Designed for use in hydraulic tube and pipe joint assemblies, this Aeroquip Flexmaster gasket is constructed from Buna-N, making it well-suited for applications requiring resistance to petroleum-based hydraulic fluids. The 0.75-inch end size on both connections is consistent with standard line, hose, and tube terminations commonly found in industrial hydraulic circuits.
The Danfoss / Eaton Flexmaster gasket carries a minimum working temperature rating of -25°F, supporting use in cold-environment installations where seal integrity under thermal stress is a consideration. Fluid compatibility documentation is available through Eaton's published resources, providing guidance on approved media for this elastomeric seal type.
Will this gasket hold up with standard hydraulic fluid, or do I need something special?
