Insulation and Insulators  Insulation and Insulators

Richards Ceramic Insulators are made from the highest quality raw materials and carefully blended for superior mechanical strength, re- sistance to thermal shock and excellent insulating properties at high temperatures. Strict attention to hole size, wall thickness, and other details result in minimum breakage during installation. Our oval type insulators are designed to allow two thermocouples to be installed in a single protection tube. The part numbers below , and on the next two pages, describe the physical dimensions of the insulators , and on the next t o pages, describe the physical dimensions of the insulators
