An automotive flex pipe, also known as a bellows, is a type of flexible exhaust connector that is designed to absorb vibration, thermal expansion, and movement between exhaust system components. It typically consists of a corrugated metal tube surrounded by an outer braid, and is installed between the exhaust manifold and the rest of the exhaust system. The flex pipe helps to reduce stress on the exhaust system and improve overall performance and longevity.Our main products are: Auto Exhaust Flexible Pipe, the Divider Type Petroleum Storage tank Central Drainage Device, Metal Expansion Joints, Thickened Oil Steam Injection Pipeline Wellhead Compensator Device, Metallic Flexible Hose, ect.
