About the Airtac PC Threaded Straight Connector PC1201D
The PC1201D is an AirTAC PC series one-touch male connector, the largest tube size offered on this body: it pushes a Dia 12 mm soft nylon or polyurethane line onto a 1/8 inch PT male thread. To make the joint you press the tube straight into the chuck until it bottoms out, the stainless spring gasket and POM chuck grip it against pressure and vacuum, and pressing the release ring lets it pull free again without tools.
This sits in the resin and brass spec profile, not the metal BPC line: working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum down to -750 mmHg (10 Torr) and a temperature window of -20 to +70 C. The body is brass with a PBT threaded section, the release button and chuck are POM, and the seal is an NBR O-ring. Two details worth knowing before you order: the trailing D on a PC code changes only the release button to black - the body and every dimension stay identical to the grey PC1201 - and the 1/8 inch thread arrives with sealant already applied, so it seals straight into a PT port.

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 PC1201D Is Used
Injection moulding clamp circuits
A Dia 12 nylon run from a 1/8 inch valve outlet keeps clamp cylinders on a moulding press charging quickly; the 1.0 MPa ceiling matches a standard shop-air regulator.
Palletiser gripper supply trunk
Use it as the trunk take-off feeding a palletiser's vacuum ejector bank - the fitting itself is rated to -750 mmHg, so it survives the vacuum side of the circuit.
Bottling line valve manifold outlets
Push a Dia 12 polyurethane drop straight off a 1/8 inch PT manifold port on a filler's valve island; the pre-applied thread sealant removes the paste-and-tape step on the bench.
Is the Airtac PC Threaded Straight Connector PC1201D the Right Part?
On the PC ladder with a 1/8 inch thread, Dia 12 is the top rung - PC1001 (Dia 10) is the only step below it, and nothing larger exists on this thread. Stepping down to PC1001 buys a slimmer profile where the 10 mm line already carries the demand; staying at Dia 12 keeps the full bore for a long or high-demand run. If your port is a 1/4, 3/8 or 1/2 inch, the same Dia 12 tube carries over on PC1202, PC1203 and PC1204 - a bigger thread does not add tube capacity here, it only matches the port. And where the line has to turn at the valve, PL1201 (male elbow) handles the same Dia 12 tube on the same 1/8 inch thread.
The chuck size is fixed: this fitting grips exactly Dia 12 mm tube. It will not hold 10 mm, 13 mm or 1/2 inch nominal hose, so confirm the tube outer diameter before ordering.
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 PC1201D FAQ
It is a PC one-touch male connector for Dia 12 mm tube with a 1/8 inch PT male thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, negative pressure to -750 mmHg (10 Torr), operating temperature -20 to +70 C. Tubing must be soft nylon or polyurethane of exactly Dia 12 mm.
No. On the PC series the D suffix changes only the release button colour to black; the brass body, dimensions, grip and ratings are identical, so the two are interchangeable in any Dia 12 x 1/8 inch position.
