About the Airtac PC Threaded Straight Connector PC3.2M5-M
The PC3.2M5-M is AirTAC's mini series PC male connector, a one-touch push-in fitting that joins Dia 3.2 mm soft nylon or polyurethane tubing to an M5x0.8 male thread. The -M suffix marks it as a miniature body: the whole fitting is scaled down so it can sit where a full-size connector would foul neighbouring components, and the 3.2 mm tube size exists only in this mini line. To make the joint, push the tube firmly into the chuck until it bottoms out - the internal grip rings hold it against pressure, and pressing the POM release ring lets the tube pull free for rework.
This part belongs to the resin and brass one-touch profile, so it is rated 0-1.0 MPa (0-10 kgf/cm2) working pressure, handles vacuum down to -750 mmHg (10 Torr), carries a 1.5 MPa proof pressure and works from -20 to +70 C. The body is brass with a POM release button and chuck, an aluminium-alloy guide, a stainless spring gasket and an NBR O-ring. Because this is an M5 size, the thread seals with a supplied sealing gasket rather than the pre-applied sealant AirTAC puts on the larger tapered threads. The standard finish is grey; on the PC family a D suffix changes only the release button, not the body.

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 PC3.2M5-M Is Used
Miniature cylinder on an electronics assembly jig
Small-bore guiding and clamping cylinders on PCB handling jigs are usually ported M5x0.8, and their air lines run 3.2 mm because anything larger overpowers the tiny actuation volumes. This connector screws straight into the cylinder port and takes the tube with one push.
Vacuum pick-and-place head for light loads
A compact suction cup holder or mini ejector on a desktop pick-and-place gantry draws only a little air, so a 3.2 mm line loses almost nothing while keeping the head featherweight. The fitting is rated down to -750 mmHg, so full vacuum on the cup is no problem.
Instrument air take-off inside a compact gripper
Two-finger electric-pneumatic hybrid grippers and small robot end-effectors often need a low-volume purge or sensing line. The mini body fits between the gripper fingers where a standard PC connector would collide with the workpiece.
Is the Airtac PC Threaded Straight Connector PC3.2M5-M the Right Part?
Dia 3.2 mm is the smallest tube size in the entire one-touch catalogue - there is nothing below it, so this is the floor of the range. The next step up is Dia 4 mm, which AirTAC offers in the same mini M5 format as well as the standard PC row (M5 supports Dia 4 and Dia 6 there); stepping up gains you a stiffer bore and a bigger effective flow area for the same M5 port, at the cost of a slightly larger fitting envelope.
Before ordering, check two things. First, your tube must be genuinely Dia 3.2 mm OD - pushing 4 mm or 1/4" tube into this chuck will not seal, and there is no adapter inside the fitting. Second, confirm your receiving port really is M5x0.8: this miniature thread is common on small cylinders, manifolds and valve bodies, but if the machine port is 1/8" PT you need the full-size PC series instead, which is not merely a scaled version of this part.
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 PC3.2M5-M FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C. It connects Dia 3.2 mm soft nylon or polyurethane tube to an M5x0.8 male thread (PT standard), and this M5 size seals with a supplied gasket instead of thread sealant.
No. The chuck inside is sized for Dia 3.2 mm outside diameter only - a 4 mm or 6 mm tube will neither seat nor seal, and forcing it damages the grip rings. If your run is 4 mm tube, order the Dia 4 mini or standard PC connector in the same M5 thread instead. Likewise, if your port is 1/8" rather than M5x0.8, move to the full-size PC series; the mini body and that thread are not interchangeable.
