Parts are available to help you keep your Kiln Sitter in good working order. We have a variety of different tube assemblies. Selecting the right one for your kiln sitter is important to help ensure you get the replacement tube assembly you need please provide part number of your tube at checkout. All tube assemblies are made with a bracket that attaches to the kiln sitter faceplate. We have both a short bracket (1” additional length added to the ceramic tube length) and a long bracket (2.5” additional length added to the ceramic tube length) to make the tube assemblies. The part numbering system for tube assemblies Consists of a Letter and a Number. The letter is either an “S” or an “L” which designates whether you have a Short or Long Bracket. The number designates the overall length to the nearest ½”.
