Straight Assemblies - Double Tube -Types E, J, K & N - Standard Head, Aluminum

The Richards Double Tube Thermocouple Assemblies are designed for severe service applications. The double tube assemblies with a metal outer tube are for applications where mechanical damage and thermal shock to the thermocouple is a problem. The double tube assemblies which have a Silicon Carbide outer tube are for applications where thermal shock and flame contact is a problem. Double ceramic tube assemblies are for extra protection against corrosive atmospheres. We offer many other combinations of double tubes, which we could not list in this catalog due to space limitations. Richards double tube assemblies can be made from any type of metal or ceramic tube, which is available. ! Note: If you would like to order a Type E, J, or Type N assembly, just substitute the K with an E, J, or N in the part numbers listed on this page. Triple tube assemblies are also available.
