About the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF1204
The PMF1204 is an AirTAC PMF bulkhead female connector, the one-touch fitting made to be mounted through a panel or machine wall. On the tube side it grips 12 mm OD soft nylon or polyurethane tubing; on the air side it presents a female 1/2in PT internal thread that receives a male threaded stud, nipple or adaptor of your choice. The 12 mm tube size uses an M22x1 locknut, which is the largest panel nut in the PMF ladder, so check the mounting hole before ordering.
Installation is a two-step job. Drill the panel, pass the threaded body through, and secure it with the M22x1 locknut so the fitting becomes a fixed, wrench-proof air outlet. Then push the 12 mm tube straight into the chuck until it bottoms out: the stainless spring gasket and POM chuck grip the tube, and pressing the release ring frees it again. This is the resin one-touch profile: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C service, with a PBT body on a brass stud and sealant pre-applied to the mating thread faces.

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 PMF Female Thread Bulkhead Straight Through Fitting PMF1204 Is Used
Valve manifold outlet on a machine wall
Bolt the PMF1204 through the side plate of a press or assembly station and pick up air with a male PT stud on the manifold side, feeding 12 mm hose out to a large-bore clamp cylinder.
Packaging machine bulkhead supply
On a form-fill-seal or cartoning line, a female bulkhead port lets maintenance swap external hose runs without opening the guard, since the 1/2in fitting stays fixed in the M22x1 nut.
Control cabinet air distribution point
Use the threaded body as a pass-through on an electrical enclosure boundary, taking 12 mm line air in from the pneumatic side and breaking it out on a hinged door or rear panel.
Is the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF1204 the Right Part?
Dia 12 is the top of the PMF tube range - there is no larger tube size in this catalogue, so size down to PMF1003 if your run is Dia 10 and the flow demand is modest. On the thread side, 1/2in is also the largest port offered; the step below is 3/8in (PMF1203), which suits smaller valve outlets while keeping the same 12 mm tube and the same M22x1 panel nut. Because this is the female version, match it to a male PT stud: a male-threaded bulkhead (the PM series) is the alternative if you want to screw a hose tail or speed controller straight on.
Tube OD must match exactly. The 12 mm chuck will not seal or hold 1/4in (approximately 6.3 mm) hose, and no adapter exists for that; if your spool of tube is imperial, change the fitting, not the insert.
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 PMF Female Thread Bulkhead Straight Through Fitting PMF1204 FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum to -750 mmHg, proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting takes Dia 12 mm OD soft nylon or polyurethane tube on one side and has a 1/2in PT female thread on the other, with an M22x1 locknut for the bulkhead mounting.
Any male PT stud, nipple or adaptor with a 1/2in thread - for example a hose tail, speed controller inlet or gauge stub. PT is a taper thread, so the mating male part should carry its own sealant or tape; the PMF1204 itself arrives with sealant where the catalogue specifies it, and the tube-side joint needs none because the chuck and O-ring make the seal.
