About the Airtac PLM Right Angle Bulkhead Fitting PLM12D
The PLM12D is an AirTAC PLM bulkhead male elbow, a one-touch fitting that joins two Dia 12 mm tubes through a panel or machine wall. Push each tube home and the stainless spring chuck grips it; press the release ring and the tube comes free again without tools. The threaded body passes through a drilled hole and an M22x1 locknut clamps it to the panel, so the elbow sits where you can reach it while the line runs behind the sheet metal.
This is the resin and brass profile, not the metal BPC line: working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, temperature -20 to +70 C. Use soft nylon or polyurethane tube only. The body is PBT over a brass bulkhead stud, the chuck is POM and the O-ring is NBR. The D suffix on this SKU means the body is moulded in black rather than the standard grey, useful where the fitting is visible on dark machine framing.

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 PLM12D Is Used
Robot welding cell guard pass-through
Take the 12 mm supply and exhaust lines for a gripper manifold through the cell guard wall with the PLM12D, so the elbow stays reachable outside the guarded area while the tubing runs to the end-of-arm tooling.
Injection moulding cabinet bulkhead
Pass the main 12 mm drop line through the wall of a moulding machine's equipment cabinet and land it on a bulkhead elbow, giving the maintenance team a service point that does not require opening the panel.
Packaging line clamp circuit
Feed a large-bore clamp cylinder on a cartoning machine from behind the guard plate; the Dia 12 bore carries the volume the clamp needs, and the black body blends with dark anodised machine frames.
Is the Airtac PLM Right Angle Bulkhead Fitting PLM12D the Right Part?
Dia 12 is the top of the PLM ladder. The only step down that exists is Dia 10 (PLM10), which suits lighter branch lines and takes a smaller panel hole; there is no larger PLM, so heavier flows must move to a different family. Do not assume a 1/2 inch hose fits: 1/2 inch is 12.7 mm and the PLM12D socket is machined for 12.0 mm OD tube exactly. A mismatched tube either will not seat or will blow out under pressure.
Choose this shape when the line must cross a wall and turn 90 degrees on the far side. If the crossing is straight through, a PM bulkhead union is leaner; if the elbow can sit on a port instead of a panel, a standard PL male elbow avoids drilling altogether.
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 PLM12D FAQ
Working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting takes Dia 12 mm soft nylon or polyurethane tube on both sides and is secured through the panel by an M22x1 locknut thread.
No. A 1/2 inch hose measures about 12.7 mm OD, while this socket is made for 12.0 mm OD tube, and one-touch chucks only seal on the exact nominal size. Use soft nylon or polyurethane tube marked Dia 12; for a true 1/2 inch line you need a different fitting entirely.
