About the Airtac PC Threaded Straight Connector PC802D-S
The PC802D-S is AirTAC's PC series one-touch male connector in the SUS304 stainless variant, joining Dia 8 mm soft nylon or polyurethane tubing to a 1/4 inch PT male thread. On the PC and POC straight connectors the -S suffix makes the fitting body itself stainless steel 304, and AirTAC states that all parts of the assembly are copper-free - a distinction that matters on plating lines, in electronics plants and anywhere copper ions can contaminate a process.
Connection is the standard push-to-connect action: push the tube square into the collet until it bottoms, and the stainless spring gasket and chuck grip it against the POM seal; press the release button to free it. Ratings are identical to the standard grey PC802: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, and -20 to +70 C. The black D code applies to the release button on this series, so a technician can spot the stainless part at the panel even though the body reads as bare metal.

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 PC802D-S Is Used
Electroplating and surface treatment cells
Copper-free SUS304 air drops feeding rinse and grip cylinders above plating tanks, where copper alloy fittings can leach ions into bath chemistry and standard brass bodies corrode.
Food packaging machine washdown zones
Dia 8 runs to a bagger's sealing-jaw cylinder on a line that is hosed down each shift; the stainless body shrugs off the caustic foam that pits plated brass connectors.
Semiconductor tool nitrogen distribution
Push-in taps off a 1/4 inch PT purge manifold inside a copper-restricted process tool, where any fitting metalwork downstream of the MFC must be copper-free.
Is the Airtac PC Threaded Straight Connector PC802D-S the Right Part?
Tube side, the neighbours on the 1/4 inch thread are PC602-S (Dia 6, one step down) and PC1002-S (Dia 10, one step up). Stepping down lightens the loop and suits smaller actuator ports; stepping up gives a stiffer circuit with more capacity per length of run. Thread side, the Dia 8 tube also comes on PC801-S (1/8 inch) and PC803-S (3/8 inch), so match the thread to the port on the valve or cylinder rather than forcing an adapter into the circuit.
Tubing OD must match the fitting exactly - a Dia 8 chuck will not seal on 5/16 inch imperial tube. The 1/4 inch thread arrives with sealant pre-applied, so do not add paste or tape on top of it.
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 PC802D-S FAQ
It is a SUS304 stainless one-touch male connector: Dia 8 mm tube port, 1/4 inch PT male thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum capability -750 mmHg (10 Torr), operating temperature -20 to +70 C, for soft nylon or polyurethane tubing. Pressure and temperature figures are identical to the standard PC802 - stainless changes the material, not the rating.
The fitting body is stainless steel 304 and the assembly is copper-free throughout; the release button and chuck remain POM, the guide is aluminium alloy, the spring gasket stainless and the seal an NBR O-ring. Dimensions match the standard grey version exactly, so a PC802D-S is a like-for-like swap into an existing Dia 8 / 1/4 inch position without re-piping.
