This is a flexible tube made of austenitic stainless steel. Its flexibility protects piping from potential fractures caused by the settling of masonry structures. KEOKLE simplifies the installation of meters, which are often placed in very tight spaces. The KL980165/66/67/68/69/ models all feature gas-contacting parts made of austenitic stainless steel, and the tube is extendable.
