About the Airtac PC Threaded Straight Connector PC3.2M3-M
The PC3.2M3-M is the smallest male connector AirTAC makes in the PC one-touch family, built on the -M mini platform. It joins Dia 3.2 mm soft nylon or polyurethane tubing to an M3 male thread, and it exists only because the mini series was created for it: neither the 3.2 mm tube size nor the M3 thread appears anywhere else in the catalogue. Push the tube home and the stainless spring gasket inside the chuck clamps it; press the POM release ring and it slides free again.
It runs on the resin and brass spec profile: 0 to 1.0 MPa working pressure, -750 mmHg vacuum capability, 1.5 MPa proof pressure and -20 to +70 C. The threaded stud is brass and arrives with sealant already applied, so it goes onto a small tapped port straight out of the bag. The body finishes in grey, with a POM release button and chuck, an aluminium-alloy guide and an NBR O-ring doing the sealing work.

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 PC3.2M3-M Is Used
Miniature pick-and-place heads
Feeds a compact vacuum or air-ejector circuit on a small robotic gripper head, where the M3 stud screws directly into a tapped port on the ejector body and the 3.2 mm tube routes cleanly through tight wrist geometry.
Laboratory and analytical instruments
Connects pilot air to a miniature valve or actuator inside a benchtop analyser, where the M3 thread and the -20 to +70 C resin profile match the low-flow, low-profile plumbing typical of instrument internals.
Compact jig and fixture tooling
Replaces a glued or barbed connection on a small clamping fixture, giving maintenance staff a push-in point they can release with one press instead of unwrapping tape and re-sealing a threaded joint every changeover.
Is the Airtac PC Threaded Straight Connector PC3.2M3-M the Right Part?
There is nothing below this SKU in the ladder - Dia 3.2 mm with M3 is the floor of the entire PC range. Step up once and you are on Dia 4 mm tube with an M5 thread (PC4M5-M), which gives you a slightly larger bore and the far more common M5 port, at the cost of a bigger envelope. If your port is already tapped M3, this is the only fitting in the catalogue that fits it without an adapter.
Tube OD must match exactly: a 3.2 mm fitting will not grip 4 mm tube and will not seal it either, so order tube sized specifically for the mini line rather than cutting down larger stock.
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 PC3.2M3-M FAQ
Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), it tolerates negative pressure down to -750 mmHg (10 Torr), proof pressure is 1.5 MPa, and the temperature range is -20 to +70 C. This SKU joins Dia 3.2 mm tubing to an M3 male thread and is a mini-series (-M) part; applicable tubing is soft nylon or polyurethane.
No. The chuck and spring gasket are sized for 3.2 mm OD tube only - that diameter exists in the AirTAC one-touch range solely on the PC and PL mini series, so order tube explicitly sold as 3.2 mm. If your run already uses 4 mm tube, the correct part is PC4M5-M, which pairs Dia 4 tubing with an M5 thread.
