Can flush bushings be used?

In fire-extinguisher systems, every part that interfaces with the pressure and the discharged agent must be an approved, rated component. Flush bushings aren’t designed, tested, or approved for use in these systems, so they can fail to seal or seat properly, leak under pressure, or misalign the discharge path. This can compromise the extinguisher’s reliability and safety, and it would violate manufacturer specifications and applicable codes. Because of these safety concerns, they should not be used at all; if a different configuration is needed, an approved part or an explicit authorization from the manufacturer or authority is required.
