ISO 6149
For ISO 6149, region of origin is ISO Connections; thread type (tapered or parallel) is straight threads; seat or flare angle is flat face; seal method is The male connector has straight threads with an O-ring. The female port is also straight threads machined surface to provide a smooth, flat, accurately located surface (minimum spotface), along with a chamfer where the O-ring seats. It seals when the O-ring is compressed into the chamfer when mating the male connection; interchangeability notes is similar to the SAE J514 Straight Thread O-ring Boss (ORB), this type of connection incorporates metric threads, recorded from its source on 2026-08-13.

What the source says
ISO 6149 Port and Stud Ends with ISO 261 Threads and O-ring Seal though it is similar to the SAE J514 Straight Thread O-ring Boss (ORB), this type of connection incorporates metric threads. The male connector has straight threads with an O-ring. The female port is also straight threads machined surface to provide a smooth, flat, accurately located surface (minimum spotface), along with a chamfer where the O-ring seats. It seals when the O-ring is compressed into the chamfer when mating the male connection. This is also considered a mechanical connection.
