About the Airtac PC Threaded Straight Connector PC604D-S
The PC604D-S is the SUS304 stainless build of AirTAC's PC series one-touch male connector, joining Dia 6 mm soft nylon or polyurethane tubing to a 1/2 in PT male thread. Push the tube into the chuck and the stainless spring gasket and collet grip it under the collet spring; press the release ring to free it. The resin/brass spec profile applies: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C.
On the PC straight connector the -S option upgrades the body itself to stainless steel 304, and AirTAC states that all parts of this build are copper-free - the reason buyers specify it near plating baths, wash-down zones and copper-sensitive processes. The D suffix makes the release button black; the chuck stays POM, the guide is aluminium alloy and the O-ring is NBR. Ratings, dimensions and the tube/thread ladder are identical to the standard PC604D, so nothing is re-rated. AirTAC ships the male thread with sealant already applied - assemble it as received.

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 PC604D-S Is Used
Bottling line wash-down conveyor
Feeding a small Dia 6 reject-blower or guide-cylinder line from a 1/2 in ported valve manifold on a conveyor that is hosed down between shifts - the SUS304 body shrugs off splash where a grey PBT body would sit and corrode.
Electroplating line air drops
Copper-free construction matters above plating tanks, where copper ions can contaminate the bath chemistry. This connector pairs Dia 6 PU drops to the 1/2 in threaded branch of the rinse-section air header.
Semiconductor tool pneumatic taps
Tapping Dia 6 vacuum and actuation lines off a 1/2 in PT header inside a copper-restricted tool bay, where the one-touch push-fit keeps rework fast without introducing copper parts into the air path.
Is the Airtac PC Threaded Straight Connector PC604D-S the Right Part?
On a 1/2 in PC thread the tube ladder runs 6, 8, 10, 12 mm, so Dia 6 is the smallest tube you can buy with this large a port - there is no PC404. The next step up is PC804, which gains bore area on the same 1/2 in thread if the actuator is flow-hungry. Stepping down on thread instead, PC603 gives the same Dia 6 tube on a 3/8 in port; 1/2 in is the largest thread offered for 6 mm tube. Whichever you pick, the tube must be Dia 6 exactly - a fitting will not seal on 1/4 in (6.35 mm) or any other near-miss OD.
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 PC604D-S FAQ
It is a stainless 304 one-touch male connector taking Dia 6 mm soft nylon or polyurethane tube on a 1/2 in PT male thread. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure is -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the operating temperature range is -20 to +70 C.
No on both counts that matter: the chuck grips Dia 6 mm tube only, so 1/4 in (6.35 mm) tube will not seal and a Dia 8 part is needed for larger bore. The -S variant does not alter dimensions, pressure or temperature ratings versus the standard PC604D - only the body material changes to SUS304, with copper-free parts throughout.
