About the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF601D
The PMF601D is an AirTAC PMF bulkhead female connector, the push-to-connect fitting designed to carry a Dia 6 mm tube through a machine wall or cabinet panel. One end of the brass stud holds the one-touch chuck for 6 mm soft nylon or polyurethane tubing; the other end presents a 1/8in PT female thread to your male port hardware. Push the tube home and the stainless spring gasket with the POM chuck grips it instantly; press the release ring and the tube frees again without tools.
This belongs to the resin and brass one-touch line, not the metal BP family: working pressure 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum capability to -750 mmHg, proof pressure 1.5 MPa, and service from -20 to +70 C. The body is PBT with a brass stud and an NBR seal, and because the code ends in D the whole body ships in black rather than standard grey - on PMF the D suffix colours the body itself, not just the button as it does on PC. Threaded portions arrive with sealant already applied, and the Dia 6 stud is clamped by an M14x1 bulkhead locknut.

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 PMF601D Is Used
Guard-wall feed on a blister packaging machine
Pass the PMF601D through the rear sheet of a blister pack machine guard so the 6 mm cylinder feed can be connected and released outside the guarded zone, with the 1/8in female port taking the valve drop on the service side.
Backplate distribution in a palletiser cabinet
Mount the fitting through the electrical backplate of a palletising cell and pick up air with a male-threaded distribution stud, keeping all 6 mm tube runs inside the cabinet and away forklift traffic.
Vacuum pick-up on a benchtop handling fixture
The -750 mmHg (10 Torr) vacuum rating lets this fitting serve a lab benchtop pick-and-place fixture, passing 6 mm vacuum tube through a small mounting plate down to the ejector or venturi below.
Is the Airtac PMF Female Thread Bulkhead Straight Through Fitting PMF601D the Right Part?
Down one tube size sits the PMF401, Dia 4, which uses the smaller M12x1 locknut and suits light pilot lines; up is the PMF801, Dia 8 with an M16x1 locknut, for feeds to larger cylinders. In thread there is no M5 option anywhere in the PMF range, so 1/8in is the entry point - step up to PMF602 when the port is a 1/4in. The female panel-side thread lets you keep your existing sealing arrangement on the mating male stud instead of adding a separate adaptor.
Match the tube exactly: the chuck is machined for 6 mm OD and will not hold 1/4in hose, which measures 6.35 mm and would leak under pressure. If the fitting does not actually need to pass through a wall, a PC straight connector or PL male elbow is the simpler and cheaper shape.
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 PMF601D FAQ
Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), vacuum capability is -750 mmHg (10 Torr), and proof pressure is 1.5 MPa. Service temperature is -20 to +70 C. This SKU grips Dia 6 mm soft nylon or polyurethane tube on the one-touch side and offers a 1/8in PT female thread on the panel side, clamped by an M14x1 bulkhead locknut.
Drill a clearance hole for the brass stud, pass the fitting through, and clamp it with the M14x1 locknut - AirTAC publishes no tightening torque, so snug the nut and confirm the tube is not being pulled sideways rather than over-tightening. No, the chuck grips only 6 mm OD tube; 1/4in hose measures 6.35 mm and will not seal in this fitting.
