About the Airtac PC Threaded Straight Connector PC602D-S
The PC602D-S is AirTAC's PC series male connector built on a SUS304 stainless body, joining Dia 6 mm soft nylon or polyurethane tube to a 1/4in PT male thread. Push the tube home and the internal chuck grips it under the spring gasket; press the release ring and it frees again. Unlike the standard PC range, where the brass body sits under a PBT or plated shell, this -S variant makes the load-bearing body itself stainless steel 304, and AirTAC states every part of it is copper-free.
It still runs the resin-line spec profile: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. The black D suffix changes only the release button colour, so the fitting reads low-profile on dark machine frames. The 1/4in thread arrives pre-coated with sealant, ready to wind straight into a PT port.

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 PC602D-S Is Used
Electroplating line air drops
Copper-free SUS304 construction keeps dissolved copper out of the air supply above plating tanks, where brass fittings can contaminate the bath chemistry via condensate and carry-over.
Food wash-down conveyor actuators
On a snack-line conveyor with periodic caustic hose-down, the stainless body and black button resist the wash environment that would pit a plated brass PC602 within months.
Marine control cabinet air feed
A salt-humid engine-room cabinet feeding Dia 6 line to dampers and indicators suits the 1/4in male stud landing on a bulkhead-mounted valve manifold.
Is the Airtac PC Threaded Straight Connector PC602D-S the Right Part?
On the PC 1/4in ladder you can step down to Dia 4 (PC402-S) for light signal lines or up to Dia 8 (PC802-S) when the actuator needs more bore; each step changes the tube bore you can feed, so match it to the cylinder port or valve station, not to guesswork. Holding tube size and moving thread, PC601-S drops to 1/8in for compact valve manifolds and PC603-S rises to 3/8in for larger ports. Remember the tube OD must match exactly: a Dia 6 connector will not seal on 1/4in (6.35 mm) tube, even though the numbers look close. If you need the same joint turned through 90 degrees, the PL stainless elbow family is the shaped alternative.
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 PC602D-S FAQ
Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum rating is -750 mmHg (10 Torr), proof pressure is 1.5 MPa and the temperature range is -20 to +70 C. This SKU connects Dia 6 mm soft nylon or polyurethane tube to a 1/4in PT male thread. The stainless body does not change any of these figures from the standard PC602D.
No. On the PC connector family the D suffix changes the POM release button to black; it does not change the body material or shape. On this -S variant the body is SUS304 stainless regardless of the colour code, so you get a stainless connector with a black button rather than a black-painted fitting.
