Key Features

• Genuine OEM Construction — Manufactured to the precise material and dimensional tolerances required for the oil filter circuit on the DCA-45USJ 4JG1 engine platform.
• Direct-Fit Installation — Engineered as an exact replacement for the original plug body, seating and sealing correctly in the oil filter housing without adaptation.
• Confirmed Fitment — Specifically validated for the Multiquip DCA-45USJ ultra-silent generator equipped with the 4JG1 diesel engine.
• Maintains Oil System Integrity — A correctly fitted plug body keeps the oil filter circuit sealed under operating pressure, preventing oil loss and protecting engine lubrication.
• Leak Prevention — A worn or damaged plug body can allow oil to bypass or weep from the filter housing; replacing it with a genuine OEM part restores a proper, pressure-rated seal.

The plug body is a structural and sealing component in the oil filter assembly, holding the filter element securely in place and maintaining a leak-free connection within the engine's lubrication circuit. On the 4JG1 diesel engine used in the DCA-45USJ, this plug body must maintain a reliable seal under sustained operating pressure to ensure oil flows correctly through the filter and back into the engine. If the plug body cracks, strips, or develops a compromised seal, oil pressure can drop and contaminated or unfiltered oil may circulate through the engine, accelerating wear and risking mechanical damage.
