seal's rated up to 6,000 PSI, that work for a mid-range hydraulic cylinder application, or is that pushing it?
Question by: Shawn B on Nov 4, 2025, 2:10 PM
For mid-range hydraulic cylinder work, 6,000 PSI is actually on the higher end of what most systems demand, so you've got plenty of headroom. The polyurethane construction handles pressure well in those kinds of dynamic environments, and the beveled lip design helps maintain a clean seal film even under load. Just make sure your bore and rod dimensions line up with the 2.25-inch OD and 1.875-inch ID before ordering.
