Multiquip RE55498 DEF Supply Filter Kit - OEM Replacement Part for Super Silent Generators

This DEF (Diesel Exhaust Fluid) supply filter kit maintains the integrity of your emissions system by filtering contaminants from the DEF supply line before they reach critical SCR (Selective Catalytic Reduction) components. Regular replacement of DEF supply filters prevents crystallization buildup, system faults, and costly downtime on Tier 4 Final compliant generators.

The kit includes replacement filter cartridges and gaskets required for complete service. During installation, coat each new gasket with a small amount of clean 15W-40 engine oil as specified in Multiquip maintenance procedures. Install filter cartridges by hand until they make contact with the filter body surface, then tighten securely without overtightening to prevent damage to gasket seals or housing threads.

Compatible with the following Multiquip Super Silent Generator models:

• DCA180SSJU4F3
• DCA180SSJU4F

Regular DEF filter maintenance is essential for maintaining emissions compliance and preventing ECU fault codes. Contaminated DEF supply can lead to system derates, reduced performance, and extended regeneration cycles.
