MTU Cast Iron Two-Bolt Port Flange / Spacer Collar - Used (Lot of 6)

Lot of 6 MTU cast-iron two-bolt port flange / spacer collars, pulled from service. Each piece carries the mtu wordmark cast into the body along with casting number 506142 and additional foundry marks — these are casting numbers, not confirmed OEM service part numbers.

Application: MTU diesel engine accessory flange — most consistent with an exhaust or fluid-transfer port connection. Engine series and exact application are NOT verified; the parts are offered by photographs, cast identifiers, and dimensions only. Buyers rebuilding or repairing MTU-powered vessels should verify against their parts manual before ordering.

Condition: Used take-off, untested. Surface rust and scale throughout with remnants of old yellow paint. Gasket faces will need cleaning before reuse. No cracks visible, but no crack testing or pressure testing has been performed.

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.
