A 175mm black twin wall 90° elbow is a bend that connects two sections of twin-wall flue pipe at a 90-degree angle, allowing for a directional change in the flue system. This type of elbow is commonly used in domestic heating and other applications where a twin wall flue is required.
Twin-wall flues are designed with two layers of stainless steel, providing insulation between the flue gases and the surrounding environment. This design helps prevent condensation and ensures proper flue performance, even in condensing applications.
