Multiquip 4B1010 Urea Water Tank Hose - OEM Replacement Part

The urea water tank hose is a critical component in diesel exhaust fluid (DEF) delivery systems for Multiquip super silent generators equipped with selective catalytic reduction (SCR) emissions control. This hose transports urea solution from the tank to the exhaust treatment system, ensuring proper NOx reduction and emissions compliance.

Designed specifically for Japanese-market generator configurations, this OEM hose is engineered to handle the corrosive nature of urea solutions while maintaining flexibility across operating temperatures. Regular inspection of fuel and fluid hoses is part of standard maintenance protocols—technicians should check for signs of wear, deterioration, or hardening that could compromise system integrity. Failed or degraded urea hoses can lead to emissions system faults, reduced SCR performance, and potential engine derate conditions.

This hose is compatible with the following Multiquip super silent generator models:

• DCA400SSI4F
• DCA400SSI4F3B
• DCA400SSI4F3PD
