About the Airtac PM Panel Mount Straight Coupling PM12D
The AirTAC PM12D is a PM bulkhead connector, the fitting built to carry Dia 12 mm soft nylon or polyurethane tubing through a panel or machine wall while keeping the connection serviceable from both sides. On the far side of the plate you slide the tube straight into the chuck; the stainless spring gasket and NBR O-ring seal it, the chuck grips under pressure, and pressing the POM release ring lets the tube out again. The 02 code in the part number is the 1/4in PT male stud that mates with your circuit on the inside face.
This is the resin and brass profile, not the metal line: working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum to -750 mmHg (10 Torr), and a service window of -20 to +70 C. The D suffix makes the body black instead of the standard grey, useful where a dark panel interior would make a grey fitting stand out. The threaded section is PBT with a brass stud, and it arrives with sealant already on the thread; the Dia 12 bulkhead nut underneath is M22x1, the largest locknut size in the PM range.

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 PM Panel Mount Straight Coupling PM12D Is Used
Control cabinet pass-through on a CNC router
Mount the PM12D through the cabinet wall so the Dia 12 main air line terminates outside with the valve manifold, keeping dust and chip load out of the electronics bay. The 1/4in stud suits the manifold inlet directly.
Packaging machine guard plate feed
Route the Dia 12 supply to a horizontal flow-wrapper's pneumatic section through the sheet-metal guard. Service from either side without cutting the tube, and the black body blends into painted guarding.
Bulkhead feed for a bottling line valve island
Take a Dia 12 drop from the plant ring main through the frame of a rotary filler and finish on a 1/4in PT port at the valve island. The M22x1 locknut carries the load so the tubing never bears panel weight.
Is the Airtac PM Panel Mount Straight Coupling PM12D the Right Part?
Step down one tube size and the PM10 gives you the same panel-through shape on Dia 10 tube, but the locknut changes from M22x1 to M20x1, so drill the panel hole for the nut you will actually buy. Dia 12 is the top of the PM ladder - there is no larger bulkhead in this catalogue, so if your circuit needs Dia 16 you are on the wrong page entirely. Before ordering, check the port you are feeding: a 1/4in PT stud threads directly into standard valve and cylinder ports, and if your manifold is tapped 3/8in or 1/2in you should move to a larger code rather than chase an adapter.
One rule dominates every one-touch purchase here: tube OD must match the fitting exactly. A Dia 12 chuck will not seal on 1/2in (12.7 mm) imperial hose, and nothing in this catalogue is sized for it - buy soft Dia 12 metric tubing or the joint will leak.
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 PM Panel Mount Straight Coupling PM12D FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), proof pressure 1.5 MPa, vacuum down to -750 mmHg (10 Torr), operating temperature -20 to +70 C. It accepts Dia 12 mm soft nylon or polyurethane tube, has a 1/4in PT male thread with pre-applied sealant, and its bulkhead locknut thread is M22x1.
No. The chuck and seal are cut for a 12 mm outside diameter and nothing else; undersized tube will not seat in the spring gasket and the joint will leak under pressure. Use a PM10 for Dia 10 tube - note its locknut is M20x1, so your panel hole and nut change with it. Match the tube to the code exactly.
