About the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF1004D
The PMF1004D is an AirTAC PMF bulkhead connector in the black D finish, sized for Dia 10 mm soft nylon or polyurethane tube on the thread side and a 1/2in PT male port on the other. Its job is to carry a 10 mm air line through a hole in a panel, enclosure wall or machine frame: the threaded stud passes through, the locknut (M20x1 for Dia 10) clamps it to the wall, and the one-touch chuck on the outside face accepts the tube.
Connection is the standard resin one-touch action - push the tube straight in until it bottoms, the stainless spring gasket and chuck grip it against the NBR O-ring, and pressing the POM release ring frees it again. This is the resin/brass profile: 0-1.0 MPa working pressure, -750 mmHg vacuum capability, 1.5 MPa proof pressure and -20 to +70 C. Because this is a D-suffix part outside the PC/POC families, the black finish applies to the body itself, not just the button. The 1/2in thread arrives with sealant already applied, so it is ready to thread into the 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 PMF1004D Is Used
Control cabinet pass-through
Take a Dia 10 supply line from inside a packaging machine's electrical cabinet to an outside valve manifold without drilling a ragged grommet hole - the PMF1004D studs through the cabinet wall and the M20x1 locknut holds it square against the sheet.
Clamp circuit on a press fixture
Feed the larger-bore clamp cylinder on a pneumatic press fixture through the fixture's mounting plate; the 1/2in PT stud suits big port blocks and the 10 mm bore keeps pressure drop low on short, high-volume clamp strokes.
Vacuum line into a test chamber
Route a pick-and-place vacuum line rated to -750 mmHg through the side wall of a benchtop test enclosure, keeping the release button accessible outside the chamber for fast tube changes between test runs.
Is the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF1004D the Right Part?
You are on the large end of this ladder. Down one step, PMF1003 pairs the same Dia 10 tube with a 3/8in PT stud when the port is smaller; up one step, PMF1204 takes Dia 12 tube on the same 1/2in thread when the line is bigger. Dia 10 is also the last size before Dia 12, so there is no larger tube option in this series. Match the tube OD exactly - a Dia 10 chuck will not seal 3/8in imperial tube, which is fractionally smaller at roughly 9.5 mm, and it will not hold 12 mm tube either.
Pick a bulkhead shape when the air path has to cross a boundary the tube cannot cross neatly - a control cabinet wall, a vacuum-forming platen edge, a guard panel. If both ends of the joint live on the same side of the wall, a straight PC or an elbow PL is the simpler answer; PMF earns its place only where a through-panel, nut-fixed joint is needed.
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 PMF1004D FAQ
It joins Dia 10 mm soft nylon or polyurethane tube to a 1/2in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it holds vacuum down to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. The body is PBT in the black D finish with a brass stud, POM release button and chuck, aluminium-alloy guide, stainless spring gasket and NBR O-ring. The bulkhead locknut thread for Dia 10 tube is M20x1.
No. 3/8in tube measures about 9.5 mm OD, which is under the Dia 10 chuck's grip range, so it will leak or blow out - the tube OD must match the fitting size exactly; use a PG10-8 style reducer if you genuinely need to join 8 mm tube to this line. On the thread side, the 1/2in PT stud arrives with sealant pre-applied from the factory, so no additional tape or paste is needed for the first installation.
