About the Airtac PC Threaded Straight Connector PC3.2M5D-M
The PC3.2M5D-M is AirTAC's mini-series PC male connector, the smallest one-touch fitting in the catalogue. Its brass body screws into an M5x0.8 female port and its chuck accepts Dia 3.2 mm soft nylon or polyurethane tube. Push the tube home and the stainless spring gasket plus POM chuck lock it against the brass body; press the release ring and the tube slides straight out again. The D suffix on a PC part changes only the release button to black - the body remains the standard grey.
This is the resin/brass spec profile, not the metal line: working pressure 0-1.0 MPa, vacuum down to -750 mmHg, proof pressure 1.5 MPa and a temperature window of -20 to +70 C. Because the thread is M5x0.8, sealing comes from a gasket at the shoulder rather than pre-applied thread sealant, so a small wrench flat is all it takes to make the joint. The -M mini series is offered by AirTAC on the PC and PL prefixes only, which is why a 3.2 mm connector exists here and nowhere else in the range.

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 PC3.2M5D-M Is Used
Miniature cylinder pilot lines
Feeding a Dia 3.2 mm pilot or sensing line to a compact pneumatic cylinder on a pick-and-place head, where an M5x0.8 port is the only tapping the casting allows.
Analytical and lab instruments
Routing low-volume air or purge flow between small valve manifolds and sample chambers in laboratory equipment, where the M5 gasket seat keeps a tidy leak-free joint.
Small jigs and fixtures
Connecting a palm-sized air cylinder on a clamping jig orfixture where panel space rules out full-size Dia 4 or 6 mm fittings entirely.
Is the Airtac PC Threaded Straight Connector PC3.2M5D-M the Right Part?
Dia 3.2 mm is the bottom of the ladder - there is no smaller tube size in this catalogue, so this is the fitting you land on when nothing bigger will do. The next step up is Dia 4, ordered as PC4M5-M in the same mini series, and the step up from M5 is M3, which AirTAC also offers on the mini series for the tiniest ports. If your port is a conventional 1/8" PT tapping, you have left the mini series: use a standard PC401 instead. Whatever you choose, tube OD must match exactly - a Dia 3.2 mm chuck will not grip 4 mm tube and will leak or blow off under pressure.
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 PC3.2M5D-M FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. The fitting joins Dia 3.2 mm soft nylon or polyurethane tube to an M5x0.8 male thread (PT standard family, M5 sealed by gasket). It is the mini PC series with a black release button and grey body.
No. One-touch chucks grip one exact outer diameter, so a Dia 3.2 mm fitting will not seal on 4 mm tube. Order PC4M5-M for Dia 4 mm tubing, or if you need the smallest possible port thread rather than the smallest tube, the mini series also offers an M3 thread variant.
