About the Airtac PC Threaded Straight Connector PC801D-S
The AirTAC PC801D-S is a one-touch male connector from the PC series: a Dia 8 mm tube plugs straight into the fitting and terminates in a 1/8in PT male thread. Push the tube home and the internal chuck grips it under spring load; press the black POM release ring to free it again. On the -S version of the PC line the body itself is machined from SUS304 stainless steel, and AirTAC states all parts of the assembly are copper-free - a detail that matters wherever copper ions can contaminate a process.
This is the resin-line pressure profile, unchanged by the stainless conversion: 0 to 1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum capability, 1.5 MPa proof pressure and a -20 to +70 C temperature window, running on soft nylon or polyurethane tubing. The 1/8in PT thread arrives with sealant already applied. Note the D suffix changes only the release button to black - the chuck, guide and sealing stack remain the standard specification.

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 PC801D-S Is Used
Dairy bottling wash-down lines
Stainless bodies survive daily caustic hose-down on filling and capper machines, where the 8 mm bore feeds grip cylinders and reject pushers straight off 1/8in valve ports.
Plating and electronics wet-process rigs
Copper-free construction prevents metal contamination in pick-and-place air circuits for PCB handling, where copper particles accelerate bath degradation.
Marine deck actuation
Salt-laden air pits brass fitting bodies within a season; the SUS304 body on hatch and wiper actuators resists it, while the 1/8in PT thread suits compact helm-mounted valve ports.
Is the Airtac PC Threaded Straight Connector PC801D-S the Right Part?
Inside the PC 1/8in thread ladder, the sizes either side of Dia 8 are Dia 6 and Dia 10. Step down to PC601-S when feeding smaller pilot valves or compact actuators from the same 1/8in port; step up to PC1001-S when a longer hose run or a larger cylinder bore makes the 8 mm bore the restriction. For bigger ports, the same Dia 8 tube also exists on 1/4in (PC802-S) and 3/8in (PC803-S) threads.
Match the thread to the port first, then the tube. The connection holds only tubing whose OD equals the stated size exactly - a Dia 8 fitting will not seal 1/4in or 5/16in hose, no matter how firmly it is pushed in. If the run needs to turn 90 degrees at the port, the PL stainless-stud elbow is the shape to compare against this straight connector.
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 PC801D-S FAQ
It is a SUS304-body one-touch male connector joining Dia 8 mm tube to a 1/8in PT male thread, with a black release button. Working pressure 0 to 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. Tubing must be soft nylon or polyurethane. The stainless conversion does not alter any of these ratings.
No. The D suffix only changes the release button colour to black; on the PC series it does not change the body, thread or pressure figures. Functionally you can treat PC801D-S and PC801S as the same 8 mm x 1/8in connector, so ordering can follow whatever button colour your panel styling calls for.
