About the Airtac PC Threaded Straight Connector PC6M5
The PC6M5 is an AirTAC PC male connector, the straight push-to-connect fitting that screws into a female port and grips a Dia 6 mm tube on its outlet. The M5x0.8 male stud threads into the port, and on M5 sizes the sealing is done by a captive gasket rather than pre-applied thread sealant, so the joint seals on the small machined face without compound working loose in a tight cavity. The stud body is brass with a PBT head, finished grey.
To connect, push the 6 mm soft nylon or polyurethane tube straight home into the chuck and it locks instantly; press the POM release ring square against the body to free it. This is the standard resin one-touch profile, not the metal line: working pressure 0-1.0 MPa, vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa and a temperature window of -20 to +70 C, so the tube you pick becomes the limit in hot environments.

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 PC6M5 Is Used
Compact gripper and mini-cylinder ports
Small-bore parallel grippers and Dia 10-16 pneumatic cylinders are usually tapped M5. The PC6M5 turns one of those ports straight into a 6 mm supply line without an adaptor block, keeping the envelope close to the moving jaw.
Analytical and dosing instrument feed
Lab analysers, ink-dosing heads and sample-handling modules run 6 mm PU line at low pressure. The gasket-sealed M5 stud avoids thread sealant particles migrating into a precision fluid or air path.
Manifold-mounted valve subplates
Compact valve manifolds and pilot subplates commonly carry M5 tapped pilot ports. PC6M5 gives each pilot feed its own push-in outlet so a single 6 mm nylon run can loop from valve to valve.
Is the Airtac PC Threaded Straight Connector PC6M5 the Right Part?
M5 on the PC series is only catalogued in Dia 4 and Dia 6, so PC6M5 is the top of the M5 tube ladder. Step down to PC4M5 for a 4 mm line with lower flow capability tied directly to the smaller bore; if your line needs Dia 8 or larger, the M5 stud itself is the ceiling and you should move to PC801, which carries the same Dia 8 tube on a 1/8in PT thread instead. The thread here is fixed at M5x0.8 by the port you are filling, so match it to the tapped port on the valve, cylinder or sensor head, not to neighbouring sizes.
Tube OD must match exactly. A Dia 6 fitting holds Dia 6 tube only; a nominal 1/4in (6.35 mm) tube will not seal in the chuck and will blow off under pressure.
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 PC6M5 FAQ
It is an AirTAC PC one-touch male connector with a Dia 6 mm tube outlet and an M5x0.8 male thread (gasket sealed). Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum capability to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and operating temperature -20 to +70 C. It takes soft nylon or polyurethane tube in 6 mm OD only.
No. The chuck is machined for exactly 6.0 mm OD; 1/4in tube measures about 6.35 mm and will not seat in the stainless spring gasket, so it leaks or blows out. Use true 6 mm soft nylon or PU tube, or move to a fitting sized for the actual tube you have.
