The AirTAC Airtac POC Round Thread Straight Connector POC602D 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 POC602D is an AirTAC POC male connector (compact), the shorter-bodied sibling of the PC series. It joins Dia 6 mm soft nylon or polyurethane tube to a 1/4in PT male port, and the D suffix tells you the release button is moulded in black instead of the standard grey - on POC parts that is the only thing the D changes, so the body, dimensions and ratings are identical to the grey POC602.
Connection is one-touch: push the tube past the POM chuck and it locks; press the release ring to free it. This is the resin/brass spec profile, so it carries a 0-1.0 MPa working pressure, -750 mmHg vacuum capability, 1.5 MPa proof pressure and a -20 to +70 C window. The PBT threaded body arrives with sealant already applied to the 1/4in thread, and the internal NBR O-ring plus stainless spring gasket keep the grip even under vibration on the machine frame.

A Dia 6 nylon run from a vertical drop to the 1/4in port of a compact SMC-style gripper cylinder on an electronics assembly gantry, where the POC's short body clears the cylinder shoulder nut.
Screwed into the 1/4in outlet of a valve manifold on a cartoning machine, feeding Dia 6 polyurethane tube to a vacuum ejector block above the sealing station.
A Dia 6 soft nylon vacuum line picked up at the release ring on a liquid-handling station, where the -750 mmHg rating holds the draw for sample probe actuation.
POC in 1/4in thread is offered from Dia 4 up to Dia 12, so the POC602D sits second from the bottom of the ladder. Step down to POC402 for a Dia 4 tube feeding a small sensor or pilot line; step up to POC802 when a Dia 8 tube has to carry a cylinder or larger actuator - the bigger bore moves more air per stroke without changing the port size. Whatever you pick, the tube OD must match exactly: a Dia 6 chuck will not seal on 1/4in (6.35 mm) tube.
If the POC602D's compact straight body still fouls a shrouded port, a PLL extended male elbow or PH universal elbow in the same Dia 6 / 1/4in combination turns the run 90 degrees instead of forcing hose bends.
Quick checklist
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, and a temperature range of -20 to +70 C. The fitting joins Dia 6 mm soft nylon or polyurethane tube to a 1/4in PT male thread. It is the resin/brass profile - the 0.9 MPa / 150 C figures belong to the separate BPC metal family.
Only the release button, which comes in black rather than grey. On POC and PC straight connectors the D suffix does not change the body colour, the material, or any dimension, so the POC602D and POC602 are functionally interchangeable parts.
