Enviro Blend 558 is a non-toxic high performance valve lubricant grease engineered for superior performance with valves & bearings in contact with water. This product is suitable for use in environmentally sensitive areas. Environmentally, Enviro Blend 558 has passed both protocols of the US Environmental Protection Agency for determining environmentally safe ‘fluids.” In the Acute Toxicity to Mysidopsis Bahia (“Shrimp Test”), the LC-50 value necessary to pass the minimum EPA requirement is 30,000 ppm of sample in the water for 96 hours. Enviro Blend 558 achieved a LC-50 value of greater than 1,000,000 ppm because not one shrimp was dead in a maximum concentration of Enviro Blend 558. In the Static Sheen Test, Enviro Blend 558 caused no sheen, iridescence, gloss or increased reflectance on the surface of the test seawater, demonstrating that Enviro Blend 558 contains no free oil, making it environmentally friendly to natural waters.
