Multiquip Y0377102270 DEF Hose - OEM Replacement Part for Super Silent Generators

This DEF (Diesel Exhaust Fluid) hose delivers urea solution from the storage tank to the SCR (Selective Catalytic Reduction) system in Tier 4 Final compliant super silent generators. Essential for emissions control, a deteriorated or cracked DEF hose can cause fluid leaks, DEF system fault codes, and generator shutdown. Replace this hose if you notice crystallized DEF residue around connections, soft or swollen rubber, or if the check engine light indicates SCR system issues.

Designed specifically for Multiquip's DCA125SSIU4F super silent generator, this hose features chemical-resistant materials that withstand the corrosive nature of diesel exhaust fluid and temperature extremes in the engine compartment. Regular inspection of DEF system components during routine maintenance helps prevent unexpected downtime and ensures compliance with emissions regulations.

Compatible with the following Multiquip generator models:

• DCA125SSIU4F
