Question by: Wes R on Aug 13, 2025, 7:16 AM
does this plug work if the system's already got pressure in it, or do you have to bleed it down first?
Answer by: Customer Support on Aug 14, 2025, 4:46 PM
You can connect it while the system is still pressurized, up to 500 psi. That connect-against-pressure capability is built into the 5100 series design, so there's no need to depressurize the line before making the connection. That saves real time on the job when you're working with live systems.

Will this plug hold up okay in a hydraulic system that sees a lot of use, day in and day out?

Eaton designed this dust plug with robust materials, including brass and steel, intending for it to withstand frequent connections and disconnections.
