About the Airtac PM Panel Mount Straight Coupling PM12
The PM12 is an AirTAC PM series bulkhead union, a tube-to-tube one-touch fitting with no air-side thread at all. It joins two runs of Dia 12 mm soft nylon or polyurethane tubing across a panel or enclosure wall and is clamped by a single M22x1 locknut. Push each tube home and the internal chuck grips it against a stainless spring gasket; press the release collar and the tube slides straight back out.
This is the standard resin one-touch profile, not the metal BPC family: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa and a temperature window of -20 to +70 C. The release collar and chuck are POM over an aluminium-alloy guide with an NBR O-ring, supplied in the standard grey finish. Because there is no threaded port, no sealant or gasket is needed on the tube side - the locknut does all the work.

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 PM12 Is Used
Control cabinet pass-through
Mount the PM12 through the side wall of a machine control cabinet so a gripper or air-blast circuit fed inside the enclosure can reach a blow-off nozzle outside, without unscrewing a single fitting.
Flow-wrapper guard feed
Take the Dia 12 actuator line on a horizontal flow-wrapper through the sheet-metal guarding at the rotary jaw station, keeping the push-in connection accessible from outside for fast tube changes during film roll changes.
Laser cell assist-air panel
Bulkhead the assist-air drop feeding the solenoid bank of a CO2 laser cutting cell through the cell skin, so the 12 mm trunk line terminates neatly at the panel instead of trailing through the cable duct.
Is the Airtac PM Panel Mount Straight Coupling PM12 the Right Part?
PM12 sits at the very top of the PM ladder. The only neighbour is PM10 one step down, which shrinks the locknut to M20x1 and the bore with it - handy for tighter panel cutouts but it surrenders flow headroom on the same circuit. There is no larger union in this catalogue, so any line bigger than 12 mm needs a different series entirely. Match the tube OD exactly: a 12 mm chuck will not seal 1/2 in tubing, which measures roughly 12.7 mm across. If your wall pass-through needs a threaded leg on one side instead of two tube tails, that is the PMF bulkhead connector, not this part.
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 PM12 FAQ
The PM12 is a PM series bulkhead union for Dia 12 mm soft nylon or polyurethane tube, secured in the panel by an M22x1 locknut. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it holds vacuum to -750 mmHg (10 Torr), proof pressure is 1.5 MPa and the operating temperature range is -20 to +70 C. It is the grey resin version of the one-touch line.
No. The chuck is cut for exactly 12 mm outside diameter tubing and 1/2 in nominal tube measures about 12.7 mm, so it will neither seat nor seal. Use true 12 mm OD polyurethane or soft nylon, and remember the fitting carries no air-side thread - it is strictly tube-in, tube-out with the M22x1 locknut holding it in the wall.
