About the Airtac PC Threaded Straight Connector PC6M5D-S
The PC6M5D-S is AirTAC's PC male connector built as a straight push-in adaptor that joins Dia 6 mm soft nylon or polyurethane tubing to a port tapped M5x0.8. Push the tube home and the internal chuck grips it under the spring gasket; press the POM release ring and the tube slides straight back out. The -S suffix makes this a member of AirTAC's stainless one-touch line: the connector body itself is SUS304, and AirTAC states the complete part is copper-free, so no copper alloy touches the air stream.
Because the -S version is a PC/POC-family stainless body, all of the standard resin-line ratings carry over unchanged: 0-1.0 MPa working pressure, -750 mmHg (10 Torr) vacuum, 1.5 MPa proof pressure and -20 to +70 C. Do not re-rate it for the higher figures - those belong to the separate BP metal line. One detail unique to the small thread: M5 ports seal with a captive sealing gasket rather than pre-applied thread sealant, so the fitting seats cleanly into compact valve and sensor ports without paste migrating into the pilot circuit. The D suffix on a PC part changes only the release button to black; the SUS304 body stays as-is either way.

POM release button and chuck, aluminium-alloy guide, stainless spring gasket, NBR O-ring; body brass or PBT depending on the part. Stainless (-S): SUS304 in place of brass - a solid SUS304 body on the PC and POC straight connectors, and a PBT body with a SUS304 stud on the elbow, tee and branch shapes. Working pressure, proof pressure and temperature are unchanged from the standard version. AirTAC publishes flow as a characteristic curve rather than a single figure, so no L/min value is listed.

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 PC6M5D-S Is Used
Electroplating and surface-treatment shops
Pilot lines running valve actuators around plating tanks see acid mist and copper-salt carry-over. The copper-free SUS304 body of the PC6M5D-S avoids copper ions seeding unwanted reactions in rinse-water circuits, and the black release button stays findable on a grimy manifold.
Compact valve manifolds on bottling rinse decks
Small pilot-operated valves on bottle-rinse and tray-wash machines are commonly tapped M5x0.8 on the pilot face. This connector's gasketed M5 stud plus Dia 6 tube feed feeds those 2-3 mm pilot ports with no sealant to wash into the spool area during caustic wash-down.
Semiconductor tool pneumatic sub-panels
Wafer-handling and metrology subsystems specify copper-free wetted parts to protect process chambers from copper contamination. A SUS304 PC body pushing Dia 6 nylon to an M5 sensor or pilot port meets that requirement without redesigning the panel layout.
Is the Airtac PC Threaded Straight Connector PC6M5D-S the Right Part?
The PC ladder in M5 covers exactly two tube sizes: Dia 4 and Dia 6. This Dia 6 version is the larger of the pair, so if your line is underserved on flow, PC6M5D-S is the ceiling for an M5 port - step to PC4M5D-S only when feeding a small Dia 4 actuator or sensor line. To carry Dia 8 or larger tube you must move to a 1/8" thread such as PC801D-S, because no Dia 8 M5 part exists in the PC table. Match the gasketed M5 stud to ports actually tapped M5x0.8; forcing it onto an M6 port strips both.
Tube OD must match the chuck exactly. A Dia 6 fitting will not grip 1/4 inch (6.35 mm) imperial tube even though the difference looks trivial on a ruler - the sealing face misses the gasket and the joint leaks or blows off. For inch tube you need the separate N-series inch catalogue, not 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 PC6M5D-S 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 6 mm soft nylon or polyurethane tube to an M5x0.8 male thread, and the stainless version carries the identical ratings and dimensions to the grey standard PC601-M5.
No. On the PC series the D suffix changes only the release button colour to black; the body, chuck, guide, spring gasket and NBR O-ring are identical to the grey version, and every pressure and temperature figure is unchanged. On some other AirTAC series D changes the whole body, but not here - so order on size and thread, not on button colour.
