The Multiquip 4B1010 is a genuine OEM Urea Water Tank Hose designed for the DCA400SSI4F series super-silent diesel generators, including the DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, and DCA400SSI4F3PD variants. As a factory-original component, part 4B1010 delivers the exact material grade and dimensional fit required for proper DEF (Diesel Exhaust Fluid) fluid routing in Tier 4 emissions-compliant generator systems. Sourcing the correct OEM hose ensures the urea delivery circuit operates as engineered, protecting the SCR emissions system and keeping your generator in regulatory compliance. DHS Equipment stocks this Multiquip part ready for your next scheduled service or emergency repair.
Key Features
- OEM-Grade Fluid Compatibility — Manufactured to resist DEF/urea solution degradation, maintaining hose integrity over extended service cycles in demanding generator applications.
- Direct-Fit Routing and Connections — Engineered to the original hose path and end fittings of the DCA400SSI4F platform, allowing a straightforward swap without rerouting or adapter fittings.
- Confirmed Fitment for DCA400SSI4F Variants — Compatible across DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, DCA400SSI4F3PD, and related super-silent diesel generator configurations.
- Protects SCR System Function — A correctly routed urea hose ensures consistent DEF delivery to the selective catalytic reduction system, preventing fault codes, derate conditions, and emissions non-compliance.
- Emissions System Compliance — Proper DEF hose condition is a requirement for Tier 4 Final emissions compliance; using the correct OEM replacement supports continued legal operation of your generator.
The urea water tank hose routes diesel exhaust fluid from the DEF storage tank to the selective catalytic reduction (SCR) system, which reduces harmful nitrogen oxide emissions in Tier 4 Final diesel engines. Without a properly functioning hose, DEF flow can be interrupted, triggering engine derate warnings or a full shutdown to protect emissions compliance. A cracked, kinked, or deteriorated hose is one of the most common causes of SCR-related fault codes on Tier 4 generator sets, making timely replacement critical to uninterrupted operation.
