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
Example: The part number 823-O signifies an 8 gauge insulator, two holes, three inches long, oval in shape.
