Copper Shell-And-Tube Heat Exchanger Tube Bundle / Core Insert - Used

Copper shell-and-tube heat exchanger tube bundle / core insert, the style used in raw-water-cooled marine diesel and marine generator cooling systems (also used as an oil-cooler bundle in similar designs). Application: not verified — no data plate, tag, or part number is present on this unit, so it is sold by photographs, identifiers, and dimensions. Approximately 30 in long with a shell OD of roughly 4-1/4 in.

Condition: used and untested. The copper body shows heat discoloration and patina, and the internal tubes visible through the access windows show green verdigris from prior service. No pressure test, flow test, or cleaning has been performed and none is implied. Treat this as an untested core that should be cleaned and pressure tested by a qualified heat-exchanger shop before installation. It will be drained and the ports capped before shipping.

Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
