Multiquip HBL5278C Inlet Flange

The Multiquip HBL5278C Inlet Flange is a genuine OEM component designed for DCA series Super-Silent and diesel-powered generators, including models DCA150SSJU4F3, DCA180SSJU4F3, DCA20SPXU4F, DCA220SSJU4F, DCA300SSJU4F2, DCA300SSJU4F3. As a direct OEM replacement, the part is manufactured to the same specifications as the original part, ensuring a proper fit within the generator's fluid or air intake system without the need for modification. DHS Equipment supplies this part direct from Multiquip's authorized parts network, so you can order with confidence that you're receiving the correct component for your machine.

Key Features

• Genuine OEM Construction — Manufactured to original Multiquip tolerances, ensuring the flange seats and seals correctly within the intake system of your DCA generator.
• Drop-In Fitment — Matches the original mounting pattern and port dimensions, allowing straightforward installation on compatible DCA series units.
• Broad DCA Series Compatibility — Fits a wide range of Super-Silent and diesel-powered DCA generators, including DCA45SSIU4F, DCA70SSJU4F, DCA180SSJU4F, DCA300SSJU4F, DCA400SSI4F3, DCA600SSV4F3, and more.
• Intake Integrity — A properly seated inlet flange maintains a leak-free connection at the intake junction; a cracked or warped flange can allow unmetered air or fluid ingestion, disrupting generator output stability.
• Authorized OEM Source — Sourced through Multiquip's authorized parts channel, confirming part number this part is the correct, current OEM reference for this application.

The inlet flange is a structural connection point that joins an intake line or duct to the engine or system housing on the generator. It provides a rigid, sealed interface that keeps the intake path closed to contaminants and maintains consistent flow into the system. When an inlet flange cracks, warps, or develops a compromised seal, it can introduce uncontrolled air or allow fluid loss at the junction — leading to rough running, output inconsistency, or accelerated wear on connected components.
