The Multiquip EM400689 5/8" Orifice is a genuine OEM replacement designed for the FM9 finishing machine. Sourced directly from Multiquip, this part meets the same specifications as the original component installed at the factory. It is a direct-fit replacement for FM9 units, making installation straightforward with no guesswork on sizing or compatibility. If your machine is showing signs of inconsistent flow or reduced output performance, replacing the orifice with the correct Multiquip EM400689 is the reliable solution.
Key Features
- Genuine OEM Construction — Manufactured to exact Multiquip specifications, ensuring the orifice diameter and material grade match the original FM9 component precisely.
- Exact 5/8" Bore Sizing — The fixed 5/8" opening installs as a direct drop-in replacement, maintaining correct flow calibration without adjustment or modification.
- Confirmed FM9 Fitment — Verified for compatibility with the Multiquip FM9 finishing machine, so you can order with confidence knowing this is the correct part.
- Consistent Flow Control — A correctly sized orifice keeps fluid or material delivery steady and controlled, protecting downstream components from pressure spikes or starvation.
- Fuel and Fluid System Integrity — On fuel or hydraulic circuits, a worn or damaged orifice can disrupt metered flow and cause hard starting, rough running, or uneven operation; replacing it restores proper system balance.
An orifice is a precisely sized restriction fitted into a fluid or fuel circuit to meter flow at a controlled rate. By limiting the volume passing through at any given moment, it regulates pressure and delivery to downstream components, keeping the system operating within its designed parameters. When an orifice becomes worn, corroded, or clogged, flow rate changes and the machine may exhibit erratic operation, loss of power, or uneven material delivery — making timely replacement critical to maintaining consistent performance on the FM9.
