About the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF803D
The PMF803D is an AirTAC PMF bulkhead connector in black, a one-touch female fitting made to pass through a panel or machine wall. It joins Dia 8 mm soft nylon or polyurethane tube on the tube side and presents a 3/8in PT female thread on the side you wire up. Push the tube into the chuck until it bottoms out and the stainless spring gasket grips it; press the POM release ring and the tube slides free again.
This is the resin one-touch profile: 0 to 1.0 MPa working pressure (0-10 kgf/cm2), -750 mmHg vacuum, 1.5 MPa proof pressure and a service window of -20 to +70 C. The 8 mm size seals through an M16x1 bulkhead locknut, and the female 3/8in port lets you bolt the air supply on from outside the enclosure with a standard male stud, so no fitting has to be threaded through a tight panel cutout.

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 PMF803D Is Used
Control cabinet pass-through
Mounted through the wall of an electrical enclosure on a packaging line, the PMF803D carries a Dia 8 mm feed to the valve manifold outside while the 3/8in female port is connected from the plant air side, keeping hands out of the live cabinet.
Vacuum tray-sealing machine
On a food tray sealer running -750 mmHg vacuum lines to the lid frame, the black 8 mm bulkhead body sits flush on the stainless guard plate and its POM release ring lets maintenance swap vacuum tube without tools.
Electronics wash-station panel
A PCB cleaning station routes Dia 8 mm rinse-air tubing through its rear bulkhead via the M16x1 locknut, and the black body hides against the dark panel where a standard grey fitting would stand out.
Is the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF803D the Right Part?
On the tube ladder around this SKU, PMF603 drops the bore to Dia 6 mm for lighter lines such as pilot signals, and PMF1003 opens it to Dia 10 mm where a downstream cylinder or vacuum ejector wants more volume at the same 3/8in thread. If the port itself is the constraint, the thread steps are PMF802 at 1/4in and PMF804 at 1/2in, both still taking Dia 8 mm tube. Match the tube OD exactly: a Dia 8 chuck will not seal on 5/16in or 10 mm tube, so measure before you order.
Choose PMF over a plain PC male stud when the fitting has to live on both sides of a sheet-metal wall and you want the threaded connection reachable without reaching inside the cabinet. Note that the threaded half arrives with factory sealant, so no PTFE tape is needed on the 3/8in port.
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 PMF803D FAQ
Working pressure 0 to 1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa and a temperature range of -20 to +70 C. This SKU takes Dia 8 mm soft nylon or polyurethane tube on a 3/8in PT female thread, and the bulkhead hole is sealed by an M16x1 locknut.
The 8 mm size clamps with an M16x1 locknut, so drill the bulkhead hole for that thread and check the panel is thin enough for the locknut to engage fully. The 3/8in female thread arrives from AirTAC with sealant already applied, so additional PTFE tape is unnecessary and excess tape can sit in the air path.
