The AirTAC Airtac POC Round Thread Straight Connector POC1004D-S is a genuine male connector (compact) for push-in tube connection, rated 0 - 1.0 MPa (0 - 10 kgf/cm2) with a 1.5 MPa proof pressure.
The POC1004D-S is AirTAC's compact one-touch male connector in the SUS304 stainless variant, joining Dia 10 mm soft nylon or polyurethane tube to a 1/2" PT male thread. Push the tube straight into the chuck and the stainless spring gasket grips it for a pressure-tight joint; press the release ring and the tube slides straight back out. The POC body is the shorter, more compact version of the PC connector, so it fits ports where thread length or panel clearance is tight.
The -S suffix matters most on this family: on a POC the body itself is made from Stainless steel 304, and AirTAC states all parts are copper-free, which suits electronics assembly, plating lines and other processes where copper contact is unwanted. The D suffix changes only the release button to black - on this stainless version the body is already SUS304, so the black button is the visual cue on the machine. Ratings are unchanged from the standard resin line: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, -20 to +70 C.

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.

Feeding a Dia 10 mm line to a gripper or stopper cylinder on a food or packaging conveyor that is hosed down between shifts, where a brass body would corrode and the 1/2" PT port matches the valve manifold outlet.
Air lines running near electroplating tanks and rinse stations, where the copper-free SUS304 construction avoids copper contamination in the bath chemistry and resists the corrosive mist.
Supplying vacuum ejectors or pnestatic clamps on SMT and semiconductor handling equipment, where copper-free pneumatic components are specified to protect cleanroom processes and sensitive boards.
This is the smallest tube AirTAC offers on a POC 1/2" thread - only Dia 10 and Dia 12 exist on 1/2" for this series, so there is no smaller step on the same thread. Step the thread down to 3/8" and the POC1003 carries the same Dia 10 tube on a smaller port; step the tube up to Dia 12 on the same 1/2" thread and you get the POC1204 for higher-volume actuator feeds. Match the 1/2" PT thread to the port size first, then fix the tube OD - a Dia 10 chuck will not hold 3/8" (10 mm nominal inch) tube, and tube OD must match exactly.
If you need to pass through a panel wall rather than terminate on a port, the bulkhead shapes (PMF / PLM) are the right family instead, and if the run must turn, the PL or PH elbows save a bend in the tube. Note that on elbows and tees the -S variant means only the stud is SUS304 - it is specifically the straight POC and PC bodies that go solid stainless.
Quick checklist
It is a compact one-touch male connector with a Dia 10 mm tube chuck on a 1/2" PT male thread, body in Stainless steel 304 with a black release button. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C, for soft nylon or polyurethane tube.
No. The chuck grips exactly Dia 10 mm outside-diameter soft nylon or polyurethane tube - the one-touch seal depends on the OD matching precisely, so no inch-sized hose and no other metric size will seat in this one part. For 12 mm tube on the same 1/2" thread order the POC1204; for 10 mm tube on a smaller port order the POC1003 with its 3/8" thread.
