Product Questions & Answers

Part number 16004-403, that's the o-ring for a Danfoss piston pump, right? Just want to make sure I'm ordering the right thing before I pull the trigger.

Yeah, that part number lines up with the Danfoss / Eaton piston pump accessory o-ring. It's sold as a single o-ring per unit, so if you've got the 16004-403 listed as the part you need, you're in the right place. Worth double-checking your pump model against the size you need, since this o-ring is available across multiple configurations and sizes to fit various piston pump models.
