About the Airtac PC Threaded Straight Connector PC1004D-S
The PC1004D-S is AirTAC's SUS304 stainless version of the PC series one-touch male connector, sized to push a Dia 10 mm soft nylon or polyurethane tube onto a 1/2 inch PT male thread. Unlike the PL, PLL and branch families, where only the stud goes stainless, on the PC straight-connector range the body itself is stainless steel 304, and AirTAC states the whole part is 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. The D suffix in this code changes the release button to black - on PC and POC fittings it never changes the body, which here is stainless in every case.
Connection is genuinely one-touch: push the 10 mm tube firmly into the chuck and the grip ring locks it against the stainless spring gasket; press the release ring and the tube slides free for rework or re-routing. It runs on the standard resin-line ratings, which -S does not alter: 0-1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C. AirTAC ships the PT thread with sealant already applied, so it seals straight into the port.

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 PC1004D-S Is Used
Wash-down conveyor actuator feed
On a food-plant washdown conveyor, the 1/2in PT thread drives the main cylinder, while the SUS304 copper-free body shrugs off daily caustic rinse that pits brass fittings.
Plating-line rinse manifold
In an electroplating shop, the Dia 10mm bore feeds rinse-station air near acid mists; the stainless 304 body avoids the copper ions that contaminate plating baths.
Marine deck air supply
On a boat's deck-mounted actuator circuit, salt spray destroys plated brass in months; the copper-free SUS304 body and black POM button of the PC1004D-S keep the 1/2in port sealed season after season.
Is the Airtac PC Threaded Straight Connector PC1004D-S the Right Part?
On the PC row of the interface table, a 1/2 inch thread is offered in Dia 6, 8, 10 and 12 mm tubes. The neighbours of this part are PC804-S one step down (Dia 8, a slimmer bore for lighter actuators and shorter runs) and PC1204-S one step up (Dia 12, the largest bore the 1/2 inch PC thread accepts, for main air headers feeding multiple branches). Stepping a size changes flow capacity through the bore, not the thread - the 1/2 inch port stays the same, so a mid-line change needs no re-tapping.
Match the thread to a female 1/2 inch PT port; there is no G or NPT variant in this catalogue, so order an adapter if your port differs. Tube OD must match exactly - a Dia 10 fitting will not grip 3/8 inch or 12 mm tube, and forcing a near-size in is the usual cause of leaks under pressure. If you need to exit a panel wall rather than a port, PM or PLM bulkhead shapes are the right answer instead.
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 PC1004D-S FAQ
It is a SUS304 stainless one-touch male connector for Dia 10 mm soft nylon or polyurethane tube with a 1/2 inch PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum is down to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. These ratings are identical to the grey and black resin-line PC fittings - the -S stainless option changes the material, never the pressure figures.
No. AirTAC publishes this variant only in SUS304 - grade 316 is not offered. On the PC straight-connector family the body itself is the stainless steel 304 part and the construction is copper-free, which matters in plating, electronics and food-wash areas. The release button and chuck remain POM and the O-ring is NBR. No surface-finish, passivation or certification figures are published, so none should be specified.
