About Rod & Piston U-Cup Seals

Also known as U-rings, these U-cup seals have flared edges, or lips, that effectively seal rods and pistons. Named after their U-shaped cross section, they can be used for static and dynamic applications.

Loaded U-rings have an O-ring filler, or energizer, that applies uniform contact to the flared edges to maintain sealing force at low and high pressures.

Use these T-shape rings on pistons to form a stable, square seal for low-pressure applications. They are designed to resist extrusion and to fit into existing O-ring grooves, allowing you to retrofit these rings without making changes to your hardware.
