About the Airtac POC Round Thread Straight Connector POC1003D-S
The POC1003D-S is AirTAC's compact POC one-touch male connector in its SUS304 stainless version, joining a Dia 10 mm soft nylon or polyurethane tube to a 3/8in PT male thread. POC is the shorter-bodied sibling of the PC connector, so it reaches into ports where space above the thread is limited. Push the tube home and the stainless spring gasket and chuck grip it; press the release ring and the tube frees off again. The -S suffix makes the connector body itself SUS304, and AirTAC states all parts of this variant are copper-free - on several other series only the stud is stainless, so the POC body treatment is the stronger construction. The release button and chuck remain POM, the guide stays aluminium alloy and the O-ring is NBR.
This is the resin-line pressure profile, unchanged by the stainless body: 0 to 1.0 MPa working (0 to 10 kgf/cm2), -750 mmHg vacuum (10 Torr), 1.5 MPa proof pressure and -20 to +70 C. The D suffix here marks a black release button. The 3/8in thread arrives with sealant applied, ready to screw straight into a PT 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 POC Round Thread Straight Connector POC1003D-S Is Used
Bottling line washdown zones
SUS304 body and copper-free parts stand up to routine spray-down around rinser and filler stations on a bottling machine, where a bare brass connector would tarnish and stain. Dia 10 tubing carries the cylinder supply on the larger gripper and lift actuators.
Plating and electronics process air
On plating lines and in electronics plants, copper ions in the airstream can catalyse bath chemistry or contaminate processes. This copper-free connector feeding Dia 10 lines to process valves removes that path.
Packed machine manifolds
The compact POC body screws into valve and cylinder ports where the longer standard PC connector would foul guards or adjacent fittings - common on densely packed rotary indexing tables and packaging heads.
Is the Airtac POC Round Thread Straight Connector POC1003D-S the Right Part?
On the POC 3/8in row the neighbouring sizes are Dia 8 below (POC803) and Dia 12 above (POC1203). Stepping down to Dia 8 buys a slimmer tube route for lighter-duty actuators; stepping up to Dia 12 lowers resistance on longer runs or big-bore cylinders - flow scales with the bore, so match the tube to the air demand of the actuator, not the port alone. Note the 3/8in POC ladder covers 8, 10 and 12 only; smaller POC sizes live on the 1/8in and 1/4in threads instead.
Tube OD must match the connector exactly: a Dia 10 fitting will not seal on 1/4in (6 mm) or 12 mm tube. Check the receiving port too - 3/8in PT suits larger valve and cylinder ports, and a PCF female or PH swivel elbow may suit better if the hose must approach at an angle.
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 POC Round Thread Straight Connector POC1003D-S FAQ
It is a compact one-touch male connector for Dia 10 mm soft nylon or polyurethane tube with a 3/8in PT male thread. Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. The body is SUS304 stainless and the construction is copper-free; the release button and chuck are POM and the O-ring is NBR.
No. Ratings, dimensions and the tube/thread interface are identical to the standard POC1003 - the SUS304 body adds corrosion resistance and copper-free construction, nothing else, so there is no need to re-rate your circuit. The D suffix on a POC changes only the release button colour to black. What does matter mechanically is tube match: seat exactly Dia 10 tube, and rely on the pre-applied thread sealant on the 3/8in stud rather than extra tape.
