About the Airtac PC Threaded Straight Connector PC601-S
The PC601-S is the SUS304 stainless-steel version of AirTAC's PC one-touch male connector, joining Dia 6 mm soft nylon or polyurethane tube to a 1/8 in PT male thread. Push the tube home and the chuck grips it; press the POM release button and the tube releases. On this -S build the body itself is Stainless steel 304, and AirTAC states all parts are copper-free - the release button and chuck stay POM, the guide is aluminium alloy, the spring gasket is stainless and the seal is an NBR O-ring.
Ratings are identical to the standard PC601: 0 to 1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C. The 1/8 male thread arrives with sealant pre-applied, and the dimension tables match the brass-bodied version, so the stainless part swaps in without redrawing a bracket or guard.

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 PC601-S Is Used
Bakery and dairy rinse-down cabinets
Taking a Dia 6 nylon drop from a valve manifold to a gripper cylinder inside a washdown enclosure, where a brass body would corrode and the SUS304 body holds up.
Electroplating line jigs
Supplying Dia 6 urethane line to suction cups over plating tanks, using the copper-free construction to avoid copper salts contaminating the bath chemistry.
Electronics fixture benches
Hooking Dia 6 polyurethane tube to the 1/8 PT ports of pick-and-place cylinders in tool rooms where copper contamination of PCB assemblies is a concern.
Is the Airtac PC Threaded Straight Connector PC601-S the Right Part?
Step down to PC401-S (Dia 4, 1/8) for thin pilot and signal lines; step up to PC801-S (Dia 8, 1/8) when the same port feeds a larger-bore actuator and you want more air per stroke through the bore. On the PC prefix the 1/8 thread spans Dia 4 to Dia 12, while the smaller M5x0.8 thread is offered only in Dia 4 and Dia 6 - a useful check before ordering a mini-thread variant. Tube OD must match exactly: the Dia 6 chuck will not seal on 1/4 in (6.35 mm) tubing, and a forced fit risks 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 PC601-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa and a temperature range of -20 to +70 C. This SKU is a Dia 6 mm one-touch male connector with a 1/8 in PT male thread and a SUS304 body, for soft nylon or polyurethane tube. The thread ships with sealant pre-applied.
No. It takes the same soft nylon or polyurethane tube, and the Dia 6 size must match exactly - the -S part shares the standard PC601 dimension tables and the same 0-1.0 MPa / -20 to +70 C rating set. The release button remains POM and the O-ring remains NBR, so check elastomer compatibility first if the fitting will see aggressive chemical splash.
