The O-Ring Compression Ratio Calculator is a practical engineering tool designed to calculate O-ring squeeze and compression percentage based on seal cross-section and groove dimensions. By entering key parameters such as O-ring diameter, groove depth, groove width, and sealing configuration, users can quickly evaluate compression levels and sealing suitability. The O-Ring Compression Ratio Calculator supports hydraulic, pneumatic, automotive, and industrial seal design while helping engineers reduce leakage, excessive deformation, friction, and premature O-ring failure.
