US fluid systems manufacturer Swagelok has disposed of its sole Gulfstream G550, according to ch-aviation research. The company removed it from the US aircraft register before exporting it to San Marino, where it is now being operated by business jet management and charter operator TAG Aviation San Marino (TAG, Rimini).

Federal Aviation Administration records show that N598K (msn 5235) had its US registration cancelled on July 31, 2024. It was entered into the Sammarinese registered as T7-G550 the following day. The fifteen-year-old aircraft was delivered straight from the Gulfstream factory to Swagelok in 2009. According to ch-aviation fleets data, Swagelok retains a single G280 business jet.

T7-G550 joins a 12-strong fleet at TAG Aviation's San Marino base, including one ACJ318-100, one Falcon 900LX, one G280, one G450, one G550, one G650, one G650ER, one GVII-G600, two Bombardier Global 5000s, one Global 6000, and one Global 7000.
