In heavy machinery and hydraulic presses operating above 250 bar, sealing reliability determines system performance. The critical question: Are compound seals (like Glyd Rings) more reliable than traditional single seals?   Single Seals: Three Fundamental Limitations   Standard O-rings and U-cups struggle in high-pressure environments for three reasons: Extrusion: High pressure forc...

Spring energized PTFE seals are widely used in applications where conventional sealing solutions cannot meet performance requirements. By combining a low-friction PTFE sealing jacket with a metal spring energizer, these seals provide consistent sealing force across a wide range of pressures, temperatures, and media.   But where are they most commonly used, and why are they preferred in t...
