what seal materials come standard on these dust caps? trying to figure out if Buna-N is gonna hold up with what we're running through the lines
Question by: Sheila C on Jun 12, 2025, 7:45 AM
Buna-N is one of three standard seal options available on the 5600 Series. EPR and Viton are the other two. All three come as standard materials, so depending on what fluid you're running, there's likely already a compatible option in the lineup without needing a special order.

got a -04 Hansen FD72/FD76 quick disconnect on a hose, is this the right dust cap for it?

For a -04 coupling size in the Danfoss and Eaton Hansen FD72/FD76 family, this part is the matching 5600 Series industrial interchange dust cap.
