About the Airtac PCF Female Thread Straight Fitting PCF4M5D
The PCF4M5D is an AirTAC PCF female connector, a resin one-touch fitting that joins Dia 4 mm soft nylon or polyurethane tubing to a tapped M5x0.8 port. Unlike the male PC range, the PCF presents an internal thread, so the buyer screws a matching male M5 stud or bolt through it into the equipment port. The D suffix gives this series a black body, a practical choice where grey fittings would clash with dark machine housings or control panels.
Installation takes seconds: push the 4 mm tube squarely into the collet until it bottoms out, and the stainless spring gasket and POM chuck lock it against an NBR O-ring seal; press the release ring to free it again. This resin profile is rated 0-1.0 MPa (0-10 kgf/cm2) working pressure, withstands 1.5 MPa proof pressure, handles -750 mmHg (10 Torr) vacuum and works from -20 to +70 C. One detail worth knowing: because the thread is M5, the joint seals with a supplied sealing gasket rather than the pre-applied sealant used on the larger threaded sizes.

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 PCF4M5D Is Used
Compact cylinder port take-off
Small-bore AirTAC and ISO 6432 style cylinders often carry only a tapped M5 port. This female connector lets an M5 male stud pass through it, putting a Dia 4 supply line on a tight actuator without adapters.
Vacuum ejector pick-and-place
The -750 mmHg vacuum rating suits Dia 4 polyurethane runs feeding compact ejectors on electronics pick-and-place heads, where the black body keeps the end-of-arm tooling visually clean.
Pilot signal lines on small valves
Pilot ports on compact solenoid valves are commonly M5 tapped. The 4 mm bore carries a low-volume pilot signal precisely, and the push-fit end means a solenoid swap takes seconds.
Is the Airtac PCF Female Thread Straight Fitting PCF4M5D the Right Part?
Dia 4 mm is the smallest tube size this standard PCF line takes - the 3.2 mm size is reserved for the mini PC and PL -M series, so this is the floor of the ladder. Stepping up to a PCF6M5 buys you a Dia 6 bore, which moves noticeably more air to a cylinder or ejector; the trade is a larger button and body envelope. On the thread side, M5 is the entry point; the next step is a 1/8 in version, which swaps the gasket seal for a sealant-coated tapered PT thread.
Match the M5x0.8 pitch carefully - forcing this fitting onto a 10/32 or M6 port strips the gasket seat. And remember that one-touch collets grip one diameter only: a Dia 4 fitting will not hold 5/32 in or 1/4 in tube, however close it looks.
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 PCF4M5D FAQ
It is a PCF female one-touch connector taking Dia 4 mm soft nylon or polyurethane tube on one side and an M5x0.8 internal thread on the other. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, negative pressure -750 mmHg (10 Torr), and operating temperature -20 to +70 C. The chuck and release button are POM, the guide aluminium alloy, the spring gasket stainless and the O-ring NBR. The D suffix makes the body black, and the thread is sealed by a gasket, not sealant.
The larger PCF sizes (1/8 in and up) arrive with sealant pre-applied to their tapered PT threads, but an M5x0.8 port is too small for that system. AirTAC therefore seals the M5 joint with a sealing gasket supplied with the fitting. Do not add tape or paste to the M5 thread - the gasket does the sealing, and extra compound can foul the fine pitch.
