Polyurethane U-Seal, 2.50 Inch OD, 1.75 Inch ID, 0.38 Inch Height

Description & Features

Engineered for demanding hydraulic applications, the Polyurethane U-Seal is an essential component designed to maintain robust sealing integrity under high pressure. With an outer diameter of 2.50 inches and an inner diameter of 1.75 inches, this seal is crafted from durable urethane material, ensuring superior performance and longevity. It features a beveled lip design that effectively breaks the fluid film, enhancing sealing efficiency and reliability.

Capable of withstanding pressures up to 6,000 PSI and operating in temperatures ranging from -65°F to 220°F, this U-Seal is ideal for a variety of industrial applications. Its design, where the height exceeds the cross section, provides an optimized balance of flexibility and strength. Manufactured by Hercules Sealing Products, this seal meets high industry standards for performance and durability.

Question by: Danny H on Aug 27, 2025, 6:06 PM

Reckon this'll hold up in my hydraulic press? I'm pushin' it pretty hard sometimes.

Answer by: Customer Support on Aug 29, 2025, 11:42 AM

With a pressure rating up to 6,000 PSI, this U-seal should handle most hydraulic press applications, but be sure you don't exceed that pressure for the seal's longevity.
