About the Airtac POC Round Thread Straight Connector POC6M5-S
The POC6M5-S is the SUS304 stainless-steel version of AirTAC's POC compact male connector, a one-touch fitting that pushes onto Dia 6 mm soft nylon or polyurethane tube and screws into an M5x0.8 metric port. On the POC family the -S option makes the connector body itself stainless 304, and AirTAC states that all parts of the assembly are copper-free. The release button and chuck stay POM, the guide is aluminium alloy, the spring gasket is stainless and the O-ring is NBR.
Push the tube straight into the chuck until it stops and the gasket and chuck lock it; press the release ring and the tube slides back out. Ratings are identical to the grey resin POC: 0-1.0 MPa (0-10 kgf/cm2) working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C. The -S suffix changes the material, never the numbers. As on every M5 thread in this catalogue, the joint closes on a sealing gasket rather than pre-applied thread sealant.

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 POC6M5-S Is Used
Cobot gripper air feed
A 6 mm line feeding a compact parallel gripper on a collaborative-robot wrist, where the M5 port sits between closely spaced wrist components and the POC's short body clears the neighbours.
Analytical instrument pneumatics
Carrier-air and actuation lines inside a laboratory analyser or sample-handling skid, where a copper-free SUS304 circuit prevents metal contamination reaching the process stream.
Pilot feed on a compact valve island
Screwing into the M5 pilot port of a small solenoid valve manifold on an electronics assembly machine, where pitch between ports is too tight for a full-size PC body.
Is the Airtac POC Round Thread Straight Connector POC6M5-S the Right Part?
Dia 6 mm is the largest tube AirTAC pairs with M5 on the POC ladder - M5 exists only in 4 and 6 mm here - so the POC4M5-S is the only step down, trading bore for a slimmer 4 mm line. If you need to keep Dia 6 tube but want a coarser threaded port, the next rung is the POC601-S on a 1/8in thread. The POC body is the more compact of the two straight-connector families, which matters when a fitting has to sit between closely pitched M5 ports on a valve manifold. Tube OD must match exactly: this fitting grips 6 mm tube only and will not seal on 1/4in.
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 POC6M5-S FAQ
It is a stainless one-touch male connector joining Dia 6 mm soft nylon or polyurethane tube to an M5x0.8 thread, closed with a sealing gasket. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa and temperature range -20 to +70 C. The connector body is SUS304 and the assembly is copper-free; the release button and chuck are POM, the guide aluminium alloy, the spring gasket stainless and the O-ring NBR.
No. The SUS304 body replaces the standard body material and adds copper-free construction, but every rating is identical to the grey POC: 0-1.0 MPa working, 1.5 MPa proof, -750 mmHg vacuum and -20 to +70 C. Choose this part for corrosion resistance or for circuits where copper must be kept out of the air path, not for higher pressure or heat.
