Categorized by the U.S. EPA in the most favorable classification as environmentally acceptable lubricants (EALs), these polyalkylene glycol (PAG)-based hydraulic and gear fluids are non-sheening, heavier than water, and water-soluble. The EPA’s 2013 Vessel General Permit (VGP) mandates that vessel owners/operators convert oil-to-sea interfaces (propulsion systems) from toxic petroleum oils to EALs. Neptune® AW and Neptune® Gear lubricants from ACT are “Readily Biodegradable” according to OECD 401F, classified as “Relatively Harmless” or “Practically Non-toxic” to aquatic life by the U.S. Fish and Wildlife Service, and are the only EALs that are truly non-sheening in the event of a leak or spill, passing the 40 CFR 435 Static Sheet Test to comply with provisions of the EPA Clean Water Act.
Neptune® water soluble PAG’s are inert to water and will perform without issue in demanding marine applications where water ingress is likely. These highly stable synthetic fluids drive value by significantly extending drain intervals. Users of Neptune® AW and Neptune® Gear lubricants benefit from reliable performance similar to that of petroleum lubricants, and enjoy the peace of mind that come from knowing that, in the event of a leak, the lubricant keeps them off the radar screen of regulatory bodies and out of harm’s way.
