About the Airtac PC Threaded Straight Connector PC1201
The PC1201 is an AirTAC PC series one-touch male connector, the straight threaded fitting that turns a 1/8in PT male stud into a push-in socket for Dia 12 mm soft nylon or polyurethane tubing. Push the tube home and the stainless spring gasket plus the POM chuck grip the OD from the inside; press the release ring and the tube slides straight back out. No tools, no ferrules, no re-tightening after vibration.
This is the resin and brass one-touch profile, not the metal BP line: working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum to -750 mmHg, and a temperature window of -20 to +70 C. The body is brass and the 1/8in stud arrives from the factory with thread sealant already applied, so the stud goes straight into the port without an extra wrap of PTFE tape. Standard colour is grey; a D suffix on other PC codes changes only the release button, never the body.

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 PC1201 Is Used
Cylinder feed on compact machine frames
A pneumatic cylinder with a small 1/8in port often has to be fed by a long 12 mm main run to keep pressure drop low across the machine. The PC1201 bridges that mismatch at the port, and the pre-sealed stud means the joint holds without thread tape working loose under vibration.
Vacuum pick-and-place drop lines
Vacuum generators and ejectors rated around -750 mmHg suit this fitting's negative-pressure ceiling. On a packaging or cartoning head, large-bore 12 mm tube keeps the suction line's flow resistance down between the ejector and the suction cup, with fast release when cups are swapped.
Blow-off nozzles on conveying lines
Air-knife and blow-off stations on food or bottling conveyors typically run wide 10-12 mm tube from a compact manifold. A straight male connector at the manifold's 1/8in taps keeps the run neat, and the push-in socket lets maintenance re-route the jet without cutting tube.
Is the Airtac PC Threaded Straight Connector PC1201 the Right Part?
On the 1/8in rung of the PC ladder, Dia 12 is the top of the range: PC1001 is the size below it with 10 mm tube, and there is no larger tube offered on a 1/8in thread in this series. If you are pushing more air than a 12 mm line on a 1/8in port can comfortably carry, the answer is usually to step the port, not the tube - PC1202 and PC1203 give you the same 12 mm tube on 1/4in and 3/8in threads respectively, with PC1204 covering 1/2in ports. The full PC table runs M5 down to Dia 4 and 6 for reference.
Match the stud to the port thread exactly - a 1/8in PT stud will not seal properly in a 1/4in hole even with generous sealant. And remember the tube side is unforgiving in the other direction: a Dia 12 chuck will not hold 1/4in (6 mm) tube, so the OD you order must be the OD you run. If you need to pass this connection through a panel wall instead, the PLM bulkhead male elbow in Dia 12 uses an M22x1 locknut on the far side.
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 PC1201 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. It accepts Dia 12 mm soft nylon or polyurethane tube on a 1/8in PT male thread, with a brass body, POM chuck and release button, aluminium-alloy guide and NBR O-ring.
No. AirTAC ships the threaded stud with sealant already applied, so it seals in a 1/8in PT port as supplied; extra tape can actually reduce thread engagement. Only M5 sizes in this catalogue use a sealing gasket instead. On the tube side, make sure the cut is square and deburred so the chuck and spring gasket seat evenly on the OD.
