About the Airtac PLM Right Angle Bulkhead Fitting PLM8
The PLM8 is an AirTAC PLM bulkhead male elbow, a one-touch fitting built to carry a Dia 8 mm tube through a sheet-metal panel and turn the flow 90 degrees on the far side. The fitting body passes through a drilled hole in the panel and the M16x1 locknut (the standard locknut for a Dia 8 part in this family) clamps it tight from behind, so the tube connection sits neatly on the outside while the plumbing continues inside.
Connection is classic one-touch: push the 8 mm soft nylon or polyurethane tube into the chuck until it bottoms, and the stainless spring gasket and POM chuck grip it for a sealed joint; press the POM release ring and the tube slides free for rework. This is the resin and brass profile, not the metal BP line: working pressure 0-1.0 MPa, vacuum down to -750 mmHg, proof pressure 1.5 MPa, and a service temperature of -20 to +70 C. Grey is standard, and the D suffix version changes the body colour to black on this series.

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 PLM8 Is Used
Control cabinet pass-through
Take the plant air feed through the back wall of a machine's electrical cabinet so the solenoid manifold inside stays sealed and the tubing lands on one tidy 8 mm drop.
Rotary indexing table guard
Route the clamp-cylinder supply through the sheet-metal guard of an indexing dial plate, keeping the tube joint outside the rotating zone where it can be inspected.
Laser cutter air assist
Pass an 8 mm assist-air line through the enclosure wall of a CO2 laser cutter to feed the cutting head, with the elbow keeping the bend tight against the housing.
Is the Airtac PLM Right Angle Bulkhead Fitting PLM8 the Right Part?
Sizing both ways within the PLM ladder: step down to PLM6 for lighter lines - the locknut shrinks to M14x1 and the bore feeds smaller actuators; step up to PLM10 for heavier demand, where the locknut grows to M20x1 and the panel hole must be drilled accordingly. The locknut thread changing with tube size is the detail installers forget: order the panel cut-out around it, not around the tube.
Tube OD must match exactly - a Dia 8 chuck will not seal on 5/16 inch or 6 mm tubing, and no adaptor inside the fitting fixes that. If your port is on the panel itself rather than passing through it, a PL male elbow screwed straight into the port is the simpler shape; PLM earns its keep only when the tube has to cross a wall.
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 PLM8 FAQ
It is a Dia 8 mm one-touch bulkhead elbow with an M16x1 locknut for panel mounting. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure is -750 mmHg, proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. It accepts soft nylon or polyurethane tubing only, and this is the resin and brass profile - not the 0.9 MPa / 150 C metal BPC family.
Drill the panel hole for the Dia 8 body, insert the fitting from the front, and run the M16x1 locknut up behind the panel to clamp it. Remember the locknut thread scales with tube size across the PLM range - M14x1 on Dia 6 and M20x1 on Dia 10 - so a mixed-size panel needs a different cut-out per fitting, and the 8 mm tube must be exactly 8 mm OD to seal in the chuck.
