Even if machine elements under pressure are firmly bolted to one another, there is still a so-called static seal gap that must be sealed. O-Rings – or O-Rings with back rings for improved extrusion stability – are most commonly used. If the requirements are more specialized, one-piece sealing elements made of polyurethane come into use. For example, the requirements may involve gaps for breathing due to major pipe expansion, short pressure rise times or alternating operating pressures. MHEC offers the most suitable cover seal for any application. They stand for the highest possible operating security and extrusion stability.
