Multiquip EM400554 5/8" Orifice

The Multiquip EM400554 5/8" Orifice is a genuine OEM replacement designed for the FM9 finishing machine. Sourced directly from Multiquip, this part meets the original design specifications for the FM9, ensuring proper fluid or material flow control within the system. If you're servicing or rebuilding your FM9, part number EM400554 is the correct factory-specified component for the job.

Key Features

• Genuine OEM Specification: — Manufactured to the exact bore diameter and material grade required for consistent, calibrated flow control in the FM9 finishing machine.
• Direct Drop-In Replacement: — Engineered to seat and seal in the original orifice port without reworking or adapting the surrounding assembly.
• FM9 Verified Fitment: — Confirmed compatible with the Multiquip FM9 finishing machine; use part number EM400554 to ensure you're ordering the correct size and spec.
• Precise Flow Control: — A correctly sized 5/8" orifice maintains the intended pressure and flow rate through the system; an incorrect or worn orifice can disrupt machine operation and affect output quality.
• Fuel and Fluid System Integrity: — As a metering component in a pressurized system, an OEM-spec orifice helps maintain safe, designed operating pressures — a non-spec substitute can cause irregular system behavior.

An orifice is a precisely sized restriction fitting installed within a fluid or fuel delivery system to meter flow at a controlled rate. The fixed bore diameter — in this case 5/8" — determines how much fluid passes through at a given pressure, directly influencing how the downstream system performs. When an orifice becomes worn, corroded, or is replaced with an incorrect size, flow rates shift outside the designed range, which can cause inconsistent machine behavior, pressure irregularities, or component wear elsewhere in the system.
