 mm push-in socket at the other. Push the nylon or polyurethane tube home and the POM chuck grips it against the stainless spring gasket; press the release ring and the tube slides straight back out. The D suffix makes this the black version - and on the PCF family that means the whole body, not just the release button as it does on the PC and POC straights.
This part belongs to AirTAC's resin and brass one-touch line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg, proof pressure 1.5 MPa, and a service temperature of -20 to +70 C. Because the thread here is internal, sealing happens on the male taper thread you screw it onto - and as a useful contrast, the M5 sizes elsewhere in this range seal with a captive gasket instead of a taper.

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 PCF803D Is Used
Solenoid valve outlet on a machine manifold
Screws directly onto the 3/8in male PT exhaust or outlet port of a valve island, giving a single Dia 8 push-in point for the line feeding a downstream cylinder.
Paint and finishing shop supply drops
The black D body suits coating booths where grey polymer fittings stand out against dark machine frames; the female thread lands on the male drop pipe stub.
Control cabinet air take-off
Mounted on a male stud passing through a cabinet plate, the PCF803D lets a Dia 8 tube run to a pneumatic sensor or air knife without tools inside the enclosure.
Is the Airtac PCF Female Thread Straight Fitting PCF803D the Right Part?
On the thread side, PCF802 steps you down to 1/4in female and PCF804 steps you up to 1/2in female; keep the same Dia 8 tube socket either way. On the tube side at this 3/8in thread, PCF603 drops to a Dia 6 bore and PCF1003 rises to Dia 10 - the larger bore moves more air per unit of restriction, while the smaller one suits lighter actuators. If your run needs to turn at the port, the PLF female elbow is the shape to reach for instead, and the PMF bulkhead female connector is the right answer when the thread has to sit behind a panel wall.
Tube OD must match exactly: a Dia 8 PCF socket will not hold 1/4in (6.35 mm) imperial tube, even though the difference looks trivial on a ruler.
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 PCF803D FAQ
It is a female one-touch connector joining Dia 8 mm tube to a 3/8in PT internal thread, in the black D colourway. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure is -750 mmHg, proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. It takes soft nylon or polyurethane tube only.
The PCF803D's 3/8in thread is internal, so the seal is made on the male taper thread it mates with - the male component is the one that arrives with sealant pre-applied in this catalogue. Just hand-tighten plus a small turn, and do not over-torque the brass body into a steel port.
