MEC seal is short for Metal End Cap Seal, and it is the seal bonded the metal end cups on elastomer, which can provide a high level of extrusion resistance and metal to metal sealing. MEC seal is designed for EOG applications in harsh conditions, particularly for high pressures and high temperatures. Usually the elastomer can be HNBR, FKM, Aflas which depends on the application, and the material o...
Every machine or system that relies on seals understands the seriousness of a leak or premature seal failure. The subject involves significant financial, operational, and sometimes environmental issues that require in-depth understanding. The Basics of Seal Leakage What is Seal Leakage?: Beyond the basic definition, seal leakage can be understood as any unintended escape of fluid or gas due to the...
PDR rotary shaft seal extends the boundaries of elastomeric radial shaft seals, utilizing advanced materials and design techniques to provide optimal sealing performance for each application. The result is a superior sealing solution that retains a compact sealed casing. Due to the inherent limitations of various elastomer grades, the application range of standard elastomer rotary shaft seals is l...
