About the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF803
The PMF803 is an AirTAC PMF bulkhead connector, built to carry a Dia 8 mm pneumatic line through a panel or machine housing without unscrewing anything at either end. The threaded stud passes through a drilled hole and is clamped by its locknut, so the fitting itself becomes part of the wall. AirTAC specifies an M16x1 locknut thread for the Dia 8 size, which tells you the panel opening you need before you ever pick up a drill bit.
One-touch action on each end: push the soft nylon or polyurethane tube home and the internal chuck grips it; press the POM release ring and it slides free. This is the resin and brass spec profile, not the metal line - working pressure 0 to 1.0 MPa, vacuum down to -750 mmHg, proof pressure 1.5 MPa, and a temperature range of -20 to +70 C. The thread is PT and arrives with sealant already applied, so the 3/8 in port seals on assembly without extra tape.

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 PMF803 Is Used
Control cabinet pass-through
Feed a 3/8 in supply from the air preparation station outside an electrical enclosure to the valve manifold inside, with the PMF803 locked through the cabinet wall and its M16x1 nut doing the sealing against the sheet metal.
Pick-and-place machine housing
Mount the connector through the base plate of a pick-and-place gantry so vacuum ejector lines can be disconnected from outside the machine envelope without reaching behind guarded internals.
Packaging machine utility wall
On a form-fill-seal wrapper, run Dia 8 cylinder supply lines through the frame side panel in a neat row of bulkhead connectors, keeping all air plumbing accessible from the operator side for changeover.
Is the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF803 the Right Part?
Step down to PMF603 (Dia 6) when the line feeding the panel only needs a lighter bore, or up to PMF1003 (Dia 10) if flow demand on the far side is the constraint - capacity rises with the tube bore, and AirTAC publishes these parts as a characteristic curve rather than a single flow number. Match the 3/8 in PT thread to the port you are connecting on the outside; stepping it with a bushing works, but a direct thread match keeps the stack-up short.
Choose the PMF bulkhead over a PLM bulkhead male elbow when you want a straight male thread on the external side rather than an elbow. Whatever you pick, the tube OD must match exactly: a Dia 8 connector will not seal on 5/16 in or 10 mm tube, no matter how close it looks.
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 PMF803 FAQ
It is an AirTAC PMF bulkhead connector for Dia 8 mm soft nylon or polyurethane tube with a 3/8 in PT male thread. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure goes to -750 mmHg, proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. The bulkhead locknut thread for the Dia 8 size is M16x1.
Drill a panel hole to suit the M16x1 locknut, pass the threaded stud through, and tighten the nut from the inside so the grey body clamps the wall. Tube on both ends must be soft nylon or polyurethane of exactly 8 mm OD - polyurethane is more forgiving to insert, nylon holds shape better in long runs. At elevated ambient temperatures the tubing, not the fitting, is usually the first thing to reach its limit.
