About the Airtac PCF Female Thread Straight Fitting PCF804
The PCF804 is an AirTAC PCF female connector from the resin one-touch family. It joins a Dia 8 mm soft nylon or polyurethane tube directly into a 1/2in PT female tapped port, with no male stud or hex nipple needed in between. Push the tube home and the internal chuck grips it; press the POM release ring and the tube slides back out for rework.
This is the resin/brass spec profile, not the metal BPC line: working pressure 0-1.0 MPa, vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa and a temperature window of -20 to +70 C. The chuck and release button are POM, the guide is aluminium alloy, the spring gasket is stainless and the seal is an NBR O-ring. The 1/2in female thread arrives ready to install on a PT port.

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 PCF804 Is Used
Pneumatic press cylinder drop
Feed a 1/2in-ported air cylinder on a small pneumatic press or clamping fixture: the PCF804 screws into the tapped head port and takes a Dia 8 supply line straight off the manifold.
Tapped manifold branch on injection machines
Plastics and die-casting machines carry valve manifolds with pre-tapped 1/2in PT ports. A female connector bolts on without a hex nipple, keeping the branch short inside cramped manifold valving.
Rotary actuator line on bottling lines
Rack-and-pinion rotary actuators on filling and capping machines often use 1/2in female ports; the push-inDia 8 connection makes sensor-line or pilot-line routing quick to rework during changeovers.
Is the Airtac PCF Female Thread Straight Fitting PCF804 the Right Part?
Both neighbours exist on the PC family ladder. Stepping the tube down to Dia 6 (PCF604) suits lighter lines and smaller cylinder ports; stepping up to Dia 10 (PCF1004) moves meaningful volume to bigger actuators. On the thread side, 3/8in is the step down and 1/2in is the largest female port this series offers, so there is nothing above it. Check the interface table before mixing sizes: not every tube/thread pair on this series is manufactured.
The female thread is the reason to pick PCF over PC: it screws straight onto a tapped port with no external adapter, shortening the stack and removing one potential leak joint. Remember the tube OD must match exactly - a Dia 8 chuck will not seal on 1/4in (6 mm) or 5/16in (8 mm is fine, 1/4in is not) imperial tube.
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 PCF804 FAQ
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. This SKU is the Dia 8 mm tube size with a 1/2in PT female thread, from the resin one-touch PCF series.
The threaded portion arrives from AirTAC with sealant already applied, so on a clean PT tapped port it can normally be fitted as delivered. Inspect the thread on older or reused ports, and never run the fitting past its rated 1.0 MPa working pressure to test a seal.
