The Multiquip RE560898 DEF Pressure Line is a genuine OEM component designed for DCA150SSJU4F and DCA220SSJU4F series super-silent generators. As a direct OEM replacement, this line is built to the same specifications as the original, ensuring proper DEF delivery and Tier 4 emissions system integrity. Confirmed fitment covers DCA150SSJU4F and DCA220SSJU4F models, including 60Hz configurations.
Key Features
- Genuine OEM Construction — Manufactured to the original pressure and chemical-resistance specifications required for DEF fluid handling, ensuring the line maintains structural integrity under operating temperatures and pressures.
- Direct-Fit Replacement — Engineered to connect at the factory-defined routing points on the DEF system, allowing straightforward installation without rerouting or adapting fittings.
- Confirmed Fitment — Compatible with DCA150SSJU4F and DCA220SSJU4F super-silent generator models, including 60Hz variants.
- Emissions System Performance — A properly functioning DEF pressure line maintains consistent fluid flow to the SCR system, supporting clean Tier 4 compliance and preventing fault codes that can limit generator output or trigger shutdowns.
- Emissions and Regulatory Compliance — The DEF delivery system is a regulated emissions component; using a genuine OEM line helps ensure your generator continues to meet Tier 4 Final emissions requirements without interruption.
The DEF pressure line carries diesel exhaust fluid from the DEF tank to the selective catalytic reduction (SCR) system, where it is injected into the exhaust stream to reduce nitrogen oxide (NOx) emissions. This line must maintain a consistent, leak-free flow at system pressure — any cracking, blockage, or fitting failure can interrupt DEF delivery, triggering fault codes and potentially placing the generator into a derated or shutdown condition. On Tier 4 Final machines like the DCA150SSJU4F and DCA220SSJU4F, a compromised DEF line can directly affect both power output and regulatory compliance.
