The Multiquip EM400557 1/4" Orifice is a genuine OEM component designed for the FM9 finishing machine. As a direct OEM replacement, this part is sourced and approved by Multiquip to meet the exact specifications of your equipment. Confirm your model against the FM9 designation before ordering to ensure a correct match.
Key Features
- OEM-Specified Flow Diameter: — Manufactured to the exact 1/4" orifice dimension required for proper fluid or fuel metering in FM9 finishing machine applications.
- Genuine Multiquip OEM Part: — Sourced directly through Multiquip's parts program, ensuring material composition and dimensional tolerances match the original component.
- Direct Drop-In Replacement: — Engineered to seat and seal in the same position as the factory-installed orifice, requiring no rework to the surrounding assembly.
- FM9 Finishing Machine Fitment: — Confirmed compatibility with the Multiquip FM9 series finishing machine; always cross-reference your unit's parts documentation to verify applicability.
- Consistent Flow Control: — A correctly sized orifice maintains the calibrated flow rate the machine depends on; a worn or damaged orifice causes erratic output and inconsistent machine performance.
An orifice is a precision-machined restriction fitting that controls the rate at which fluid, fuel, or air passes through a line or port within a machine system. By maintaining a fixed, calibrated opening size, the orifice ensures that downstream components receive the correct volume and pressure of fluid for consistent operation. When an orifice becomes worn, corroded, or obstructed, flow rates shift outside of specification — leading to erratic performance, reduced output, or potential damage to connected components.
