About the Airtac PC Threaded Straight Connector PC1203D
The AirTAC PC1203D is a PC series one-touch male connector that joins Dia 12 mm soft nylon or polyurethane tubing to a 3/8 inch PT male thread. Push the tube straight into the chuck and the stainless spring gasket plus POM collet lock it against pressure; press the release ring and the tube slides straight back out. No tools, no ferrules, no re-making the joint.
This is the resin and brass one-touch family, so it is rated 0-1.0 MPa (0-10 kgf/cm2) working pressure, 1.5 MPa proof pressure, -750 mmHg vacuum and -20 to +70 C. On the PC series the body itself is brass, which gives the Dia 12 stud the strength to carry a large main-line drop. The D suffix here colours the release button black only - the body stays standard grey - which makes the big button easy to spot when a technician has to break the line under time pressure.

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 PC1203D Is Used
Compressor outlet drop
Terminate a Dia 12 main air drop from the receiver or dryer onto a 3/8 inch shut-off or filter-regulator port, where the brass PC body takes the daily wrench handling a header fitting gets.
Pneumatic press cylinder feed
Feed the large rear port of a compact pneumatic press or clinching cylinder with Dia 12 tubing, giving the fast-extend stroke the bore it needs without throttling the flow at the connector.
Vacuum sheet-handling line
Run a Dia 12 suction line from a multi-cup vacuum gripper panel on a packaging or cartoning machine back to the ejector, using the -750 mmHg (10 Torr) negative pressure rating of the one-touch seal.
Is the Airtac PC Threaded Straight Connector PC1203D the Right Part?
Dia 12 is the top of the PC ladder at 3/8 inch. The only size below it on this thread is Dia 10 (PC1003); stepping down shaves the bore but keeps the same stud, useful when the downstream actuator only needs a Dia 10 feed and you want to standardise on one port size. There is no Dia 16 option in this catalogue, so if your machine genuinely needs more bore than 12 mm you must split the flow across two connectors instead of upsizing.
Match the 3/8 inch PT stud to a port tapped at that size - dropping a 3/8 stud into a 1/4 tapped manifold with adaptors adds leak points. AirTAC ships the thread pre-coated with sealant, so hand-tighten plus a modest turn is normally enough; do not add paste or tape over the factory coating. And remember the rule that never bends: tube OD must match exactly, so a Dia 12 fitting will not grip 1/2 inch tube even though the numbers look close in inches.
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 PC1203D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, negative pressure down to -750 mmHg (10 Torr), and a service temperature of -20 to +70 C. It connects Dia 12 mm soft nylon or polyurethane tubing to a 3/8 inch PT male thread. The PC body is brass with a POM release button and chuck, an aluminium-alloy guide, a stainless spring gasket and an NBR O-ring. Thread sealant is applied at the factory.
Only in the colour of the release button. On the PC series the D suffix changes the button to black while the brass body stays standard grey, so pressure rating, dimensions and the 3/8 inch PT thread are identical. Many plants use the black button to mark which lines carry higher flow, or simply because the larger button is easier to find and press on a crowded Dia 12 header.
