About the Airtac PCF Female Thread Straight Fitting PCF4M5
The PCF4M5 is an AirTAC PCF female connector, a resin one-touch fitting that terminates Dia 4 mm soft nylon or polyurethane tubing in an M5x0.8 internal thread. Where the PC range offers a male stud, the PCF body is tapped female, so it screws onto a male M5 stud or ported block instead of into a tapped hole. Push the tube home and the stainless chuck inside the chuck grips it against the spring gasket; press the POM release ring and the tube slides straight back out.
This is the resin/brass spec profile: 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 chuck, guide and O-ring are POM, aluminium alloy and NBR respectively, with a brass stud behind the thread. One detail worth knowing before you fit it: M5 versions arrive with a sealing gasket on the thread, not pre-applied sealant, so the gasket does the sealing against the port face and nothing needs curing.

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 PCF4M5 Is Used
Mini valve island pilot ports
Compact pneumatic valve islands and solenoid pilots frequently carry M5 studs on their exhaust and pilot faces. PCF4M5 threads directly onto those studs, letting Dia 4 tubing run the pilot signal to a small actuator without an adapter spacer.
Lab analyser sample lines
Benchtop analysers, dosing heads and small vacuum pick-up tools built around M5 instrument ports take Dia 4 polyurethane tubing cleanly through this fitting. The -750 mmHg vacuum rating covers light suction and sample-draw duties on the resin line.
Small gripper on a compact robot arm
A miniature parallel gripper with an M5 air inlet, mounted where an elbow will not fit, takes PCF4M5 straight on. The straight female body keeps the run short and the Dia 4 bore matches the gripper's small air demand.
Is the Airtac PCF Female Thread Straight Fitting PCF4M5 the Right Part?
On the M5 thread this fitting sits at the bottom of the ladder: M5 is offered in Dia 4 and Dia 6 only, so PCF4M5 is the smallest M5 option and the step up is PCF6M5, which buys you a 50% larger bore for circuits where the Dia 4 tube itself is the bottleneck. If you need to keep Dia 4 tube but your port is larger, the Dia 4 tube size also exists on 1/8 in and 1/4 in threads (PCF401, PCF402). Match the thread form to the hardware: female PCF suits a male stud, a barbed adapter or a threaded instrument port; if your port is already tapped, you want the male PC instead.
Tube OD must match exactly. A Dia 4 chuck will not seal on 5/32 in or any other near-miss size, and forcing it is the most common cause of a one-touch leak on commissioning day.
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 PCF4M5 FAQ
Tube size Dia 4 mm, thread M5x0.8 female. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg, proof pressure 1.5 MPa, temperature -20 to +70 C. It accepts soft nylon or polyurethane tubing only, releases via the POM push ring, and the M5 thread seals through a supplied gasket rather than applied sealant.
No. AirTAC supplies M5 sizes with a sealing gasket fitted to the thread, which seals against the mating port face as you tighten by hand-plus-a-fraction; larger threaded sizes in this range arrive with sealant pre-applied instead. Fit soft nylon or polyurethane tube of exactly Dia 4 mm, push it firmly home until it bottoms, and tug it to confirm the chuck has locked before pressurising.
