About the Airtac PC Threaded Straight Connector PC1004-S
The PC1004-S is an AirTAC PC series one-touch male connector in the SUS304 stainless variant, joining Dia 10 mm soft nylon or polyurethane tube to a 1/2 in PT male thread. Push the tube home and the internal chuck grips it; press the release ring and the tube frees off for rework or replacement. On PC and POC straight connectors the -S suffix means the connector body itself is stainless steel 304, and AirTAC states that all parts are copper-free.
Ratings are identical to the standard PC line: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. The release button and chuck remain POM, the guide aluminium alloy and the O-ring NBR, so the corrosion protection lives in the body, not in the seals. AirTAC ships threaded parts with sealant already applied to the 1/2 in PT thread, so no extra tape or paste is needed before installation.

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 PC1004-S Is Used
Washdown food conveyor cylinders
Feeding Dia 10 tube to 1/2 in PT cylinder ports on a meat-processing conveyor that is hosed down every shift, where a plain brass body would pit and copper traces near product are unwelcome.
Plating line pick-and-place
Supplying actuators over acid plating tanks, where fumes attack brass fittings quickly; the copper-free SUS304 body of the PC1004-S and its 1/2 in PT thread suit the rigid drop from the plant air ring main.
Manifold take-off on a carton former
Screwing directly into a 1/2 in PT manifold outlet on a carton-forming machine and running a 10 mm PU line straight to a gripper valve block, keeping the run short and the hex accessible for a spanner.
Is the Airtac PC Threaded Straight Connector PC1004-S the Right Part?
Both neighbours exist on the PC 1/2 in thread ladder: PC804 steps down to an 8 mm bore for smaller cylinder ports, while PC1204 opens to the 12 mm bore that feeds the largest actuators in this range. If the port itself is the constraint rather than the tube, PC1003 carries the same Dia 10 tube on a 3/8 in PT thread and PC1002 fits a 1/4 in PT port. A universal elbow (PH) or a bulkhead version (PM) is the better answer when the tube must turn away from a panel wall rather than run straight off the port.
Tube OD must match exactly. A Dia 10 chuck will not seal on 8 mm or 12 mm tube, and AirTAC publishes no reducer insert for the one-touch chuck, so pick the fitting to the tube first and the thread second.
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 PC1004-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum capability -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. This SKU connects Dia 10 mm soft nylon or polyurethane tube to a 1/2 in PT male thread, and the one-touch body is SUS304 stainless steel with copper-free construction.
No. AirTAC publishes one rating set for the PC line and the -S suffix changes materials only, not performance: 0-1.0 MPa working, 1.5 MPa proof, -20 to +70 C and -750 mmHg vacuum all stay as printed. AirTAC also publishes no corrosion class, surface finish or passivation data for the stainless body, so select on the material grade itself - SUS304, copper-free - rather than on a finish figure.
