Garlock's BLUE-GARD 3300 for Cold and Refrigeration

In the late nineteenth century, Garlock devised a better way to seal piston rods in steam engines. Since then, sealing materials have been developed for specific various industrial applications. Over the years, different manufacturing processes such as calendering and beater addition have improved the performance of fiber sheet gaskets for these applications; however, design concepts for their formulation remain similar regardless of manufacturing
