About the Airtac PCF Female Thread Straight Fitting PCF402D
The PCF402D is an AirTAC PCF female elbow from the one-touch fitting family: an internally threaded 1/4 in PT port on one leg and a Dia 4 mm tube socket on the other, set at 90 degrees. Push the soft nylon or polyurethane tube straight into the chuck and the stainless spring gasket locks it against the guide; press the POM release ring and the tube slides straight back out. The female thread means you bolt the fitting onto a male stud or plug, so the fitting itself becomes the corner in the circuit.
This sits on the standard resin and brass spec profile, not the high-temperature metal line: working pressure 0-1.0 MPa, vacuum down to -750 mmHg, proof pressure 1.5 MPa, and a service range of -20 to +70 C. Because of the D suffix the PBT body arrives in black rather than the standard grey - on the PCF family the colour change applies to the body, not just the release button as it does on PC and POC straight connectors. The 1/4 in thread comes with sealant already applied; only the M5 sizes in this catalogue use a sealing gasket instead.

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 PCF402D Is Used
Solenoid valve outlet on a manifold
A 5/2 valve bank with 1/4 in male outlet studs takes the PCF402D directly, turning the airline 90 degrees into Dia 4 mm tubing without an extra nipple-and-Elbow stack to leak.
Small pneumatic press cylinder
Compact bore cylinders on bench presses and clamping fixtures often have the port facing the operator; the female elbow points the 4 mm line down along the cylinder barrel, out of the pinch zone.
Rear-of-panel wiring in an inspection machine
Vision and test rigs with black anodised panels suit the black D-suffix body; the 90 degree exit keeps Dia 4 mm drops to sensors and mini grippers tight against the frame.
Is the Airtac PCF Female Thread Straight Fitting PCF402D the Right Part?
Dia 4 mm is the smallest tube bore AirTAC makes in this family, so the only step from here is up: Dia 6 (a PCF602-style part) buys you a noticeably larger bore and better flow headroom for the same 1/4 in port. Stay at Dia 4 when the actuator or sensor it feeds is genuinely a 4 mm port; do not buy it hoping a 6 mm tube will squeeze in. The thread side is fixed at 1/4 in PT female, which mates directly with the male studs common on solenoid valve outlets and cylinder ports. One thing the code cannot tell you: tubing OD must match the socket exactly - a Dia 4 chuck will not grip 1/4 in (6.35 mm) imperial tube, and no O-ring will rescue it.
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 PCF402D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature range -20 to +70 C. Size: Dia 4 mm tube socket on a 1/4 in PT female thread, with sealant pre-applied. Tubing must be soft nylon or polyurethane. These are the standard resin/brass one-touch ratings; the D suffix changes colour only, never the figures.
No. The D suffix on the PCF family changes the body colour from grey to black and nothing else - the same PBT body, brass stud, POM chuck and button, and identical dimensions and pressure ratings. Buyers choose black for cosmetic matching on dark machine frames and control panels; grey buyers get the same part in a different colour.
