Zinc Free / Biodegradable Hydraulic Oil

Biodegradable Hydraulic Oil and/or Zinc-Free Hydraulic Oils provide exceptional performance while exceeding environmental regulations adopted by the U.S. Fish and Wildlife Service and the U.S. EPA.

Whether you are operating industrial equipment in an environmentally-sensitive area, OR, your system requires a non-zinc hydraulic fluid*, Petroleum Service Company offers a Zinc Free/Biodegradable Hydraulic Oil for your application.

If choosing a biodegradable hydraulic fluid or zinc-free hydraulic fluid in order to comply with an environmental regulation, make sure to review the hydraulic fluids product data sheet for specifications because there are varying degrees of biodegradability that need to be considered.

*Zinc, a common sacrificial additive in hydraulic lubricants, may be corrosive to silver and yellow metals and, as such, not applicable to all industrial and mobile machines. Additionally, additives with high zinc levels (above 700 ppm) are not biodegradable and potentially harmful to fish and aquatic species. Check manufacturer specifications to determine if a zinc-free hydraulic oil is applicable to your use.
