About the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF1004
The AirTAC PMF1004 is a PMF bulkhead connector, AirTAC's female-threaded one-touch fitting built to be mounted through a panel or machine wall. It takes Dia 10 mm soft nylon or polyurethane tube on the tube side and presents a 1/2in PT female port on the other side of the bulkhead, so the air connection can be made from outside the enclosure without opening it.
Installation is the standard one-touch action: push the 10 mm tube into the chuck until it bottoms, and the stainless spring gasket and POM chuck grip it under a NBR O-ring seal; press the release ring to free it. As a threaded resin-series part it is rated 0 to 1.0 MPa (0 to 10 kgf/cm2), withstands 1.5 MPa proof pressure, handles -750 mmHg vacuum and works from -20 to +70 C. The body is PBT with a brass stud, and the 1/2in thread arrives with sealant already applied.

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 PMF1004 Is Used
Control panel pass-through on a packaging line
Mount the PMF1004 through the wall of a packaging machine's electrical cabinet so a Dia 10 mm feed line outside connects to 1/2in plumbing inside without opening the enclosure during changeover.
Water treatment pneumatic distribution board
On a plant air distribution board feeding diaphragm pump pilots, the bulkhead style keeps the wet 10 mm tubing outside the panel and the sealed 1/2in PT connections inside where they stay clean and inspectable.
Conveyor gate cylinder feed at a guarded frame
Bring a Dia 10 mm nylon line through the sheet-metal guard of a conveyor gating station and land it on a 1/2in female port for the gate valve circuit, with the M20x1 locknut holding the fitting rigid against tube pull.
Is the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF1004 the Right Part?
Dia 10 mm is the second-largest tube size in this family. Stepping down to Dia 8 gives you a slimmer hose run and an M16x1 bulkhead locknut instead of the M20x1 nut this fitting uses; stepping up to Dia 12 buys more flow capacity for a main drop at the cost of a stiffer, harder-to-route tube. Both neighbours exist on this thread, so check the actuator's port size before committing. Do not assume a 10 mm fitting will hold 3/8in imperial tube - 3/8in OD is about 9.5 mm and will leak or blow out; the tube OD must match exactly.
Pick PMF over a plain threaded connector when the port lives behind a sheet-metal wall: drill the panel, pass the brass stud through, secure it with the locknut, and the PBT female thread faces the outside world. If you need the female thread on the tube side instead, that is a different shape entirely.
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 PMF1004 FAQ
This is a resin-series bulkhead female connector: Dia 10 mm tube on the one-touch side and a 1/2in PT female thread on the bulkhead side, sealed by an M20x1 locknut. Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and operating temperature -20 to +70 C. It runs on soft nylon or polyurethane tube. The PBT body carries a brass stud; the thread ships with sealant applied.
Drill the panel to clear the brass stud, insert the fitting from the inside, and secure it with the hex locknut on the outside - for Dia 10 mm that locknut thread is M20x1, which tells you the minimum clearance you need beyond the stud itself. Keep the panel thickness within what the stud length allows and avoid over-compressing the gasket faces. Once mounted, the female PT thread sits on the outer face while the tube chuck stays accessible on the inner face.
