About the Airtac PCF Female Thread Straight Fitting PCF801D
The PCF801D is an AirTAC PCF female connector from the resin one-touch family, joining Dia 8 soft nylon or polyurethane tube to a 1/8in PT female thread. Push the tube into the chuck and the stainless spring gasket grips it for a pressure-tight seal; press the POM release ring and the tube slides straight back out. The D suffix gives this version a black body instead of the standard grey, which suits machines where grey hardware disappears against painted panels.
This is the resin and brass spec profile, not the metal 0.9 MPa 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. The body is moulded from PBT with a brass stud on the male side of the part, so unlike the PC male connector there is no machined brass body here. Female PT threads arrive ready to seal onto a male stud without extra tape.

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 PCF801D Is Used
Bottle-filling machine valve island
A black Dia 8 female connector drops straight onto the male stud of a pilot valve block, so an 8mm nylon drop line is swapped in seconds during changeover without rebuilding the manifold plumbing.
Pick-and-place gripper feed
Robotic grippers often carry a female port on the body; the PCF801D threads on directly and takes an 8mm polyurethane line into a cable chain, where repeated flexing makes PU the better tube choice.
Tray-sealing machine vacuum hold-down
On packaging machines that clamp trays under vacuum, the 1/8in female thread mounts on the ejector stud and the -750 mmHg negative-pressure rating covers the suction side without a separate fitting type.
Is the Airtac PCF Female Thread Straight Fitting PCF801D the Right Part?
In the PCF ladder around this SKU sits the Dia 6 version (PCF601) below and the Dia 10 version (PCF1001) above. Stepping down to Dia 6 tightens the bore and suits short pilot runs; stepping up to Dia 10 moves more air on longer lines to cylinders and actuators. Whichever you choose, tube OD must match exactly - this Dia 8 socket will not grip Dia 6 or Dia 10 tube, and 5/16in imperial tube is not part of this catalogue at all.
Pick a female connector when the port you are fitting already carries a male stud, a gauge stem or a machined boss; the internal PT thread does the sealing. If that port points sideways inside a tight guard, a PL male elbow saves a bend in the tube instead. For passing through a cabinet wall, PMF bulkhead is the shape you want, not this one.
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 PCF801D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg, proof pressure 1.5 MPa, and a temperature range of -20 to +70 C. This SKU joins Dia 8 soft nylon or polyurethane tube to a 1/8in PT female thread and comes in the black D-body finish. AirTAC publishes flow for this family as a characteristic curve only, so capacity should be judged from the 8mm bore.
No. The spring gasket chuck is machined for one OD, so the PCF801D only holds exactly 8mm tube; tape, sleeves or reducers inside the socket will leak or blow off. Different diameters are handled by the PG or PEG reducer family instead. Also keep the tube itself within limits: soft nylon or polyurethane only, and at the top of the -20 to +70 C range it is the tube, not the fitting, that gives way first.
