How to Measure an O-Ring Correctly: ID, Cross-Section and Dash Sizes
Learn how to measure an O-ring correctly: inside diameter, cross-section, AS568 and JIS dash size matching, worn-seal cases and cord stock measuring.
Welcome to the BOSS Sealing Knowledge Base — a practical library of professional sealing know-how, written by our engineers. Here we share technical guides and field experience covering o-rings and hydraulic & pneumatic seals: material selection and comparison (NBR, FKM, EPDM, HNBR, silicone, PU, FFKM, FEP/PFA, PTFE, PEEK), seal design and groove dimensions, installation best practices, failure analysis, and international manufacturing standards such as ISO 3601, AS568 and JIS B 2401.
Whether you are an engineer specifying seals for hydraulic cylinders, a purchasing manager comparing encapsulated o-rings and spring energized seals, or a maintenance technician troubleshooting leaks, you will find clear, experience-based answers here. All articles are based on real production and application cases from our factory.
