Multiquip M3331402804 DEF Tank Band

The Multiquip M3331402804 is a genuine OEM DEF Tank Band designed for the DCA Super-Silent generator series, including DCA150SSJU4F, DCA180SSJU4F, DCA220SSJU4F, and DCA300SSJU4F models. As an authentic Multiquip OEM component, this band is manufactured to the exact specifications required for correct DEF tank retention on these ultra-silent diesel generators. Sourced directly through authorized Multiquip supply channels, the M3331402804 ensures a proper fit across the full range of compatible DCA Tier 4 Super-Silent models. If you are servicing a DCA series generator and need a dependable replacement, this is the correct part to order.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's exact material and dimensional specifications for secure, long-term DEF tank retention without risk of bracket fatigue or loosening under vibration.
• Direct-Fit Replacement — Designed to mount in the original bracket position on DCA Super-Silent generators, using the existing hardware points for a straightforward swap during service.
• Broad DCA Series Coverage — Compatible with DCA150SSJU4F, DCA180SSJU4F, DCA220SSJU4F, and DCA300SSJU4F Tier 4 Super-Silent generator models across multiple frequency variants.
• DEF System Integrity — A properly secured DEF tank prevents line stress, connector damage, and fluid leaks that can trigger emissions faults and interrupt generator operation.
• Emissions System Compliance — Correct DEF tank mounting is a critical part of Tier 4 emissions system integrity; using the OEM band helps maintain proper SCR system function and avoids fault codes tied to DEF delivery issues.

The DEF (Diesel Exhaust Fluid) tank band is a retention bracket that secures the DEF tank firmly to the generator frame on Tier 4 Final diesel units. The DEF tank feeds fluid into the selective catalytic reduction (SCR) system, which reduces harmful NOx emissions to meet EPA Tier 4 standards — meaning the tank must stay securely mounted and free from vibration-induced stress at all times. When the band becomes damaged, corroded, or loses clamping force, the tank can shift, putting strain on DEF lines and fittings and potentially triggering emissions-related fault codes that shut the generator down.
