About the Airtac PCF Female Thread Straight Fitting PCF6M5
The PCF6M5 is an AirTAC PCF female connector from the resin one-touch range. Its internal M5x0.8 thread screws over a male stud or port, while the Dia 6 mm outlet grips soft nylon or polyurethane tubing. Push the tube in and the stainless spring gasket with POM chuck clamps it; press the release ring and it slides straight back out.
This is the standard resin/brass profile, so it carries 0-1.0 MPa working pressure, 1.5 MPa proof pressure, -750 mmHg (10 Torr) vacuum and a -20 to +70 C window. Because the thread is M5, it seals with a small sealing gasket rather than the pre-applied thread sealant AirTAC puts on the 1/8 inch and larger sizes - a detail worth knowing before you wrap any thread tape on it. The body here is PBT over a brass stud; grey is standard, and unlike the PC/POC straights a D suffix on this series changes the whole body to black, not just the button.

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 PCF6M5 Is Used
Valve manifold pilot ports
M5 threaded pilot and exhaust ports are common on compact valve manifolds in packaging machines. The PCF6M5 screws directly over the male stud and hands off a clean 6 mm line to the actuator.
Analytical instrument pneumatics
Sample transport and reagent lines in laboratory analysers run on 6 mm PU tubing with tiny M5 ports. A female body with a gasket seal avoids thread tape shedding particles into the fluid path.
Small pick-and-place gantries
Miniature grippers and vacuum ejector blocks on 3-axis gantry modules often expose M5 male fittings. The PCF6M5 turns each stud into a push-in 6 mm connection without adding adapter elbows.
Is the Airtac PCF Female Thread Straight Fitting PCF6M5 the Right Part?
M5 on the PCF ladder supports only Dia 4 and Dia 6 tube, so this is the top of the M5 ladder - there is no PCF8M5 to step up to. The next step is PCF4M5 below for 4 mm tubing, or PCF601 above, which moves you to a 1/8 inch female thread while keeping the same 6 mm bore. Stepping to PCF601 buys you a physically stronger thread and easier wrench access; staying on M5 keeps the port footprint at its smallest.
Match the internal M5x0.8 thread to the male stud it rides on - M5 and 1/8 inch are not interchangeable despite looking similar at a glance. And remember tube OD must match exactly: a Dia 6 fitting will not seal on 1/4 inch or 8 mm tube. If your port is on the far side of a panel or you need a 90 degree turn, look at PMF or PLF instead of a straight female body.
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 PCF6M5 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, negative pressure -750 mmHg (10 Torr), temperature -20 to +70 C. It joins Dia 6 mm soft nylon or polyurethane tube to an M5x0.8 female thread, sealed by a gasket. Thread standard on the larger sizes of this catalogue is PT.
No. M5 sizes in this range seal with a dedicated sealing gasket, so the pre-applied sealant used on the 1/8 inch and larger threads is not involved. Adding tape to an M5 can distort the gasket seat and cause leaks, so fit it dry against the gasket and check for hold.
