About the Airtac PC Threaded Straight Connector PC801-S
The PC801-S is AirTAC's SUS304 version of the PC one-touch male connector, joining Dia 8 mm soft nylon or polyurethane tubing to a 1/8 PT male port. Push the tube squarely into the collet until it bottoms out and the stainless spring gasket and chuck grip it under the collet fingers; press the POM release ring and the tube frees for repositioning.
Unlike the -S versions of PL, PLL, PEB, PED and the other shaped bodies - where only the stud is stainless - the PC and POC straight connectors in -S trim have the body itself machined from stainless steel 304, and AirTAC states the whole part is copper-free. The release button and chuck stay POM, the guide is aluminium alloy and the O-ring is NBR. Ratings are identical to the grey standard line: 0-1.0 MPa working, 1.5 MPa proof, -20 to +70 C.

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 PC Threaded Straight Connector PC801-S Is Used
Electroplating and wet-process benches
The copper-free SUS304 body keeps stray copper out of plating baths and rinse manifolds, and the -20 to +70 C window covers ambient rinse-line service on Dia 8 drop lines from a 1/8 PT manifold port.
Washdown conveyor actuation
On food and packaging lines hosed down between shifts, a solid stainless connector body resists the splash-zone corrosion that pits brass fittings on the Dia 8 lines running pick-and-place cylinders.
Semiconductor tool vacuum drops
Rated to -750 mmHg (10 Torr), the PC801-S suits Dia 8 vacuum assist lines on wafer-handling equipment where a copper-free path near process chambers is specified by the tool builder.
Is the Airtac PC Threaded Straight Connector PC801-S the Right Part?
Dia 8 on a 1/8 PT stud sits mid-ladder: step down to the PC601-S (Dia 6 tube) for lighter actuator circuits, or up to the PC1001-S (Dia 10) when cylinder bore and air demand grow and a 6 or 8 mm line would throttle the flow. On the thread side, 1/4 PT also takes Dia 8 tube, but the M5 option on the PC series stops at Dia 6 - if you need M5 you must drop tube size as well.
Keep the tube OD exact: this chuck is set for Dia 8 only and will not seal on 1/4 inch or 10 mm tube. If the connection must pass through a panel or bulkhead instead of landing on a port, the PM bulkhead union or PLM bulkhead elbow is the shape to reach for, not this straight stud.
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 PC Threaded Straight Connector PC801-S FAQ
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; tube size Dia 8 mm soft nylon or polyurethane; thread 1/8 PT. The -S body is stainless steel 304 and copper-free. These figures match the standard grey PC801 exactly - stainless does not change the ratings.
No. The chuck, stainless spring gasket, POM release ring, aluminium guide and NBR O-ring work the same as the standard PC801, and the dimension tables are identical. The only differences are the SUS304 body itself and the copper-free construction. The Dia 8 collet accepts Dia 8 tube only - it will not hold 1/4 inch or 10 mm tube.
