About the Airtac PC Threaded Straight Connector PC4M5D-M
The PC4M5D-M is the miniature version of AirTAC's PC male connector, a one-touch fitting that joins Dia 4 mm soft nylon or polyurethane tubing straight into an M5x0.8 port. Push the tube in until it bottoms and the stainless spring gasket and chuck clamp it; press the black release ring to free it again. The M suffix marks the mini series, so the body footprint is smaller than the standard PC4M5, which matters on dense valve manifolds and instrument blocks.
It uses the resin and brass one-touch profile: 0 to 1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure and -20 to +70 C. On PC fittings the D suffix changes the release button to black only, so the body finish stays the standard grey, and M5 threads seal with a supplied gasket instead of the pre-applied sealant used on larger sizes.

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 PC4M5D-M Is Used
Pick-and-place ejector heads
Mini vacuum ejectors and small gripper cylinders on pick-and-place heads commonly carry M5 ports; the Dia 4 line keeps hoses light so the moving head is not dragged by its own air supply.
Benchtop lab instrumentation
Analytical and test instruments with M5 pneumatic ports take this connector directly, and the push-fit joint lets a technician swap tubing during servicing without unwrapping thread sealant.
Compact assembly fixtures
Where a fixture plate packs several Dia 4 lines onto miniature cylinders, the mini body shortens the fitting so adjacent M5 ports stay accessible with a small spanner.
Is the Airtac PC Threaded Straight Connector PC4M5D-M the Right Part?
Dia 4 with M5 sits at the small end of the PC ladder. Below it, only the 3.2 mm tube size exists and only inside the PC and PL mini series; one step up on the same M5 port is PC6M5 for Dia 6 tubing, which gives a stiffer line and more effective bore. If the port is actually 1/8 instead of M5, PC401 carries the same Dia 4 tube on the bigger thread, so check the port marking before ordering - M5x0.8 is a metric fine thread and will not mate with a 1/8 PT port.
The PC male connector screws directly into a threaded port, so it is the right shape when the fitting terminates at a component rather than continuing as a union. Remember that one-touch grips on exact tube OD only: a Dia 4 chuck will not hold 5/32 or 3 mm tubing even where it seems close.
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 PC4M5D-M FAQ
It is a mini one-touch male connector for Dia 4 mm tubing with an M5x0.8 male thread (PT thread standard across the catalogue). Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 1.5 MPa, and the working temperature range is -20 to +70 C with soft nylon or polyurethane tubing.
No tape is needed. M5 sizes in this range arrive with a sealing gasket for the thread rather than the pre-applied sealant fitted to the 1/8 and larger threads, so seat the gasket, start the fitting by hand into the port and snug it down gently. Over-tightening a small M5 thread into an aluminium manifold is the usual way these get damaged, not under-tightening.
