What kind of temperatures can this seal handle? I work in a pretty hot environment.
Question by: Keith C on Oct 4, 2025, 9:12 PM
This urethane U-cup seal is rated for temperatures ranging from -65°F to 220°F.
Answer by: Customer Support on Oct 6, 2025, 7:38 AM
seal measures 1.50 OD and 1.06 ID -- does that deep profile actually make a difference in how stable it sits in the groove compared to a standard cut?
Question by: Norm F on Jun 8, 2025, 5:29 PM
With a height of 0.3125 inches against a cross section of 0.1875 inches, the height runs taller than it is wide. That extra depth gives the seal more contact area along the groove wall, which translates to better resistance against tipping or cocking under side loads. A standard type seal where height and cross section are equal just doesn't have that same resistance to movement once pressure starts cycling. For hydraulic cylinder and actuator work where you're dealing with dynamic conditions, that added stability matters more than it might seem on paper.
