About the Airtac PCF Female Thread Straight Fitting PCF601D
The PCF601D is an AirTAC PCF female connector from the resin one-touch range: it screws into a male 1/8in PT port and grips a Dia 6 mm soft nylon or polyurethane tube at the other end. Push the tube home and the stainless spring gasket plus the POM chuck clamp it against the NBR O-ring; press the release ring and the tube slides straight back out. The female thread is the whole point of this variant - where a PC male connector adds another joint into the port, the PCF threads directly onto the male stub, saving height and a potential leak path.
This is the standard resin spec 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, and a service temperature of -20 to +70 C. The trailing D orders the black colour version, and on the PCF body that means the body itself is black - on PC and POC straights the D only changes the release button, so do not assume the same rule here. The 1/8in thread arrives with sealant already applied, ready to wind into the 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 PCF601D Is Used
Solenoid valve manifold outlets
Many 5/2 and 3/2 solenoid valves present a male 1/8in PT exhaust or outlet stub. The PCF601D winds straight onto it and takes 6mm polyurethane tubing to the silencer or actuator, with the factory-applied sealant doing the sealing job that loose PTFE tape often does badly on small stubs.
Vacuum pick-and-place on carton packers
Vacuum lines to suction cups on cartoning and case-packing heads commonly run at part-vacuum. This fitting holds -750 mmHg (10 Torr), and the 6mm bore keeps the cup lines compact enough to route through the moving gantry without chafing.
Machine rebuilds with mixed thread ports
When retrofitting or repairing older machinery that mixes 1/8in ports on valves with 6mm tubing runs, a female connector lets you adapt at the port itself instead of stacking a male connector plus a hex nipple - one fewer joint to leak inside a guarded area.
Is the Airtac PCF Female Thread Straight Fitting PCF601D the Right Part?
Size it in both directions. On the tube side, one step down is Dia 4 and one step up is Dia 8; stepping up doubles the bore area, so the Dia 8 variant is the one to pick when the same 1/8in port feeds a larger-bore line and you want less pressure drop along the run. On the thread side, the neighbours are M5 below and 1/4in above; M5 uses a sealing gasket instead of thread sealant and suits small valve bodies, while 1/4in gives a stiffer mechanical joint on bigger manifolds. Whichever way you go, the tube OD must match the fitting exactly - a Dia 6 PCF will not seal on 1/4in (6.35 mm) tube, even though the numbers look close.
Choose this female shape when the equipment already presents a male threaded stub, for example on a solenoid valve or a cylinder head port. If you need to pass through a panel wall instead, that is a job for the PMF bulkhead female connector, and if the tube must turn 90 degrees at the port, look at the PLF female elbow rather than adding a separate elbow fitting downstream.
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 PCF601D FAQ
Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure goes to -750 mmHg (10 Torr), and proof pressure is 1.5 MPa. The service temperature range is -20 to +70 C. This SKU joins a Dia 6 mm soft nylon or polyurethane tube to a 1/8in PT female thread, and it is the resin/brass one-touch profile - not the 0.9 MPa / 150 C metal BP line.
No. AirTAC supplies threaded one-touch fittings with sealant already applied to the thread, so the PCF601D can be wound straight onto a clean male PT port. (On M5 sizes the range uses a sealing gasket instead - a different sealing method for a different thread.) AirTAC publishes no tightening torque for these fittings, so follow normal good practice for a small tapered thread and do not over-stress the brass.
