About the Airtac PC Threaded Straight Connector PC3.2M3D-M
The PC3.2M3D-M is AirTAC's PC male connector built in the -M mini format, pairing the smallest tube bore in the catalogue, Dia 3.2 mm, with an M3 male thread. Push the tube into the chuck and the stainless spring gasket grips it instantly for a sealed line; press the release ring and the tube frees again for rework. This D-code version carries a black release button, while the PC body itself stays grey.
It runs on the resin and brass one-touch profile: 0-1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C, with a POM button and chuck, an aluminium-alloy guide, a stainless spring gasket and an NBR O-ring on a brass body. Do not confuse this mini part with the metal BPC line, which trades 0.1 MPa of working pressure for a 150 C temperature limit that resin fittings cannot reach.

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 PC Threaded Straight Connector PC3.2M3D-M Is Used
Laboratory autosampler plumbing
Feeds 3.2 mm nylon line to the M3 ports on small solenoid valves inside a benchtop analytical autosampler, where full-size fittings simply will not clear the valve manifold pitch.
Micro pick-and-place head
Supplies vacuum to a compact ejector on a miniature gantry, using the 3.2 mm bore to keep hose routing light and flexible around the Z-axis.
3D printer air assist
Delivers a slim air-assist stream to a compact print head, with the M3 stud threading directly into printer-board accessory ports and the black button staying visible against dark hardware.
Is the Airtac PC Threaded Straight Connector PC3.2M3D-M the Right Part?
Dia 3.2 mm is the floor of the range and exists only on the PC and PL mini series, so there is no smaller step. The next size up is Dia 4 in the same mini ladder: the bore grows enough to feed slightly hungrier micro-actuators, but the tube must change with it, because a 3.2 mm chuck will not hold 4 mm tubing and a Dia 4 fitting will not seal 3.2 mm tube. On the thread side, M3 is the smallest option, with M5 as the next step up in the mini series; anything larger moves you out of the mini format into the standard PC range starting at 1/8".
Match the M3 stud to the small tapped ports found on miniature valves, ejectors and sensor blocks, and hand-start it carefully: fine-pitch mini threads gall far more easily than 1/8" ports if cross-threaded.
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 PC Threaded Straight Connector PC3.2M3D-M FAQ
Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure goes to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. The fitting joins Dia 3.2 mm soft nylon or polyurethane tube to an M3 male thread in AirTAC's mini (-M) format, with the D suffix denoting a black release button.
No. The chuck and spring gasket are sized for exactly 3.2 mm outside diameter, so 4 mm tube will not insert and 3.2 mm tube will leak in a Dia 4 fitting. Use soft nylon or polyurethane of the matching 3.2 mm OD, and if your run already uses 4 mm tube, step up to the Dia 4 mini connector instead of forcing a mismatch.
