‌Gasket vs Seal: Comprehensive Technical Guide and Manufacturing Solutions‌

By YIDEXIN - ISO-Certified Rubber Components Specialist Since 2005

‌1. Core Definitions and Structural Differences‌

‌1.1 What is a Gasket?‌

A ‌gasket‌ is a static sealing component designed to prevent leakage between two stationary surfaces under compression. Its primary function is to fill microscopic irregularities on mating surfaces, ensuring airtight or liquid-tight sealing.

‌Key Features of Our Industrial Gaskets:‌

• ‌Material Versatility‌: Custom EPDM, silicone, or graphite formulations for chemical/thermal resistance1
• ‌Precision Engineering‌: Laser-cut designs with ±0.05mm tolerance for flange alignment
• ‌Applications‌: Widely used in food processing equipment (FDA-compliant), automotive exhaust systems, and oil refinery pipelines57

‌1.2 What is a Seal?‌

‌Seals‌ are dynamic components preventing fluid/gas transfer between moving parts (e.g., rotating shafts). Modern designs like ‌dry gas seals‌ revolutionize industrial applications by eliminating lubrication needs through spiral groove technology23.

‌Our Seal Manufacturing Capabilities:‌

• ‌High-Speed Solutions‌: Tested at 15,000 RPM under 10MPa pressure for centrifugal compressors28
• ‌Material Innovation‌: Proprietary HNBR compounds with 98% wear resistance improvement over standard NBR
• ‌Industry-Specific Designs‌: Hydraulic cylinder seals with integrated PTFE backup rings
