About the Airtac PLM Right Angle Bulkhead Fitting PLM12
The PLM12 is AirTAC's bulkhead male elbow from the resin one-touch family, built for Dia 12 mm tubing. It mounts through a panel or enclosure wall: the fitting body passes through the hole and an M22x1 locknut, sized specifically for the Dia 12 frame, clamps it tight from the far side. Both tube ports take 12 mm push-in connections, so the line crosses the barrier and turns without a separate elbow or bulkhead union. To connect, push the tube fully home; the stainless spring gasket and chuck grip it. Press the POM release ring to free it.
This is the standard resin spec profile, not the metal line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa and a temperature window of -20 to +70 C. Use soft nylon or polyurethane tubing only. Internals are a POM release button and chuck, an aluminium-alloy guide, a stainless spring gasket and an NBR O-ring, with PBT on the moulded body sections.

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 PLM Right Angle Bulkhead Fitting PLM12 Is Used
Control cabinet air pass-through
Feeding a 12 mm main air line from the plant ring main into a sealed electrical cabinet: the PLM12 crosses the enclosure wall in one fitting and the M22x1 locknut seals the hole, keeping a single penetration instead of a bulkhead union plus an elbow.
Pneumatic clamping on a machining fixture
A Dia 12 supply line turning 90 degrees into the fixture plate of a CNC machining centre. The elbow shape removes a right-angle bend in stiff 12 mm tubing that would otherwise kink or fight the clamp cylinder port.
Vacuum sheet handling on a nesting table
Routing a 12 mm vacuum line from the pump side of a CNC nesting table to the suction manifold. The -750 mmHg (10 Torr) negative pressure rating covers the vacuum draw, and the bulkhead mount keeps the line fixed where it crosses the table frame.
Is the Airtac PLM Right Angle Bulkhead Fitting PLM12 the Right Part?
The only step below the PLM12 is the PLM10. Stepping down to Dia 10 changes two things at once: the bore gets smaller, so the carrying capacity of the line drops, and the panel nut changes from M22x1 to M20x1 - so the panel cut-out shrinks too. There is no size above Dia 12 in this family; 12 mm is the largest bore the PLM series is offered in, so if you need more capacity the answer is a parallel line, not a bigger fitting.
Both push-in ports are Dia 12 only, and they will not reliably grip 10 mm or 1/2 inch tube. Measure the tube outside diameter, not the nominal size, before ordering.
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 PLM Right Angle Bulkhead Fitting PLM12 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a working temperature range of -20 to +70 C. The tube ports are Dia 12 mm push-in, and the bulkhead locknut thread is M22x1. Tubing must be soft nylon or polyurethane.
No. Both ports of the PLM12 are machined for exactly Dia 12 mm outside diameter tube; a mixed connection will not seal. If your line steps down, terminate the 12 mm run at a different fitting and continue in Dia 10. Also note the panel hardware differs by size: the Dia 12 bulkhead uses an M22x1 locknut, while the PLM10 below it uses M20x1, so panel cut-outs are not interchangeable between the two.
