About the Airtac POC Round Thread Straight Connector POC802-S
The POC802-S is the SUS304 stainless version of AirTAC's POC compact male connector. It joins Dia 8 mm soft nylon or polyurethane tubing to a 1/4 PT male thread, using the same one-touch action as the standard line: push the tube home and the internal chuck grips it, press the release ring to free it. On the POC straight-connector family the stainless goes deeper than a plated stud - the body itself is machined from Stainless steel 304, and AirTAC states all parts are copper-free.
It runs the standard resin spec profile, not a re-rated one: 0-1.0 MPa working pressure (0-10 kgf/cm2), -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C. The release button and chuck stay POM, the guide is aluminium alloy, with a stainless spring gasket and NBR O-ring. Thread sealant is applied at the factory; no additional tape is required for a sound joint.

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 POC802-S Is Used
Plating-line rinse stations
Copper-free SUS304 construction suits rinse and rinse-to-waste lines on electroplating jigs, where a standard brass body could leach copper into the bath chemistry.
Wash-down food conveyor actuation
Feeds Dia 8 mm lines to small pneumatic grippers and stopper cylinders on dairy and bakery conveyors that are hosed down daily, where plated brass would pit.
Electronics tooling manifolds
Steps a 1/4 PT manifold port down to Dia 8 mm tubing feeding pick-and-place vacuum ejectors and air blow-off nozzles on SMT handling equipment.
Is the Airtac POC Round Thread Straight Connector POC802-S the Right Part?
On the 1/4 PT thread, POC steps from Dia 4 up to Dia 12. Dia 6 (POC602) buys you a slimmer profile for short runs and light actuators; Dia 10 (POC1002) moves more air at the same pressure drop because the bore, not the fitting, sets the flow limit. Stepping from 8 to 10 also means the release collar gets easier to work with gloved hands. Always match the tube OD exactly - a Dia 8 chuck will not seal 5/16 inch tube, and there is no imperial equivalent in this catalogue.
Choose the -S over the grey or black POC802 when the fitting sees wash-down, brine, plating-bath mist or any process where copper contamination matters - electronics manufacturing and certain food and plating lines are the typical buyers. Note that the dimension tables match the standard part, so it drops straight into existing drawings with no redesign.
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 POC802-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. It connects Dia 8 mm soft nylon or polyurethane tube to a 1/4 PT male thread. The body is Stainless steel 304 and the construction is copper-free; the release button and chuck are POM, the guide aluminium alloy, with a stainless spring gasket and NBR O-ring.
No on both counts. AirTAC rates the SUS304 version at exactly the same pressures and temperatures as the standard POC802, and the dimension tables are identical, so it replaces the standard part without altering your panel layout. What changes is corrosion resistance and the copper-free metallurgy. Also remember that at any elevated temperature the tubing itself, not the fitting, is usually the limiting component.
