O-Ring Cord Technical & Selection Guide
Choose the right cord, understand sizing, and avoid sealing problems.
Round Cord (Inch)Standard AS568 sizes for general sealing applications. The most common and versatile option. | Round Cord (Metric)Metric cross sections for international equipment and precision applications. |
Square CordIdeal for static sealing where increased surface contact improves performance. | Quad Ring CordX-profile design reduces friction and improves sealing in dynamic applications. |
O-Ring Cord TolerancesUnderstand diameter variation, splice tolerances, and how they affect sealing performance. | Spool LengthsStandard spool sizes, cut lengths, and how to order the right quantity. |
Material GuideCompare Buna, Viton®, EPDM, Silicone, and more based on temperature and chemical exposure. | Cord vs Molded O-RingsKnow when to use cord and when a molded O-Ring is the better solution. |
Splicing GuideLearn how to create O-Rings from cord using adhesives or vulcanizing. | Groove DesignCompression, stretch, and gland design guidelines for reliable sealing. |
Chemical ResistanceSelect the right material based on fluid compatibility and environment. | Measurement GuideMeasure cord diameter correctly and avoid sizing mistakes. |
