About the Airtac PC Threaded Straight Connector PC6M5-S
The AirTAC PC6M5-S is the SUS304 stainless version of the PC male connector, a one-touch push-in fitting that joins Dia 6 mm soft nylon or polyurethane tubing to an external M5x0.8 male thread (PT thread standard). Push the tube home and the stainless spring gasket and chuck grip it under system pressure; press the POM release ring and the tube slides straight back out. The body itself is machined from Stainless steel 304 and AirTAC states all parts are copper-free, while the release button and chuck stay POM and the O-ring is NBR.
This is the resin-line spec profile, unchanged by the -S option: working pressure 0-1.0 MPa, vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a working temperature of -20 to +70 C. Because M5 is too small a thread for taper sealant, this size arrives with a sealing gasket on the port instead of pre-applied thread coating, so it seats into the tiny tapped ports found on miniature valves and vacuum components without extra paste.

POM release button and chuck, aluminium-alloy guide, stainless spring gasket, NBR O-ring; body brass or PBT depending on the part. Stainless (-S): SUS304 in place of brass - a solid SUS304 body on the PC and POC straight connectors, and a PBT body with a SUS304 stud on the elbow, tee and branch shapes. Working pressure, proof pressure and temperature are unchanged from the standard version. AirTAC publishes flow as a characteristic curve rather than a single figure, so no L/min value is listed.

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-S Is Used
Vacuum ejector supply on a pick-and-place head
Dia 6 supply lines routed to compact ejectors on PCB-handling gantries land on M5 tapped ports; the stainless, copper-free body suits cleanroom-adjacent electronics assembly where copper particulate is unacceptable.
Pilot port of a miniature valve on a plating line
Small directional valves controlling rinse-actuation cylinders carry M5x0.8 pilot ports; the gasket-sealed male thread installs without sealant that acidic washdown mist could attack, and 304 shrugs off corrosive vapours.
Sensor and indicator tubing on a lab gas skid
Analytical instrument panels use Dia 6 polyurethane drops from M5 stubs on gauges and transducers; the -20 to +70 C window and one-touch release make instrument swaps a press-and-pull job.
Is the Airtac PC Threaded Straight Connector PC6M5-S the Right Part?
On the PC ladder, M5 supports only Dia 4 and Dia 6 tube, so PC6M5-S is the largest tube you can pair with an M5 port - there is no Dia 8 or bigger behind this thread. The smaller neighbour is PC4M5 (Dia 4); step down to it when feeding a light sensor or indicator circuit where flow demand is minimal. If your actuator needs Dia 8 tube, move up to a 1/8 in port such as PC801 rather than trying to force a size mismatch.
Tube OD must match exactly: a Dia 6 fitting will not seal on 1/4 in tube. Pick this SKU when the port itself dictates the choice - a tapped M5x0.8 boss on a valve, ejector or manifold - and note that the copper-free 304 body is the reason to specify the -S over standard PC601, particularly in plating shops or electronics production where copper traces on parts cause contamination or catalytic reactions.
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-S FAQ
It is a Dia 6 mm one-touch male connector with an M5x0.8 external thread (PT standard). Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum capability is -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. It accepts soft nylon or polyurethane tubing only, and the -S option makes the connector body SUS304 with copper-free construction; no pressure or temperature figure changes versus the standard grey PC601.
No. M5 sizes in this range ship with a sealing gasket on the thread instead of the sealant coating applied to larger PT threads, so the fitting seals into the tapped port as installed. Hand-tighten plus a small snug with a spanner is enough; never paste or tape an M5 gasket-sealed stud, as debris can hold the gasket off its seat and cause a slow leak at vacuum.
