About the Airtac POC Round Thread Straight Connector POC801D-S
The POC801D-S is AirTAC's compact one-touch male connector in the SUS304 stainless variant, joining Dia 8 mm soft nylon or polyurethane tubing to a 1/8in PT male thread. Push the tube into the chuck and it grips for a pressure-tight seal; press the POM release ring and the tube frees for repositioning. The D suffix sets the release button to black, and on POC that button colour is the only thing D changes.
Because this is the -S version, the connector body itself is Stainless steel 304 and AirTAC states all parts are copper-free - the reason corrosion-sensitive and plating-line buyers specify it. Ratings are unchanged from the standard part: 0-1.0 MPa working pressure, 1.5 MPa proof pressure, -750 mmHg vacuum and -20 to +70 C. The dimension tables match the grey POC801 exactly, so it drops into the same drilled port without redesign.

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 POC801D-S Is Used
Electroplating and surface-treatment lines
A copper-free SUS304 body next to plating baths and rinse stations avoids copper contamination in the chemistry, where a standard brass-bodied POC801 would be the wrong choice.
Food wash-down conveyor actuation
Dia 8 tube feeding a small poppet cylinder on a packaging conveyor, hosed down daily - the stainless body shrugs off splash while the compact POC footprint fits under the guarding.
Corrosive-gas lab manifolds
Straight into a 1/8in PT port on a fume-hood or analytical-instrument manifold, with 8 mm polyurethane runs to each sampling valve that can be released and re-routed in seconds.
Is the Airtac POC Round Thread Straight Connector POC801D-S the Right Part?
On the 1/8in PT thread ladder for POC, Dia 8 sits between POC601 (Dia 6) and POC1001 (Dia 10). Stepping down to Dia 6 saves panel space on light pilot lines; stepping up to Dia 10 gives a fatter bore for short cylinder or valve feeds. If your port is 1/4in PT, the matching part is POC802 rather than forcing a reducer behind this one.
Match the thread to a PT-taped or pre-sealed port - AirTAC ships the stud with sealant already applied. And check tube OD before ordering: a Dia 8 chuck will not hold 1/4in (6.35 mm) hose, only true 8 mm OD tube.
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 POC801D-S FAQ
It is a compact one-touch male connector for Dia 8 mm soft nylon or polyurethane tube with a 1/8in PT male thread. 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. The body is Stainless steel 304, copper-free per AirTAC, with POM release button and chuck, aluminium-alloy guide, stainless spring gasket and NBR O-ring.
No. Pressure, vacuum, proof pressure and temperature ratings are identical, and the dimensions match, so it fits the same port. The difference is the material: a SUS304 body with copper-free construction for corrosion resistance, not a re-rated part. AirTAC publishes no surface-finish, passivation or certification figures for the stainless line.
