Cummins OEM Part Number: 4025270

This is a Cummins engine component, packaged by Cummins Atlantic and sealed inside ARMOR WRAP VCI corrosion‑inhibitor packaging. The visible metal ring with a white inner liner and the small included hardware strongly indicate:

⭐ Cummins 4025270 – Turbocharger Bearing Housing Seal / Journal Bearing Kit

This part is used inside the center housing rotating assembly (CHRA) of a Cummins turbocharger. The white inner liner is the bearing surface, and the metal outer ring is the retainer/seal assembly. The small dark components are the retaining clips / thrust pieces used during turbo rebuild.

This is NOT a gasket, not a fuel part, not a sensor — it is turbocharger internal hardware.
