About the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF1203D
The PMF1203D is an AirTAC PMF bulkhead connector in the black (D suffix) finish. It joins Dia 12 mm soft nylon or polyurethane tubing to a 3/8 in PT male thread and is built to pass through a panel, cabinet wall or machine guard: the threaded stud goes through the hole, the supplied locknut (M22x1 on Dia 12) clamps it from the far side, and the push-in port sits where your hand can reach it. Push the tube home and the chuck plus stainless spring gasket grip it for a sealed joint; press the POM release ring to free it again.
This is the resin one-touch family, not the metal line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa and a service temperature of -20 to +70 C. The PBT body in this code is black rather than the standard grey, the stud is brass, and the thread arrives from the factory with sealant already applied, so it seals straight into a PT tapped 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 PMF Female Thread Bulkhead Straight Through Fitting PMF1203D Is Used
Control cabinet pass-through on a packaging machine
Mount the PMF1203D through the cabinet wall so the 3/8 in threaded side stays among the valves and the Dia 12 push-in port sits outside, letting a main air line enter the enclosure without drilling a second grommet or opening the door for service.
Wash-side feed on a bottling conveyor
Where spray water reaches the machine frame, the black PBT bulkhead body and the panel-clamped M22x1 locknut keep the Dia 12 tube junction accessible and clear of pooled water, with the release ring reachable for quick hose changes during changeover.
Fixture clamping line on a machining cell
A Dia 12 trunk feeding clamp cylinders on a jig table can terminate inside the guard: bulkhead-mount this fitting at the guard panel, run the 3/8 in PT side to the supply, and swap clamp hoses at the push-in port without pulling the panel.
Is the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF1203D the Right Part?
On tube size, Dia 12 is the top of the PMF ladder - there is no larger step, so the only neighbour is PMF1003 one size down at Dia 10 mm, which drops the locknut thread to M20x1 and suits lighter lines such as single-cylinder feeds. On thread, the 3/8 in port sits between the 1/4 in (02) and 1/2 in (04) versions; match it to the tapped port on your valve manifold or FRL outlet rather than adapting up with bushings. If you need to change tube diameter at the wall, this shape will not do it - step to a reducer family instead, because a PMF port holds its one tube size only, and a Dia 12 port will not reliably grip 1/2 in (12.7 mm) imperial tube pushed in by mistake.
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 PMF1203D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting joins Dia 12 mm soft nylon or polyurethane tube to a 3/8 in PT male thread, carries an M22x1 bulkhead locknut, and is supplied in the black D-suffix finish from the resin one-touch series.
No. The PMF resin line is rated to +70 C maximum; the 0 to +150 C rating belongs to AirTAC's separate metal BPC family and comes with a lower 0.9 MPa working pressure. If your panel sits near an oven or steam line, check the local ambient first - above 70 C the resin body and NBR seal are the limits, and the tubing itself will usually fail even earlier.
