Mitsubishi OEM Copper Crush Washer 14mm — Evo 5/6/7/8/9 — Part #MF660065

Firstly, Buy Mitsubishi OEM Copper Crush Washer 14mm MF660065 for Evo 5/6/7/8/9. The Mitsubishi OEM Copper Crush Washer 14mm Evo 5/6/7/8/9 MF660065 is a genuine Mitsubishi replacement sealing washer designed for use with various fluid connections on Mitsubishi performance vehicles. Manufactured from copper, this 14 mm crush washer is designed to deform slightly when tightened, helping create a reliable seal between mating surfaces and reducing the chance of fluid leakage.

Part number MF660065 is commonly used on Mitsubishi Lancer Evolution turbocharger water lines and other factory fluid connections. Mitsubishi specialists list this washer for Evolution applications and identify it as a genuine OEM 14 mm copper crush washer.

For owners maintaining an Evo 5, Evo 6, Evo 7, Evo 8, or Evo 9, replacing the original crush washer during turbocharger, coolant-line, or engine work is an inexpensive but important part of proper assembly. A crush washer that has already been compressed may not seal as effectively when reused, which is why a new washer is recommended whenever the related connection is serviced.

Mitsubishi OEM Copper Crush Washer 14mm MF660065

The Mitsubishi OEM Copper Crush Washer 14mm MF660065 is designed as a factory-style sealing component rather than a generic universal washer. Its copper construction allows the washer to conform to the mating surfaces as the fastener is tightened, helping establish a secure seal around the connection.

This type of washer is particularly important around turbocharger coolant lines because these connections are exposed to engine heat, coolant pressure, and repeated temperature cycles. A properly sealed connection helps prevent coolant from escaping around banjo-style or similar fluid fittings.

The MF660065 is also identified in Mitsubishi parts listings as a copper gasket or 14 mm crush washer. Mitsubishi OEM gasket kits include MF660065 among their specified sealing components, further confirming its use as a factory fluid-line sealing washer.

Genuine Mitsubishi OEM Construction

Firstly, MF660065 is a genuine Mitsubishi OEM part number. Using an OEM sealing washer helps maintain the correct factory-style configuration when servicing your Evolution’s engine, turbocharger, or fluid lines.

Instead of trying to reuse an old compressed washer, installing a new OEM copper crush washer provides a fresh sealing surface during reassembly.

14mm Copper Crush Washer Design

Secondly, the 14 mm copper construction is designed specifically for the applicable Mitsubishi fluid-line connections. Copper is well suited to crush-washer applications because it can deform under the correct tightening load and conform to minor surface irregularities.

The result is a simple, compact seal that works with the corresponding Mitsubishi fitting or bolt.

Ideal for Turbocharger and Cooling-System Service

Thirdly, MF660065 is commonly used with turbocharger water lines on Mitsubishi Evolution and DSM applications. STM specifically describes it as the crush washer for many turbo water lines and also lists applications involving the Evo 9 MIVEC head and Evo X ACD transfer-case feed line.

For an Evo 5/6/7/8/9 owner, this makes MF660065 a useful replacement item to keep on hand when removing turbo coolant lines, servicing fittings, or rebuilding components.

Applications for Mitsubishi Evo 5/6/7/8/9

The MF660065 part number is widely cataloged across Mitsubishi Evolution applications.

Other listings extend the application through the Evolution I–X range, although exact usage can vary by connection and vehicle configuration.

For this reason, it is best to match the part number against the specific fluid connection or factory parts diagram when ordering multiple washers for a complete rebuild.

Why Replace a Copper Crush Washer?

Copper crush washers are designed to seal through controlled deformation. Once installed and compressed, the washer may not return to its original shape. Reusing it can therefore increase the possibility of seepage or an imperfect seal.

Replacing the washer is especially worthwhile when:

• Removing a turbocharger water line
• Servicing the turbocharger
• Replacing coolant hoses or water pipes
• Rebuilding a 4G63 engine
• Reinstalling banjo-style fluid fittings
• Performing a cooling-system refresh
• Restoring an Evo to factory specifications
• Repairing a coolant or fluid leak
• Reassembling components after powder coating or engine-bay restoration

A new washer is inexpensive compared with the time required to diagnose and repair a leak after the vehicle has been reassembled.

OEM Replacement for Mitsubishi Evolution Builds

For enthusiasts working on an older Evolution, small OEM sealing components can be just as important as larger engine and turbocharger parts. The MF660065 helps maintain the correct factory sealing arrangement without relying on an aftermarket substitute of uncertain dimensions or material.

Whether you are rebuilding an Evo 5 or Evo 6 4G63, refreshing an Evo 7 or Evo 8 turbo system, or servicing an Evo 9 MIVEC engine, keeping the appropriate OEM crush washers available can make the installation process cleaner and more reliable.

The washer is also useful as part of a larger maintenance order because multiple fluid connections may be opened during turbocharger and engine work.
