About the Airtac PCF Female Thread Straight Fitting PCF1204
The PCF1204 is an AirTAC PCF one-touch female connector: a tapped 1/2 inch PT female port on one end, a Dia 12 mm push-in socket on the other. The female thread lets you screw the fitting straight onto a machined port or manifold boss without an intermediate nipple, and the thread arrives from AirTAC with sealant already applied, so in most cases no extra tape is needed before assembly.
Connection takes seconds: cut the tube square, push it into the socket until it bottoms, and the internal chuck grips the OD while the stainless spring gasket and NBR O-ring close the seal. Press the POM release ring toward the body and the tube slides free. This is the resin/brass spec profile: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, -20 to +70 C. At 12 mm this is the big-bore end of the range, where flow capacity follows the wide tube bore rather than any published figure.

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 PCF Female Thread Straight Fitting PCF1204 Is Used
Packaging machine manifold drops
Machines built with 1/2 inch PT tapped manifold ports feeding large clamp cylinders take the PCF1204 directly, with 12 mm soft nylon lines running out to the cylinders.
CNC fixture clamping circuits
A swing clamp or work-support circuit plumbed from a directional valve's 1/2 inch female outlet benefits from the wide 12 mm bore feeding high-volume clamping strokes.
Textile machine air distribution
Long 12 mm polyurethane runs to knitting and weaving machine air jets and blow-offs screw straight into tapped frames using this female-threaded push-in body.
Is the Airtac PCF Female Thread Straight Fitting PCF1204 the Right Part?
Dia 12 is the largest tube the ladder offers, so the only step from here is down: PCF1004 carries the same 1/2 inch female thread on a Dia 10 mm tube, which suits smaller cylinders and slightly stiffer routing. On the thread side, PCF1203 is the neighbouring choice with a 3/8 inch PT female port on the same 12 mm bore - drop to it when the tapped port on your manifold is 3/8 inch.
Match the thread to the port, not to habit: a 1/2 inch PT female connector belongs on a port actually tapped 1/2 PT. And be careful with the tube, not the thread: 1/2 inch imperial tubing measures about 12.7 mm OD and will not seal in this Dia 12 metric socket. The OD must match exactly. If you need the same connection to pass through a panel wall instead of sitting on a port, the bulkhead-shape PMF is the right answer rather than this one.
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 PCF Female Thread Straight Fitting PCF1204 FAQ
It is a PCF one-touch female connector joining Dia 12 mm tubing to a 1/2 inch PT female thread. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), it holds vacuum to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the working temperature range is -20 to +70 C. Soft nylon or polyurethane tube only.
Usually not. AirTAC ships the threaded parts of this range with sealant pre-applied to the thread, so the fitting normally seals straight into a 1/2 inch PT port as delivered. Avoid over-tightening into a cast manifold port, and remember the female thread is tapered PT - it is not a parallel G-thread and will not correctly mate with a BSPP port.
