Key Features
- OEM-Grade Sealing Material — Manufactured to the precise compression and material specification required for the DCA85SSJU oil cooler interface, ensuring a leak-free seal under operating temperatures and pressures.
- Direct-Fit Replacement — Engineered to seat correctly against the oil cooler mating surface on the DCA85SSJU, installing exactly like the original with no trimming or modification.
- Confirmed Fitment — Verified for the Multiquip DCA85SSJU ultra-silent diesel generator series.
- Prevents Oil Contamination and Cooler Bypass — A properly seated oil cooler gasket maintains the sealed cooling circuit, keeping engine oil and coolant in their correct flow paths and preventing cross-contamination or pressure loss.
- Critical Leak-Point Protection — A failed oil cooler gasket can allow oil or coolant to escape the sealed system, leading to overheating, oil loss, and potential engine damage — making timely replacement essential for safe generator operation.
The oil cooler gasket forms the sealing interface between the oil cooler and its mating surface on the engine or cooler housing. Its job is to maintain a pressure-tight barrier that keeps engine oil and coolant separated and contained within their respective circuits as they pass through the cooler. When this gasket deteriorates, cracks, or is compromised during service, it can allow fluids to leak externally or mix internally — either of which can cause overheating, lubrication failure, or serious engine damage. Replacing a worn oil cooler gasket promptly with the correct OEM part is one of the most cost-effective ways to protect the longevity of a diesel generator.
