About the Airtac PC Threaded Straight Connector PC1203
The PC1203 is an AirTAC PC series male connector, the largest standard bore in the resin one-touch range: a Dia 12 mm tube outlet on a 1/4 inch PT male thread. Push the soft nylon or polyurethane tube into the chuck until it bottoms, and the stainless spring gasket and POM chuck grip it for a sealed joint; press the release ring and the tube slides straight back out. The body is brass with a brass stud, and the thread arrives with sealant already applied, so it goes onto the port as delivered.
This is the resin profile, not the metal BPC line: working pressure 0 to 1.0 MPa, vacuum down to -750 mmHg, proof pressure 1.5 MPa and a temperature window of -20 to +70 C. Because 12 mm is the top of the PC tube ladder, this fitting is the natural hand-off point between a machine's main 1/4 inch supply ports and its fatdest actuation lines, where a smaller connector would choke the bore.

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 PC1203 Is Used
Pneumatic press and clamp cylinders
Feeding a large-bore clamping cylinder on a stamping or press fixture: the 12 mm bore keeps supply losses low on short, high-consumption strokes, while the 1/4 inch PT stud lands directly on the valve manifold port.
Packaging machine main drop
Tapping the 1/4 inch PT port on a packaging machine's air preparation block and running a Dia 12 soft nylon line out to rotary actuators and heavy grippers along the line.
Valve island supply stub
Connecting a Dia 12 feeder tube to the 1/4 inch supply port of a solenoid valve island, where the pre-applied thread sealant saves a taping step during panel build.
Is the Airtac PC Threaded Straight Connector PC1203 the Right Part?
Sized both ways: step the thread down to PC1202 (1/8 inch PT) when the port is a small valve outlet, though an 1/8 inch thread on a 12 mm tube leaves the restriction at the port; step up to PC1204 (1/2 inch PT) for large manifold ports where the thread should not be the bottleneck. If the feed is from a Dia 10 mm line instead, PC1003 keeps the same 1/4 inch thread on the smaller bore. Tube OD must match exactly - a Dia 12 chuck will not seal on 1/2 inch (12.7 mm) imperial hose, which is a near-miss worth checking before ordering.
Match the thread to the port size on the valve or cylinder, not to the tube: the 1/4 inch PT stud with factory sealant suits standard manifold and regulator ports. For a line that passes through a panel wall, the PM bulkhead union or PLM bulkhead male elbow in Dia 12 (M22x1 locknut) is the shape to reach for instead.
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 PC1203 FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. It accepts one Dia 12 mm soft nylon or polyurethane tube and has a 1/4 inch PT male thread with sealant pre-applied.
No. AirTAC ships the PC1203 with sealant already on the 1/4 inch PT stud, so it screws straight into the port. On smaller M5 sizes in the same series a sealing gasket is used instead, but at 1/4 inch the sealant is the intended method. Grip the hex while tightening rather than twisting the POM release button, and confirm the tube is pushed home past the chuck before pressurising.
