The Multiquip 4B1016 is a genuine OEM Urea Water Tank Hose designed for the DCA400SSI4F series super-silent diesel generators, including the DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3B, DCA400SSI4F3PB, and DCA400SSI4F3PD variants. As a factory-sourced component, the part delivers an exact fit with no guesswork on compatibility or installation. This hose is a direct replacement that keeps the DEF (diesel exhaust fluid) system operating correctly, maintaining Tier 4 emissions compliance on your generator. DHS Equipment stocks this genuine Multiquip part so your DCA400SSI4F series machine gets back to work with the right component the first time.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specs for the DEF/urea routing system, ensuring proper fluid compatibility and pressure retention.
- Direct Drop-In Replacement — Engineered to connect at the same routing points as the original hose, allowing straightforward installation on DCA400SSI4F series generators.
- Broad DCA400SSI4F Series Coverage — Fits DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3B, DCA400SSI4F3PB, and DCA400SSI4F3PD models, including Sunbelt-designated units.
- Emissions System Integrity — A sound urea hose is critical to maintaining proper DEF delivery to the aftertreatment system; a cracked or leaking hose can trigger fault codes and force the unit offline.
- Tier 4 Compliance Support — Keeping the DEF circuit intact ensures the generator continues to meet EPA Tier 4 Final emissions requirements expected on regulated jobsites.
The urea water tank hose routes diesel exhaust fluid (DEF) from the storage tank to the aftertreatment system on Tier 4 Final diesel generators. This fluid is injected into the exhaust stream to reduce nitrogen oxide (NOx) emissions, and the hose must maintain a leak-free seal to keep the system functioning correctly. A deteriorated or cracked hose can restrict DEF flow, trigger emissions-related fault codes, and ultimately force the generator into a derate or shutdown condition.
