About the Airtac PCF Female Thread Straight Fitting PCF804D
The PCF804D is an AirTAC PCF series one-touch female connector: a straight fitting whose Dia 8 mm tube end accepts soft nylon or polyurethane tubing push-to-connect, and whose 1/2in internal PT thread screws over a male port stud. Push the tube home and the stainless spring gasket plus POM chuck grip the OD for a seal under vacuum and pressure; press the POM release ring and the tube frees. The D suffix gives the whole body in black rather than the standard grey, and the female thread is supplied plain - the sealing sealant comes on the male stud it mates with.
This is the resin/brass spec profile, not the metal BP line: 0-1.0 MPa (0-10 kgf/cm2) working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C. Construction is a PBT threaded body on a brass stud with an aluminium-alloy guide, stainless spring gasket and NBR O-ring. Every thread in this catalogue is PT.

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 PCF804D Is Used
Packaging machine valve manifold
Screws onto a 1/2in male manifold stud on a packaging machine's valve island and hands off a Dia 8 drop line to a box-eject cylinder, keeping the connection serviceable from outside the frame.
Bottling line gate cylinder
A bottle-gate or stopper cylinder on a bottling conveyor with a 1/2in female port takes this connector directly, feeding the Dia 8 tubing that runs back along the guard to the FRL.
Pneumatic distribution on a control panel
Mounted on a machine's pneumatic distribution block, the 1/2in internal thread lands on the block's studs while the black body stays unobtrusive against a painted panel.
Is the Airtac PCF Female Thread Straight Fitting PCF804D the Right Part?
At the same 1/2in internal thread, the tube ladder steps are PCF604 below on Dia 6 and PCF1004 and PCF1204 above on Dia 10 and Dia 12 - each step changes the bore of the circuit you can feed, with Dia 10 and 12 the sizes that suit longer runs and larger actuators. Holding tube size but stepping the port down in thread gives PCF803 at 3/8in. Whatever you choose, the tube OD must match the fitting exactly: a Dia 8 PCF will not hold 1/4in or 5/16in hose, and only soft nylon or polyurethane tube is approved - semi-hard nylon will not seal on the gasket.
Match the 1/2in internal thread to a male PT port with sealant already applied; do not add tape over factory sealant. If your panel entry needs a locknut through a wall, the bulkhead family instead uses an M16x1 locknut at Dia 8, so a PMF or BPM part may fit the hole better than this connector.
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 PCF804D FAQ
It is a PCF one-touch female connector for Dia 8 mm tubing with a 1/2in internal PT thread, black (D) body. 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. Approved tubing is soft nylon or polyurethane.
Vacuum is fine - the NBR O-ring and stainless spring gasket hold -750 mmHg (10 Torr) as well as positive pressure. But the tube OD must be exactly Dia 8 mm: the chuck and gasket are machined for that OD alone, so 1/4in or 5/16in tube will neither seat nor seal. For Dia 6 or Dia 10 circuits, order the PCF604 or PCF1004 at the same thread instead.
