About the Airtac POC Round Thread Straight Connector POC602D-S
The POC602D-S is AirTAC's compact one-touch male connector in the SUS304 stainless variant, joining Dia 6 mm soft nylon or polyurethane tubing to a 1/4in PT male thread. Push the tube home and the internal chuck grips it straight away; press the release ring and the tube slides back out for rework. The D suffix on a POC part changes the release button to black - the body itself is the stainless item regardless of that letter. In the -S build the connector body is stainless steel 304 and AirTAC states all parts of it are copper-free, while the release button and chuck stay POM, the guide aluminium alloy, the spring gasket stainless and the O-ring NBR.
Ratings are exactly those of the standard resin line - stainless changes the material, not the numbers: 0 to 1.0 MPa (0 to 10 kgf/cm2) working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C. The 1/4in thread arrives with sealant already applied to the PT thread, so no extra tape is needed at the port. Dimensions match the grey POC602 exactly, so a stainless swap needs no redesign of the manifold.

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 POC602D-S Is Used
Food-line wash-down drop to a small gripper
On a packaging machine that gets hosed down each shift, a SUS304 POC602D-S at the valve manifold takes Dia 6 polyurethane tubing out to the gripper without the corrosion a brass body would show over time.
Copper-free air feed on a plating line
Electroplating and similar chemistries can attack copper alloys in the air circuit; the all-copper-free stainless body keeps theDia 6 actuator supply clean and intact near the tanks.
Salt-air instrument air on a vessel
Marine bridge or engine-room instrumentation fed with Dia 6 nylon tube uses this compact 1/4in straight connector where a stainless body shrugs off the salt-laden atmosphere a brass stud would eventually pit.
Is the Airtac POC Round Thread Straight Connector POC602D-S the Right Part?
On the 1/4in thread the POC ladder runs from Dia 4 up to Dia 12, the widest span of any POC thread. Step down to POC402-S for a Dia 4 signal or pilot line, or up to POC802-S when a cylinder of 8 mm bore is being fed and you want lower restriction through the bore. Within Dia 6 itself the thread choices are M5, 1/8in and this 1/4in, so match the stud to the port before you order. The compact POC body sits closer to the port than the standard PC, which matters when a manifold run is tightly pitched.
Tube OD must match exactly - a Dia 6 one-touch will not seal on 1/4in (6.35 mm) tube, and no adapter inside the chuck can fix that. If you actually need a female port or an elbow, move to the POCF or PL family rather than forcing a straight connector into the routing.
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 POC602D-S FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. It joins Dia 6 mm soft nylon or polyurethane tube to a 1/4in PT male thread. The body is stainless steel 304 with all parts copper-free; ratings and dimensions are identical to the standard POC602.
No. On the POC family the D suffix only makes the release button black; on many other AirTAC one-touch series it changes the body as well. Since this is the -S variant, the body is SUS304 stainless either way, so the letter does not affect what you receive apart from the button.
