In a marine environment, water ingress is an ever-present threat. A quality EP 80 lubricant is designed with:

But what makes this specific grade so vital for sub-surface operations? 1. Built for the "Extreme" in Extreme Pressure In a marine environment, water ingress is an
meet stringent military specifications (such as MIL-PRF-17331L) required for Navy vessels and submarines. These oils must maintain a high viscosity index, meaning they stay thick enough to protect gears at operating temperatures but fluid enough to flow instantly during a cold start in frigid waters. 3. Fighting the Constant Threat: Corrosion and Foam Under intense pressure
: Rapidly moving gears can whip air into the oil, creating foam that lacks lubricating power. EP additives include anti-foaming agents to ensure a solid film of protection stays on every gear flank. The Bottom Line
: It separates readily from water, allowing moisture to be drained away rather than letting it circulate and cause rust.
Standard oils can shear or thin out when subjected to the high torque and shock loads found in marine reduction gears. EP 80 lubricants are formulated with sulfur-phosphorus additives that form a "sacrificial" chemical layer on metal surfaces. Under intense pressure, this layer protects gear teeth from welding together or scuffing, ensuring smooth power transfer even during rapid maneuvers. 2. Specialized for Submarine Specs Not every gear oil can go deep. High-tier options like Chevron GST 2190 EP Go to product viewer dialog for this item.
