About the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF603D
The PMF603D is an AirTAC PMF bulkhead female connector, the panel-mount member of the resin one-touch family. It joins Dia 6 mm soft nylon or polyurethane tube to a 3/8 inch PT female thread, and the body passes through a panel or machine wall where the supplied locknut - an M14x1 thread on the Dia 6 size - clamps it in place. Because the front face is female, you fit a male-nosed device or adaptor to the exposed side after mounting, then push the tube into the back: the internal chuck grips the tube the instant it bottoms out, and a press on the release ring lets it slide free again.
This is the standard resin spec profile, not the metal line: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and a -20 to +70 C temperature window. The D suffix makes the body black as well as the release button, useful where colour-coding on the panel matters. Threaded parts are PBT with a brass stud and arrive with sealant already applied to the thread, so the female port seals on assembly without extra tape.

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 PMF603D Is Used
Rotary indexing table cabinet pass-through
Mount the PMF603D through the wall of a control cabinet on an indexing table, then plug a male-threaded drop hose into the female face each time the tooling plate is swapped.
Packaging conveyor guard service tap
Take a Dia 6 air feed through guarding at a reject-blower station on a carton line, so the tube can be released from behind and re-fed without opening the guard.
Maintenance bench drop
Fit the connector through the back panel of a repair bench so technicians plug a 3/8 inch male whip into the front face, while Dia 6 tube runs tidy inside the frame to the manifold.
Is the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF603D the Right Part?
Dia 6 sits mid-ladder. Step down to Dia 4 if the drop line feeds a small valve or pilot actuator and you want a slimmer bundle through the panel cut-out; step up to Dia 8 when the run after the wall carries a main feed rather than a branch. Whatever you choose, the tube OD must match exactly - a Dia 6 chuck will not seal on 1/4 inch tube, and the two sizes are close enough that a forced fit looks almost right until it blows off.
Match the female thread to whatever plugs into the front face: a 3/8 inch male nose on a regulator, gauge or hose union. If your panel hole is already drilled and you only need the air path through it with no external connection, the threaded PM bulkhead or the male-elbow PLM is the shape to compare against - PMF is specifically the version with the female port on the mounted face.
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 PMF603D FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a working temperature of -20 to +70 C. The tube size is Dia 6 mm for soft nylon or polyurethane, the thread is a 3/8 inch PT female port, and the bulkhead locknut thread is M14x1. The D suffix gives a black body and black release button.
The 3/8 inch female port sits proud on the mounted side, so you screw in any male-nosed item - a hose union, a gauge stem or a threaded plug to blank it off. AirTAC coats the thread with sealant at the factory, which seals the female port itself on assembly. The one-touch grip on the Dia 6 tube happens entirely on the back side, so front-side connections can be remade repeatedly without disturbing the tube circuit behind the panel.
