About the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF802
The PMF802 is an AirTAC PMF bulkhead connector, a one-touch push-in fitting made to pass a Dia 8 mm pneumatic line through a panel, cabinet wall or machine plate. The brass stud goes through the hole and is secured with an M16x1 locknut, leaving a 1/4in PT female thread on one side for the component port and a push-in chuck on the other for the tube. Push the tube home and the internal chuck grips it under pressure; press the release ring and it slides free.
This part belongs to AirTAC's resin and brass one-touch line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a service range of -20 to +70 C. The body is PBT over a brass stud, the release button and chuck are POM, and the seal is an NBR O-ring on a stainless spring gasket. The thread arrives with sealant pre-applied, so it seals on PT ports 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 PMF802 Is Used
Control cabinet pass-through
On a packaging machine's electrical enclosure, the PMF802 studs through the cabinet wall with its M16x1 locknut, so the 1/4in PT side serves a valve manifold inside while the Dia 8 tube runs to the outside pneumatics without a single fitting inside the panel.
Machine base plate feed on a chip conveyor
Feeding a Dia 8 mm line to the lift cylinder of a CNC chip conveyor, the fitting is locked into a drilled hole in the base plate, keeping the pneumatic connection accessible from the front instead of buried under guarding.
Bench-mounted test rig plumbing
On a leak-test bench, the bulkhead stud turns a plywood or aluminium dividing plate into a serviceable air interface - one PMF802 per circuit lets technicians disconnect Dia 8 tubing by hand during fixture changeovers.
Is the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF802 the Right Part?
Within the PMF ladder this SKU sits at Dia 8 tube on a 1/4in thread. Step down to Dia 6 on the same 1/4in thread when the line feeds a smaller actuator, or step up to Dia 10 where the run carries more volume - the bore change alters flow capacity through the fitting, so match it to the tubing, not the port alone. On the thread side, 1/8in and 3/8in variants of the PMF series also exist if the receiving port calls for them.
Choose a bulkhead shape whenever the tube must cross a fixed barrier and you do not want to thread a fitted line through a cramped cutout: the fitting stays clamped to the panel and both sides can be assembled in the open. Remember that tube OD must match exactly - this chuck holds Dia 8 mm tubing only and 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 PMF802 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature range of -20 to +70 C. It accepts Dia 8 mm soft nylon or polyurethane tube on the push-in side and presents a 1/4in PT female thread on the other, with an M16x1 bulkhead locknut thread. The thread comes with sealant pre-applied.
Yes. The same chuck and NBR seal that hold the Dia 8 tube at 1.0 MPa are rated down to -750 mmHg (10 Torr), so the fitting handles vacuum pick-up and evacuation lines. Keep the tube flexible and fully bottomed in the chuck, because a partly inserted tube is the usual cause of a vacuum-side leak at a push-in fitting.
