A kiln’s tube assembly is an important part that inserts into the kiln to hold and position a cone within a kiln sitter. There are two types of tube assemblies: Type-P and Type-K. Type-P tube assemblies are suited for P and LT-3 kiln sitters, while Type-K tube assemblies work with K and LT-3K kiln sitters. If you know the model of your kiln sitter, then determining the type of tube assembly you need is easy.


Tube assemblies come in a variety of lengths, so it is important that you purchase the correct size for your kiln. In order to make sure you are ordering the correct one, please disconnect and measure your tube assembly from the timer box before ordering. If you have any questions regarding which parts you need, please feel free to contact us.


Please see the products below for information on different types of tube assemblies and instructions on how to measure them.
