Manufactured from Buna-N elastomer, this 1-inch gasket is designed for use within Aeroquip Flexmaster tube and pipe joint assemblies. Buna-N construction provides reliable sealing performance across a working temperature range starting at -25°F, making it well suited for hydraulic fluid service in industrial line and hose connections.
The Danfoss / Eaton Flexmaster Buna Gasket is a direct-fit replacement component for Flexmaster-style couplings, with both end sizes rated at 1 inch for line, hose, and tube configurations. Fluid compatibility documentation is available from Eaton for reference when confirming suitability with specific media.
Will this gasket hold up to hydraulic fluid alright?

Buna-N provides reliable sealing performance when used with hydraulic fluids, and it's rated down to -25°F for colder applications. Eaton has fluid compatibility documentation available if you want to confirm it for a specific fluid type.
