About the Airtac POC Round Thread Straight Connector POC801-S
The POC801-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 1/8 in PT male port, and the compact body is the shorter alternative to the standard PC connector where a straight fitting has to sit closer to the wall or the machine frame.
To make the joint, push the 8 mm tube straight into the chuck until it bottoms out - the stainless spring gasket and POM chuck grip it instantly, and the NBR O-ring seals around the OD. Pressing the release ring frees the tube again for rework. On POC parts the -S suffix changes the body itself to stainless steel 304, and AirTAC states every part of the assembly is copper-free; only the release button (POM) and guide (aluminium alloy) stay as on the standard part. Ratings are unchanged: 0-1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C. The 1/8 in thread arrives with sealant applied.

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 POC801-S Is Used
Plating and surface-treatment lines
A straight shot from an 8 mm manifold drop to a rinse-tank actuator, where a brass body would slowly corrode in acid mist and a copper-free assembly avoids contaminating the bath chemistry.
Marine deck and engine-room air
Feeding 8 mm nylon line to deck-valve pilots and gauge boards on boats, where salt-laden air pits plated brass within a season but a SUS304 body shrugs it off.
Brewery and dairy wash-down stations
A short connector at a 1/8 in port on a rinse or filler cylinder that gets hosed down daily; the stainless body tolerates caustic splash and the compact head clears tight guards.
Is the Airtac POC Round Thread Straight Connector POC801-S the Right Part?
On the POC 1/8 in row the neighbouring tube sizes are Dia 6 below and Dia 10 above. Stepping down to POC601-S gives you a slimmer profile and easier routing in congested panels, at the cost of bore; stepping up to POC1001-S feeds actuators that need more air through the same 1/8 in port. Note the port stays 1/8 in either way - only the grip bore changes.
Match the 1/8 in PT stud to the port before you order anything else: it screws into solenoid valve bodies, cylinder ports and manifold tappings tapped 1/8. The tube OD must match exactly - this chuck holds 8 mm tube only and will not seal on 1/4 in (6.35 in) imperial hose or on 6 mm tube. The -S variant shares the same dimension table as the grey POC801, so it drops into an existing layout without re-drilling anything.
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 POC801-S FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting grips Dia 8 mm soft nylon or polyurethane tube and presents a 1/8 in PT male thread with sealant pre-applied. The body is SUS304 and the whole assembly is copper-free; the chuck and release button are POM, the guide is aluminium alloy and the O-ring is NBR.
Yes, it is dimensionally identical to the grey POC801 - the dimension tables match, so it is a direct swap wherever corrosion resistance is needed. On temperature, the -20 to +70 C window still applies to this resin-button one-touch design; the 0 to +150 C range belongs to AirTAC's separate metal BPC family, not to this part. If you need sustained high temperature, that is a tube-and-fitting decision to make together, since standard nylon and PU tubing are usually the first limit.
