About the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF1203
The AirTAC PMF1203 is a bulkhead connector from AirTAC's resin one-touch range. It passes a Dia 12 mm tube connection through a panel or enclosure wall and finishes on the outside with a 3/8in PT male thread. Push the tube into the chuck until it bottoms out and the stainless spring gasket grips it for a pressure-tight joint; press the POM release ring and the tube slides free for rework.
This is the standard resin spec profile, not the metal BP line: working pressure 0-1.0 MPa, vacuum to -750 mmHg, proof pressure 1.5 MPa and a temperature window of -20 to +70 C. The 3/8in thread arrives with sealant already applied, and the bulkhead locknut on the Dia 12 size is M22x1, so drill the panel to suit and clamp the body from the outside.

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 PMF1203 Is Used
Bottling line control cabinet
Mount the PMF1203 through the cabinet wall of a filling machine so air distribution stays inside the panel while 12 mm drops feed gripper cylinders on the outside.
Packaging machine guard pass-through
Take a Dia 12 supply through the fixed guard of a carton erector and land the 3/8in thread on a rotary actuator outside the guarded zone, keeping pneumatics serviceable without opening the guard.
Plating line process enclosure
Where a fume hood or rinse enclosure wall separates the dry side from the wet side, the bulkhead body keeps the PBT fitting and 12 mm nylon line on the clean side of the sheet.
Is the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF1203 the Right Part?
Step down to PMF1003 if your circuit runs Dia 10 mm tube on the same 3/8in port; the bore is smaller, so expect lower flow to the actuator. Dia 12 mm is the largest tube the PMF family takes, so there is no step up in tube - if the port allows it, PMF1204 on a 1/2in thread is the alternative at the same bore. Bulkhead is the right shape when the tube side and the threaded side live on different sides of a sheet-metal wall. Match the thread to the port pitch, not to habit: a 3/8in PT stud will not seal into a 1/2in tapped hole. And keep the tubing exact - a Dia 12 chuck will not hold 1/2in hose even though the numbers look close.
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 PMF1203 FAQ
The PMF1203 is a resin one-touch bulkhead connector for Dia 12 mm tubing with a 3/8in PT male thread. Working pressure is 0-1.0 MPa, negative pressure reaches -750 mmHg, proof pressure is 1.5 MPa and the operating temperature range is -20 to +70 C. It suits soft nylon or polyurethane tube, the locknut thread for the Dia 12 size is M22x1, and the threaded end is supplied with sealant applied.
Drill the panel for the M22x1 locknut, insert the fitting body from inside, thread the locknut on from the outside and tighten until the body is clamped square to the sheet; the thread arrives pre-coated with sealant, so no extra tape is needed on the 3/8in stud. The chuck grips only the size it is built for - Dia 12 mm - so a 1/2in or 10 mm tube will not seal. If your line is Dia 10 mm, order PMF1003 instead.
