The Multiquip EM400690 3/4" Orifice is a genuine OEM component designed for the FM9 finishing machine. Sourced directly from Multiquip, this orifice matches the original part in size, material, and flow specification — ensuring a correct, drop-in replacement every time. If you're servicing an FM9 and need a dependable replacement, the EM400690 is the exact part Multiquip specifies for this application.
Key Features
- Genuine OEM Precision: — Manufactured to the original bore diameter and material spec, so fluid flow rate and pressure behavior remain consistent with factory design intent.
- Direct Replacement for FM9: — Engineered specifically for the Multiquip FM9 finishing machine, this orifice installs in place of the original without any modification to surrounding fittings or lines.
- Correct Flow Control: — A properly sized orifice regulates fluid or fuel delivery at the correct rate; an undersized or oversized unit will cause the machine to run lean, rich, or erratically.
- Verified Part Number: — The EM400690 is the Multiquip-assigned part number for this orifice, removing guesswork when sourcing a replacement during service or repair.
- Durable Construction: — Built to withstand the operating pressures and fluid exposure conditions of the FM9, helping the orifice hold its calibrated opening over extended service intervals.
An orifice is a precisely sized opening in a fluid or fuel circuit that controls the rate at which a liquid or gas passes through a line or passage. By restricting flow to a calibrated diameter, it regulates pressure and delivery volume to downstream components — keeping the system operating within its intended parameters. When an orifice becomes worn, clogged, or damaged, flow becomes inconsistent, which can cause poor performance, erratic operation, or component damage further along the circuit.
