About the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF801
The PMF801 is an AirTAC PMF bulkhead connector in the resin one-touch range: a Dia 8 mm tube lands on the push-in side, and the 1/8in PT female thread on the far side stays available for a threaded take-off after the fitting has been bolted through a panel. The fitting passes through the wall, the locknut pulls it tight, and your pneumatic circuit is divided cleanly into two sides.
To make the connection, push the soft nylon or PU tube straight into the chuck until it bottoms out - the stainless spring gasket and POM chuck grip it under spring load, no tools. Press the release ring to free it. This is the resin/brass spec profile, not the metal line: 0 to 1.0 MPa working pressure, 1.5 MPa proof, -20 to +70 C, and vacuum to -750 mmHg. The thread arrives pre-coated with sealant, so no extra tape is needed on the PT side.

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 PMF801 Is Used
Control cabinet pass-through
Bolt the PMF801 through the wall of an electrical enclosure on a packaging machine so the 1/8in PT port lives inside with the valve manifold while the Dia 8 tube run stays routed outside the cabinet.
Analyser instrument panel
On a laboratory gas analyser or sample-conditioning panel, a bulkhead connector gives a fixed, labelled tube entry point through the sheet-metal housing, with the PT thread inside available for a filter or regulator take-off.
Machine enclosure air entry
Feed Dia 8 tubing through the side wall of a CNC coolant cabinet or wash-frame guard, keeping the push-in fitting accessible on the outside for fast tube changes during changeover.
Is the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF801 the Right Part?
This is the Dia 8, 1/8in position in the PMF ladder. Step down to PMF601 for Dia 6 tube - the locknut shrinks from M16x1 to M14x1, so the panel hole gets smaller too. Step up to PMF1002 for Dia 10 tube, which grows the locknut to M20x1 and gives a wider flow path through the bore. If you do not need a threaded port on the far side and just want tube through tube, the PM bulkhead union is the simpler choice.
Match the 1/8in PT thread to the port or adapter you are feeding, and check the panel hole suits an M16x1 locknut before ordering. Tube OD must match exactly: a Dia 8 chuck will not seal on 5/16in or 10 mm tube.
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 PMF801 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, temperature range -20 to +70 C. It accepts Dia 8 mm soft nylon or polyurethane tube on the one-touch side and has a 1/8in PT thread with an M16x1 bulkhead locknut. Grey body as standard (D suffix = black), POM chuck and release button, NBR seal, threaded parts supplied with sealant applied.
The Dia 8 PMF uses an M16x1 locknut, so the panel cut-out must suit that nut thread - typically around 16 mm clearance depending on your nut. Do not swap a PMF801 into a panel drilled for the Dia 6 version, which takes an M14x1 locknut, or the Dia 10 version at M20x1. Hand-tighten the nut square to the panel so the O-ring seats evenly; AirTAC does not publish a torque figure.
