Multiquip M5331401704 DEF Tank Band - OEM Replacement Part

The DEF tank band secures the Diesel Exhaust Fluid (DEF) tank in place on Multiquip WhisperWatt super silent generators, preventing movement and potential damage during operation and transport. This mounting band is critical for maintaining the integrity of the DEF system, which holds up to 29.8 gallons (112.9 liters) of diesel exhaust fluid required for Tier 4 Final emissions compliance on these units.

DEF systems on these generators work continuously during operation to reduce emissions through selective catalytic reduction (SCR). A secure tank mount ensures proper fluid delivery and prevents line damage or system failures that could trigger regeneration cycles or fault conditions. If the tank band shows signs of corrosion, cracking, or loosening, replacement is necessary to prevent tank displacement that could compromise fuel lines, DEF lines, or electrical components in the compact enclosure.

Compatible with the following Multiquip generator models:

• DCA300SSJU4F2
