About the Airtac PC Threaded Straight Connector PC604D
The PC604D is an AirTAC PC male connector from the resin one-touch family, with a brass body and a Dia 6 mm tube port on one side and a 1/2in PT male taper thread on the other. Push the soft nylon or PU tube into the collet and the stainless spring gasket and chuck lock it against pressure; press the release ring and the tube slides straight back out. The thread arrives with sealant already applied, so the fitting is ready to wind into the port without extra tape or paste.
This is the standard 1.0 MPa resin profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa and a service temperature of -20 to +70 C. The D suffix on a PC connector changes only the release button to black - the body and every pressure figure stay identical to the standard grey PC604.

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 PC604D Is Used
Large process valve actuator supply
A 1/2in PT port on a pneumatic actuated ball valve or gate valve body takes the PC604D directly, feeding a 6 mm line to the positioner or solenoid pilot without stacking reducers on the valve thread.
Bottling line drop from a 1/2in header
On a rinse-and-fill carousel, the 1/2in PT male thread screws straight into the air manifold boss, and the Dia 6 mm side runs flexible tubing out to each gripper or blow-off nozzle.
Machining centre coolant-less air circuit
Machine tool builders use a big-port connector like this at the spindle-area distribution block, where the 1/2in PT port matches the casting and the 6 mm tube feeds chip-ejection nozzles.
Is the Airtac PC Threaded Straight Connector PC604D the Right Part?
For a Dia 6 mm tube on the PC ladder, the thread options run M5, 1/8in, 1/4in, 3/8in and 1/2in - so 1/2in is the largest thread AirTAC makes in this tube size, and PC604D is the top of the range. If your port is 3/8in, step down to PC603; there is nothing larger to step up to. Working the other axis, Dia 6 is the smallest tube that pairs with a 1/2in thread on the PC series - the next size up is PC804 on 8 mm tube, then PC1004 and PC1204.
The gap between a 6 mm bore and a 1/2in port is deliberate: it lets a big header or valve port feed a light actuator circuit without a second adapter in line. Match the tube exactly - 1/4in (6.35 mm) imperial tube will not seal in a Dia 6 chuck, and forcing it is the usual cause of slow leaks at commissioning.
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 PC604D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting joins Dia 6 mm soft nylon or polyurethane tube to a 1/2in PT male thread, with sealant pre-applied to the thread. It belongs to the resin one-touch family with a brass body and POM release button, rated 1.0 MPa - not the 0.9 MPa metal BPC line.
On the PC straight connector family the D suffix blackens the POM release button only - the brass body stays the standard grey, and every dimension, pressure and temperature figure is identical to the grey PC604. On most other AirTAC one-touch series a D suffix changes the whole body, which is why buyers sometimes expect a black PC604 body; it does not exist. If you need a fully black body on this size, that is a different series question, not a PC604D variant.
