Multiquip EE58497 DEF Heated Hose Pressure Line - OEM Replacement Part

This DEF (Diesel Exhaust Fluid) heated hose pressure line maintains proper fluid temperature and flow in the selective catalytic reduction (SCR) system of diesel generators operating in cold environments. The heated design prevents DEF from freezing or crystallizing, which can cause system blockages, performance issues, and engine shutdowns in temperatures below 12°F (-11°C).

As a critical emissions control component, this pressure line ensures continuous DEF delivery from the tank to the dosing injector. When this hose fails, operators typically experience DEF system fault codes, reduced engine power (derate), or complete shutdown to protect the emissions system. The integrated heating element maintains DEF in liquid state during cold weather operation, preventing costly downtime and ensuring regulatory compliance.

Compatible with the following Multiquip generator models:
