The AirTAC Airtac POC Round Thread Straight Connector POC1004-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 POC1004-S is the SUS304 stainless version of AirTAC's POC male connector (compact), a one-touch fitting that joins Dia 10 mm soft nylon or polyurethane tubing to a 1/2in PT male thread. On the POC straight-connector family the -S option upgrades the body itself to stainless steel 304 and makes the whole fitting copper-free - this is a deeper change than on elbow or tee families, where only the stud goes stainless.
Connection is pure push-in: push the tube home and the internal chuck grips it against the stainless spring gasket; press the POM release button to free it. As a resin-line fitting it is rated 0-1.0 MPa (0-10 kgf/cm2) working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. The stainless build changes none of these figures. The 1/2in thread arrives with sealant pre-applied, so it seals straight into a tapped 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.

Copper-free construction makes the POC1004-S a safe air pick-off above plating and rinse tanks, where traces of dissolved copper would contaminate the bath chemistry.
The shorter POC body clears narrow manifolds and guarded slide tables where a full-length PC connector would foul the machine frame, with Dia 10 tube feeding a 1/2in ported cylinder.
On food and packaging conveyors hosed down between shifts, the SUS304 body resists splash corrosion that pits a brass fitting, while the POM release button still allows fast tube changes.
Within the POC ladder, the 1/2in thread exists only in Dia 10 and Dia 12, so POC1204 is the single step up - one size on both tube and thread capacity, for lines feeding bigger bore actuators. There is no Dia 8 at 1/2in on POC: to step down you move to POC1003 (Dia 10 on a 3/8in thread) or POC0803 (Dia 8, 3/8in). Always confirm the port thread and tube OD match exactly - a Dia 10 chuck will not hold 3/8in hose.
Choose POC over the standard PC when port clearance is tight: the compact body shortens the stack-up at the fitting. Choose the -S build when the circuit must be copper-free, for example in electronics or plating plant, or where wash-down splash would attack brass.
Quick checklist
It is a compact one-touch male connector joining Dia 10 mm soft nylon or polyurethane tube to a 1/2in PT thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg, proof pressure 1.5 MPa, operating temperature -20 to +70 C. The body is SUS304 stainless steel 304 and the build is copper-free; the release button and chuck are POM, the guide is aluminium alloy, the spring gasket is stainless and the O-ring is NBR.
No. The -S suffix changes the body material to SUS304 and makes the fitting copper-free; every pressure, vacuum and temperature figure, the dimensions and the tube/thread combination are identical to the standard part. Note the limits of the copper-free claim on this family: the release button and chuck remain POM and the O-ring stays NBR, so full all-stainless wetted construction is not what -S means here.
