About the Airtac PC Threaded Straight Connector PC6M5-M
The PC6M5-M is a mini-series PC male connector, the straight push-in fitting AirTAC builds for small ports. One end grips a Dia 6 mm soft nylon or polyurethane tube; the other is an M5x0.8 male stud, the fine-pitch thread stamped on compact valve and cylinder ports. Push the tube home and the internal chuck grips it under the spring gasket; press the POM release button and the ring frees the tube again. The -M suffix marks the mini series: same gripping principle as the standard PC, scaled down so the body and wrench flats clear neighbouring ports on dense manifold faces.
This fitting uses the resin and brass spec profile, not the metal BPC line: working pressure 0-1.0 MPa (0-10 kgf/cm2), vacuum to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a -20 to +70 C temperature window. Materials are a brass body, POM release button and chuck, aluminium-alloy guide, stainless spring gasket and NBR O-ring. One detail worth knowing before you wrench it down: M5 sizes do not arrive with pre-applied thread sealant like the larger PT threads. The M5 stud seals through a dedicated sealing gasket faced against a flat seat, so no PTFE tape is needed or wanted here.

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 PC6M5-M Is Used
Compact solenoid valve manifolds
Mini directional valves on pick-and-place heads often carry M5x0.8 ports spaced a few millimetres apart. The PC6M5-M's reduced mini body and wrench flats let you land a Dia 6 line on one port without fouling the fitting next door.
Small pneumatic grippers on robots
Two-finger mini grippers and rotary actuators on SCARA or cobot end effectors commonly specify M5 supply ports. A straight Dia 6 connector keeps the airline routing clean on a wrist that is already crowded with cabling.
Benchtop lab and dosing fixtures
Small-bore air circuits on dispensing and test benches - sample actuation, low-flow air jets - run comfortably in Dia 6 tube. The M5 stud screws directly into the ported aluminium fixture plate, gasket sealing against the machined face.
Is the Airtac PC Threaded Straight Connector PC6M5-M the Right Part?
On the M5 thread, the PC ladder only offers Dia 4 and Dia 6. The size below is the PC4M5-M, which drops the bore to 4 mm for genuinely tiny actuators; there is no Dia 8 option on M5 at all. If your circuit grows beyond Dia 6, the step up is a thread change, not a tube change: the standard-series PC601 keeps the 6 mm bore but moves to a 1/8 in PT stud. Match the port you actually have - M5x0.8 is fine pitch and will not interchange with an M6 or a 1/8 in port.
Two fit checks before ordering. First, the gasket face needs a clean, flat machined seat around the port; a rough tapped hole will not seal on the gasket. Second, tube OD must match exactly: this fitting holds 6 mm tube only, and 1/4 in (6.35 mm) imperial tube is loose enough in a Dia 6 chuck to leak or blow out 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 PC6M5-M FAQ
Tube size: Dia 6 mm soft nylon or polyurethane. Thread: M5x0.8 male, sealed by a sealing gasket (no thread sealant). Working pressure: 0-1.0 MPa (0-10 kgf/cm2). Negative pressure: -750 mmHg (10 Torr). Proof pressure: 1.5 MPa. Temperature range: -20 to +70 C. Construction: brass body, POM release button and chuck, aluminium-alloy guide, stainless spring gasket, NBR O-ring. Grey body as coded; on the PC series a D suffix changes only the release button colour.
No. Unlike the larger 1/8 to 1/2 in PT threads in this catalogue, which arrive with pre-applied sealant on the stud, the M5x08 stud on the PC6M5-M seals through a dedicated sealing gasket. Thread the fitting in until the gasket meets a flat, clean machined face around the port and tighten gently - the gasket does the sealing, so the mating surface matters more than torque.
