About the Airtac PC Threaded Straight Connector PC6M5D
The PC6M5D is an AirTAC PC male one-touch connector in the D (black button) finish. It grips Dia 6 mm soft nylon or polyurethane tubing and screws into an M5x0.8 male port. Push the tube firmly home and the stainless spring gasket with NBR O-ring assembly inside the chuck clamps it for immediate pressure; press the POM release ring and the tube slides free. As a resin-series part it is rated 0-1.0 MPa working pressure, handles -750 mmHg vacuum, proves at 1.5 MPa and works from -20 to +70 C.
Two details worth knowing before you order. On the PC series the D suffix changes only the release button - the body stays the standard grey brass, unlike series where D recolours the whole part. And the M5x0.8 port seals with a small gasket rather than thread sealant, so over-tightening buys you nothing: hand-tight plus a light snug is the whole job.

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 PC Threaded Straight Connector PC6M5D Is Used
Pilot port on a compact valve manifold
M5x0.8 is the standard small port on compact pneumatic valves; the PC6M5D turns that port into an instant Dia 6 mm tube drop with a gasket-sealed thread and no sealant mess on a clean manifold.
Pressure switch and sensor hook-up
Instrument ports on switches and transducers are frequently M5. The 6 mm bore carries the tiny sensing airflow these devices need, and the black release button gives a clear visual cue on a crowded gauge panel.
Small pick-and-place gripper supply
Miniature grippers and vacuum ejectors on electronics assembly heads take M5 ports; a Dia 6 mm line keeps the supply light and flexible while the one-touch chuck survives the constant handling of a moving gantry.
Is the Airtac PC Threaded Straight Connector PC6M5D the Right Part?
On the PC ladder with an M5 thread only two tube sizes exist: Dia 4 and Dia 6. The step down is PC4M5 for 4 mm lines feeding light pilot or signal circuits; there is no step up - Dia 6 is the largest tube any PC fitting takes on M5. If your line grows to Dia 8 or 10 you move to a 1/8-inch port such as PC801 or PC1001, because M5 simply is not offered above Dia 6 on this series.
Match the thread to the port, not the other way round: M5x0.8 is the small metric port found on compact valves, switches and manifolds. And remember the bore rule - a Dia 6 one-touch chuck holds exactly 6 mm OD metric tube and will not grip 1/4-inch (6.35 mm) tubing, even though the two look close.
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 PC Threaded Straight Connector PC6M5D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. It accepts Dia 6 mm soft nylon or polyurethane tubing on an M5x0.8 male thread; the D suffix means a black release button on the standard grey body.
Unlike the larger PT threads in this catalogue, which arrive with sealant, the M5x0.8 size seals with a small gasket. Thread the fitting in by hand, then snug it gently - it needs far less torque than a 1/8-inch fitting, and forcing it can crush the gasket seat rather than improve the seal.
