Polyurethane U-Seal, 5.75 Inch OD, 5.00 Inch ID, 0.63 Inch Height

Description & Features

Manufactured from polyurethane by Hercules Sealing Products, this U-seal is suited for hydraulic cylinder and actuator applications requiring reliable sealing across a wide range of pressures and temperatures. The beveled lip design provides effective film breaking, and the height-greater-than-cross-section profile offers added sealing contact for demanding service conditions.

The Polyurethane U-Seal, 5.75 Inch OD, 5.00 Inch ID, 0.63 Inch Height carries a 5.75 in OD, 5.00 in ID, and a 0.625 in height with a 0.375 in cross section. Rated for pressures from 0 to 6,000 PSI and a temperature range of -65°F to 220°F, it is well-suited for hydraulic systems operating under variable thermal and pressure conditions. The urethane construction provides durability and resistance to wear in dynamic sealing environments.

Question by: Ronnie P on Sep 24, 2025, 3:55 PM

Got a 5-inch bore cylinder that needs a new u-seal. The old one's shot. This a straight swap for that size?

Answer by: Customer Support on Sep 26, 2025, 12:20 PM

For a 5.00 inch ID and 5.75 inch OD, yeah, that lines up for a standard 5-inch bore application. The height on this one runs 0.625 inches with a 0.375 inch cross section, so just confirm your groove dimensions match up before you put it in. The cross section being smaller than the height is by design on this particular seal, so it ain't a misprint if your reference shows both numbers.

got a cylinder gland that takes a 5 inch rod seal, is this the one with the 5.75 OD and 0.625 tall?

Answer by: Customer Support on Jun 23, 2025, 9:10 AM

Match it up by the dimensions: this U-seal is 5.00 inch ID, 5.75 inch OD, and 0.625 inch height, with a 0.375 inch cross section. It’s the Type B style where the height is greater than the cross section, and it has a beveled lip.
