Question by: Lance B on Mar 19, 2026, 7:43 AM
Will this fitting handle hydraulic fluid in a marine application without corroding?
Answer by: Customer Support on Mar 20, 2026, 2:58 PM
Given its Eaton Aeroquip brand and applications listed for marine environments, this steel adapter should hold up fine with hydraulic fluid in marine settings. Just be sure to check the linked fluid compatibility document to verify suitability with the specific fluid you intend to use.
