It shows the critical dimensions linked to the specification tables, such as the inside diameter (\u00d8d), the outside diameter (\u00d8D), the seal cross-section width (b), the housing groove width (B) and the lead-in chamfer length (C), together with the groove root fillet radii and the 20\u00b0 lead-in angle. Working to these dimensions ensures accurate positioning, installation without distorting the profile and optimum static and dynamic sealing performance in double-acting applications at medium and high pressures.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t \n\t\t\t\t \n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t $\"\"$ \t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t \n\t\t \n\t\t\t\t \n\t\t\t\t \n\t\t\t\t\tThree-dimensional view and components of the HB symmetrical seals<\/span>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t \n\t\t\t\t \n\t\t\t\t\t\t\t\t\tThis 3D illustration shows the basic structure of the HB symmetrical seal in detail. You can clearly see its two key elements: the polyurethane body with symmetrical sealing lips and the energizing O-ring, which provides the permanent radial load. Its compact design and reversible geometry allow it to be used either as a rod seal or as a piston seal, providing effective sealing and simple snap-on installation.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t \n\t\t\t\t \n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t $\"\"$ \t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t \n\t\t\t\t \n\t\t\t\t \n\t\t\t\t\t
