Description
The D-Ring Seal is a high-performance, bidirectional sealing element designed for both piston (OD sealing) and face (axial sealing) applications. Featuring a distinctive “D-shaped” cross-section, this seal combines the compression characteristics of a standard O-ring with the stability and wipe-action of a rectangular seal.

D-Shaped Cross-Section: A flat sealing surface for stable contact, combined with a curved, radiused base for uniform compression.
Asymmetric Profile: Optimized to maximize sealing efficiency while minimizing installation rolling.
Single-Component Design: Manufactured as a homogeneous unit from advanced elastomeric compounds.Original source: Hydraulic seal https://www.bszzseal.com/
