The AirTAC Airtac POC Round Thread Straight Connector POC602 is a genuine male connector (compact) for push-in tube connection, rated 0 - 1.0 MPa (0 - 10 kgf/cm2) with a 1.5 MPa proof pressure.
The POC602 is an AirTAC POC male connector, the compact-bodied version of the standard one-touch straight fitting. It pushes onto Dia 6 mm soft nylon or polyurethane tube on one side and screws into a 1/4in PT male port on the other. Push the tube home and the stainless spring gasket plus POM chuck grip it under any pressure including vacuum down to -750 mmHg; press the release button to free it again.
This is the resin/brass one-touch line: 0-1.0 MPa working pressure, 1.5 MPa proof pressure, and -20 to +70 C service. The body on POC threaded parts is PBT with a brass stud, the release button and chuck are POM, and the 1/4in thread arrives with sealant already applied so no tape is needed on the taper.

The short POC body clears the narrow gap between a small pneumatic gripper and its surrounding bracket on a pick-and-place head, where a standard-length PC connector would foul the arm at top of stroke.
Many compact valve islands and single solenoids carry 1/4in PT outlet ports; POC602 threads straight on and routes 6 mm hose to downstream cylinders without an adapter.
Rated to -750 mmHg (10 Torr) negative pressure, the sealed one-touch joint holds vacuum feed lines on tray-sealing and vacuum-forming machines where a loose push-in joint would bleed the cycle down.
Within the 1/4in thread, the neighbouring tube sizes are Dia 4 (POC402) and Dia 8 (POC802): step down for light pilot lines and small actuators, step up when flow demand or line length grows. For thread steps on a Dia 6 tube, go to 1/8in (POC601); note there is no POC603, because the 3/8in POC ladder only starts at Dia 8, so 1/4in is the largest factory thread for this tube size.
Tube OD must match exactly. A Dia 6 mm fitting will not seal 1/4in (6.35 mm) imperial tube even though the numbers look close. If your port is a panel-mounted female hole rather than a male stud, the PCF female connector is the shape to compare.
Quick checklist
Working pressure 0-1.0 MPa (0-10 kgf/cm2); negative pressure -750 mmHg (10 Torr); proof pressure 1.5 MPa; temperature -20 to +70 C. The fitting accepts Dia 6 mm soft nylon or polyurethane tube and has a 1/4in PT male thread supplied with pre-applied sealant. It belongs to AirTAC's resin/brass one-touch range, not the 0.9 MPa metal line.
No. The chuck grips the tube's outside diameter, so a Dia 6 mm fitting only holds 6.00 mm tube. 1/4in tube measures about 6.35 mm and will either not enter or leak under pressure. Match the tube OD exactly, or specify a fitting made for the imperial size instead.
