Key Features
- Genuine OEM Sealing Material — Manufactured to the original material specification for this fuel injection application, maintaining proper compression and chemical resistance against fuel exposure.
- Direct-Fit Replacement — Seats correctly within the ES79 fuel injection assembly with no rework or adaptation required to the surrounding components.
- Confirmed ES79 Fitment — Verified OEM replacement for ES79 series equipment, so you can order with confidence that this is the correct washer for your machine.
- Fuel System Integrity — A properly functioning washer maintains a leak-free seal at the injection point; a damaged or missing washer can allow fuel to escape, disrupting injection pressure and engine performance.
- Fuel System Safety — Maintaining an intact seal in the fuel injection circuit is critical to preventing fuel leaks that can create fire hazards and unsafe operating conditions.
A fuel injection washer serves as a sealing element within the fuel injection assembly, preventing fuel from leaking past threaded or mating surfaces under the pressure generated by the injection system. This small but critical component keeps injection pressure consistent and the fuel circuit closed, which directly affects engine starting, idle stability, and power output. When this washer degrades, cracks, or is lost during service, fuel can seep past the joint, leading to rough running, difficult starts, and potential fire risk if fuel contacts hot engine surfaces.
