Imagine the following unacceptable case study. An O-Ring is seated within an equally sized groove. What’s wrong with this picture? Well, the rubber won’t compress as it’s installed. Instead, the identically sized O-Ring and circular groove create a snug fit. An effective seal can never form. To create that seal, the cross-sectional width and depth […]
Extrusions are discharged through special die assemblies. The elastomers are loaded into extrusion machines, heated and forced at pressure, then they slide through the die section, where they’re shaped into a desired cross-sectional outline. Continuing outwards, like toothpaste from a tube, the die-profiled extrusions assume many functional shapes, including those that have edge trims. A […]
Full face gaskets are wide enough to cover an entire flange. That means the ring starts at the edge of the flange face, moves in towards the internal pipe diameter, and thus covers the whole seal surface. Securing bolts pass through the gasket, so there’ll be bolt holes included on the die-cut material. Talking of […]
Low-pressure pneumatic systems employ less than 75-kPa of pump compressed air. That figure can climb as high as a several hundred kilopascal load. For hydraulic equipment, the design engineer can easily pop another zero on the end of that number, for these heavy-duty systems are often asked to handle thousands of kilopascals, and those kinds […]
When seeking low-temperature gaskets, coolroom designers use their engineering skills to select suitable materials. A conventional sealing material, although compressible and surface conformable, isn’t necessarily good enough here, not if it becomes brittle when the temperature drops below zero degrees Celsius. Clearly, then, as well as all of the normal, highly desirable material compressibility features, […]
