About the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF804D
The PMF804D is an AirTAC PMF bulkhead female elbow in the resin one-touch range, joining Dia 8 mm soft nylon or polyurethane tube to a 1/2in PT female port. The elbow body passes through a hole in a panel or machine wall, and a locknut - an M16x1 thread on the Dia 8 size - clamps it tight from the far side, so the tube side and the port side stay separated while the pneumatic circuit passes through.
As with every one-touch fitting in this catalogue, you push the 8 mm tube straight into the chuck until it bottoms out; the stainless spring gasket and POM chuck grip it for pressure and vacuum alike, and pressing the POM release ring lets it slide free for rework. The rating for this resin family is 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, and -20 to +70 C. The D suffix on this SKU gives a black body rather than the standard grey.

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 PMF804D Is Used
Passing air through a bottling line guard panel
Mount the PMF804D through the sheet-metal guard of a rotary bottle filler so the 8 mm tube run to a gripper cylinder stays outside the wash area, while the 1/2in PT port on the inside wall connects to a valve manifold with a gasket or sealant.
Control cabinet feed in a plastics injection shop
Use the female elbow to bring a Dia 8 vacuum or air line through the wall of an electrical enclosure on an injection moulding machine, keeping the resin elbow clear of hot manifolds thanks to the -20 to +70 C resin envelope and the black body.
Bulkhead port on a robot end-of-arm tooling plate
Tap a 1/2in PT hole in the tooling plate of a palletising robot arm, mount the PMF804D with its M16x1 locknut, and break the 8 mm tube run at the plate so the arm can be swapped without cutting tube.
Is the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF804D the Right Part?
This sits mid-ladder on tube size: step down to PMF6xx for 6 mm tube feeding lighter actuators, or step up to PMF10xx when the run carries the higher flow demand of a 10 mm bore circuit - both exist on the same 1/2in port if you want to keep the thread unchanged. On the thread side, 1/2in is the largest port the PMF female elbow range offers; the next step down is a 3/8in port (PMF803). Match the thread to the port already drilled and tapped in your panel, because the bulkhead nut does the clamping, not the thread.
One caution that saves returns: tube OD must match the fitting exactly. A Dia 8 PMF will not seal on 5/16in imperial tube even though the two look close, and it will not seal on 6 mm tube at all. If your wall is thin sheet rather than a thick panel, check the mounting hole against the M16x1 locknut 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 PMF Female Thread Bulkhead Straight Through Fitting PMF804D FAQ
It is a Dia 8 mm tube, 1/2in PT female thread bulkhead female elbow from AirTAC's resin one-touch range. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), it holds vacuum to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the working temperature range is -20 to +70 C. The panel-side locknut thread on the Dia 8 size is M16x1, and the D suffix specifies a black body.
AirTAC ships threaded one-touch parts with sealant already applied to the thread, so the 1/2in port connection is ready to make up as delivered. The tube side needs no sealant at all - the one-touch chuck and gasket seal the 8 mm tube on insertion, and the same release ring lets you pull the tube back out when the circuit changes.
