About the Airtac PC Threaded Straight Connector PC4M5-M
The PC4M5-M is the mini-series version of the AirTAC PC male connector, sized for the smallest ports in the catalogue. It joins a Dia 4 mm soft nylon or polyurethane tube to an M5x0.8 male thread. Push the tube straight into the chuck and the stainless spring gasket grips it; press the POM release ring and it slides back out. The grey body pairs a brass stud with PBT threaded sections.
This is the resin one-touch profile: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature window of -20 to +70 C, so it keeps sealing in cold shop air that the metal BP line is not rated for. Because this is an M5 part, the thread seals with its supplied sealing gasket rather than the pre-applied sealant used on the larger PT threads.

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 PC4M5-M Is Used
Miniature pick-and-place head
Feed vacuum or actuation air to a small gripper on a compact robot arm, where the M5 port on the end-effector manifold leaves no room for a full-size connector body.
Lab fixture air lines
Run Dia 4 mm polyurethane tubing to test-rig clamps and probes with M5 ports, where the low -20 C rating and gasket-sealed thread keep the bench setup leak-free and easy to reconfigure.
Compact valve manifold drops
Take a Dia 4 mm branch off an M5 spare port on a small solenoid valve manifold inside a tight control cabinet, with the male stud threading straight in hand-tight plus a quarter turn.
Is the Airtac PC Threaded Straight Connector PC4M5-M the Right Part?
Dia 4 is the smallest tube this connector takes, and on the M5 row of the PC ladder it is the only size below Dia 6 - so there is no smaller option on M5. Step up to PC6M5-M if your line runs Dia 6 mm tube; the port thread stays M5 and only the bore and flow path grow. If your port is 1/8 instead of M5, the standard PC401 covers Dia 4 mm on that thread with a wider size ladder above it.
Match the thread to the port: M5x0.8 is the fine pitch used on small manifolds, compact valve sub-bases and miniature cylinder ports, and it seals on its gasket, not on tape or paste. Tube OD must match exactly - a Dia 4 mm fitting will not grip 3 mm or 5 mm tubing, and no adapter changes that.
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 PC4M5-M FAQ
It is a resin one-touch mini male connector for Dia 4 mm tube with an M5x0.8 thread. 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. Tubing is soft nylon or polyurethane and the M5 thread seals via its sealing gasket, not thread sealant.
Not with this SKU - the M5 stud is machined for that port. If your port is 1/8 PT, order PC401 instead, which takes the same Dia 4 mm tube on a 1/8 thread and opens the ladder up to Dia 6, 8, 10 and 12 for later. Conversely, if your manifold is M5 but your tube is Dia 6 mm, choose PC6M5-M. Never force a different tube OD into the chuck; it will not seal.
