About the Airtac PCF Female Thread Straight Fitting PCF801
The PCF801 is an AirTAC PCF one-touch female connector: a straight push-in fitting whose threaded side carries a 1/8in INTERNAL (female) PT thread instead of the usual male stud. On the other side it grips Dia 8 mm outside-diameter tubing. Push the tube into the chuck and the stainless spring gasket plus POM chuck lock it instantly; press the release ring and the tube slides back out. No tools, no clamps, no re-cutting the tube between releases.
This is the resin and brass profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. Use soft nylon or polyurethane tube. The PBT body carries a brass stud section, and every threaded PCF part leaves the factory with sealant already applied to the female thread, so most installs need no extra PTFE 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 PCF801 Is Used
Valve manifold outlets
A 5/2 solenoid valve sub-plate with a 1/8in male outlet takes the PCF801 directly; the female thread seats on sealant and the Dia 8 push-in side runs airline to the actuator without a separate nipple.
FRL and air-prep drops
On a packaging line, the male outlet of a filter-regulator-lubricator unit is a natural home for this fitting - hand-tighten the sealant-coated female thread, then push Dia 8 PU tube down to the point-of-use.
Pneumatic test rigs
Fixture and leak-test stations get re-plumbed often; the PCF801 lets a technician release and re-route Dia 8 nylon tubing by hand between test cycles while the female thread stays fixed to the instrument port.
Is the Airtac PCF Female Thread Straight Fitting PCF801 the Right Part?
On the tube side, PCF801 sits mid-ladder: PCF601 steps down to Dia 6 tubing for lighter lines and tighter bend radii, while PCF1001 steps up to Dia 10 where a branch feeds a larger cylinder or wants less pressure drop over a long run. On the thread side, if the mating port is 1/4in male rather than 1/8in, order PCF802 instead - same Dia 8 tube grip, bigger female thread. Match the tube exactly: a Dia 8 one-touch chuck holds only Dia 8 tube and will not seal on 5/16in or 1/4in imperial hose.
A female connector is the right answer when the machine already presents a male parallel or tapered stub - think valve manifold outlets or the male inlet on a filter-regulator unit. If you need to pass the fitting through a panel wall, that is a bulkhead job (PMF), not this part.
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 PCF801 FAQ
It is a one-touch female connector joining Dia 8 mm tube to a 1/8in female PT thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. Suitable tubing is soft nylon or polyurethane. Standard colour is grey; the D suffix gives a black release button.
No tape is normally needed: AirTAC ships the female thread with sealant already applied, and M5-size parts in this family use a sealing gasket. As for tube, the chuck geometry is size-specific - a PCF801 grips only Dia 8 mm tube, so to switch to Dia 6 or Dia 10 tubing you order the matching fitting rather than forcing a different tube into this one.
