The Multiquip 1574860570 is a genuine OEM Orifice Assembly designed for DAW-500S welders and DCA15SPX3 and DCA10SPX3 diesel-powered generators. As a direct OEM replacement sourced through Multiquip's authorized parts network, this assembly delivers the calibrated flow characteristics the original design requires. Verified fitment across the DAW and DCA generator families means you can order with confidence and install without guesswork.
Key Features
- Calibrated Flow Precision — Manufactured to OEM specification for consistent fluid or fuel passage, maintaining the metered flow rate the engine and fuel system depend on.
- Genuine OEM Part — Sourced directly from Multiquip, ensuring the orifice bore diameter and material match the original component exactly as fitted at the factory.
- Drop-In Assembly Format — Supplied as a complete assembly, so installation connects directly to the existing fuel or hydraulic line without additional machining or adapters.
- Confirmed Fitment — Compatible with DAW-500S welders and DCA15SPX3 and DCA10SPX3 diesel-powered generators within the Multiquip equipment range.
- Fuel System Integrity — A correctly sized orifice keeps fuel delivery consistent and protects downstream components; a worn or damaged orifice causes erratic flow, hard starting, and uneven power output.
- Fuel System Safety — Using the correct OEM-rated orifice assembly helps prevent uncontrolled flow conditions that can pose a fuel system hazard on generator and welder applications.
An orifice assembly is a precisely sized flow-control component installed within a fuel or fluid circuit to regulate the volume and pressure of liquid passing through it at any given moment. By maintaining a fixed, calibrated bore, it ensures the engine or system receives a consistent, metered supply rather than an unrestricted flow that could flood or starve critical components. When an orifice becomes worn, corroded, or blocked, the result is inconsistent fuel delivery, rough running, difficulty starting, or in severe cases, component damage caused by pressure imbalance in the line.
