About the Airtac POC Round Thread Straight Connector POC802D-S
The POC802D-S is AirTAC's compact one-touch male connector in the stainless -S execution: a SUS304 connector body with a Dia 8 tube port and a 1/4in PT male thread. Push the tube home and the internal chuck grips it; press the release ring and the grip frees the tube, so a Dia 8 line is hooked to a 1/4in port in seconds without tools. The POC body is the shorter cousin of the PC connector, which matters where port pitch on a manifold is tight.
The -S suffix makes the connector body itself Stainless steel 304 and the whole part copper-free, while the release button and chuck stay POM, the guide stays aluminium alloy, the spring gasket is stainless and the O-ring is NBR. Ratings are identical to the standard resin line: 0-1.0 MPa working, -750 mmHg vacuum, 1.5 MPa proof, -20 to +70 C. A detail buyers often miss: on the POC series the D suffix colours only the release button (black here) and never the body, so your stainless look is unaffected.

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 POC802D-S Is Used
Copper-free plating jigs
On PCB copper-plating and electroplating lines, the SUS304 copper-free wetted body keeps dissolved copper out of the chemistry, and the compact POC profile clears neighbouring jig plumbing.
Marine wash-down cabinets
Feeding solenoid valves for bow-thruster or deck-machinery controls, the 304 body shrugs off salt spray that would creep-corrode a plated brass connector.
Dense electronics test manifolds
Where a standard PC connector is too long for tightly pitched 1/4in ports on a semiconductor test rig, the shorter POC802D-S body fits without cross-threading the next valve.
Is the Airtac POC Round Thread Straight Connector POC802D-S the Right Part?
Look one step each way on the POC 1/4in ladder: POC602 serves Dia 6 tube feeding lighter actuators and pilot lines, while POC1002 is the choice when the Dia 10 run carries the main supply off the manifold. If the port itself is smaller, POC801 moves this fitting down to a 1/8in thread. Whatever you pick, tube OD must match exactly - the chuck seals on the tube surface, so a Dia 8 pocket will not hold 1/4in (6.35 mm) imperial tube.
The 1/4in PT taper thread is sealed at assembly in the usual way with tape or thread sealant; the stainless body does not change the sealing method or any rating versus the standard POC802.
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 POC802D-S FAQ
It is a compact one-touch male connector for Dia 8 tube with a 1/4in PT male thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. The SUS304 -S body carries exactly the same pressure and temperature figures as the standard POC802; only the corrosion resistance and copper-free construction change.
Yes. The chuck accepts soft nylon or polyurethane in Dia 8 OD. Match the OD exactly, because the grip and seal are on the tube surface: 1/4in (6.35 mm) imperial tube will not seat in a Dia 8 pocket. Also note the -20 to +70 C ceiling comes from the NBR O-ring and POM release button, not the SUS304 body, so the stainless build does not buy you extra temperature range on this series.
