About the Airtac PC Threaded Straight Connector PC601D-S
The PC601D-S is an AirTAC PC series one-touch male connector in the SUS304 stainless variant, joining Dia 6 mm soft nylon or polyurethane tubing to a 1/8in PT male thread. On the PC and POC straight connectors the -S suffix means the body itself is stainless steel 304 and the whole fitting is copper-free; the black D suffix here changes the release button colour, not the shape or the ratings. Press the tube home and the stainless spring gasket plus POM chuck grip it instantly; press the release ring and it slides free.
This is the resin/brass spec profile, not the 0.9 MPa metal line: working pressure 0-1.0 MPa, vacuum to -750 mmHg, proof pressure 1.5 MPa, and a -20 to +70 C temperature window. The 1/8in thread arrives with sealant already applied, so it seats straight into a PT port without extra tape. Because the body is 304 stainless, the fitting suits corrosive or wash-down air circuits where a brass body would pit or contaminate.

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 PC601D-S Is Used
Electronics assembly air lines
Copper-free SUS304 construction keeps the PC601D-S suitable for pneumatic pick-and-place lines in semiconductor and PCB plants, where copper particles or copper-catalysed reactions on sensitive assemblies are a concern.
Wash-down fixture clamping
On food and packaging machinery jigs that get hosed down each shift, a 1/8in stainless connector feeding a Dia 6 clamp cylinder resists the corrosion that pits brass fittings in the same position.
Plating and chemical bath actuation
A 1/8in PT thread onto a solenoid valve outlet, with Dia 6 nylon run to a small lift cylinder above an electroplating tank, where acidic vapour would quickly attack a plated brass body.
Is the Airtac PC Threaded Straight Connector PC601D-S the Right Part?
Dia 6 with a 1/8in thread sits mid-ladder for the PC series: PC401 steps down to Dia 4 for thin signal tubing on compact actuators, while PC801 steps up to Dia 8 for higher-volume cylinder feeds on the same 1/8in port. If your port is 1/4in instead, the equivalent part is the PC602. Whichever you pick, the tube OD must match exactly - a Dia 6 chuck will not seal on 1/4in (6.35 mm) tube, and forcing it is the most common cause of a slow leak.
Choose this stainless version when the air side sees moisture, condensate or wash-down splash, or when copper-free construction matters downstream, as in electronics assembly or plating shops. For a thread-only material upgrade where the body can stay PBT, the PL family with an SUS304 stud is the lighter alternative.
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 PC601D-S FAQ
It is an AirTAC PC one-touch male connector for Dia 6 mm soft nylon or polyurethane tube with a 1/8in PT male thread, SUS304 stainless body, copper-free, black POM release button. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The thread carries factory-applied sealant.
No. On the PC series the D suffix changes only the release button colour to black; the body here is SUS304 because of the -S suffix. The stainless variant keeps the identical pressure, vacuum and temperature figures as the standard part, and the dimension tables match, so you can swap it into an existing brass PC601 position without redrawing anything.
