BM Catalysts can provide a wide variety of flexes to suit all applications. There are three different types of flex available. Our Standard Flex is suitable for nearly all applications and is available in many different lengths and bore sizes. The Inner Braided Flex can be used to counteract whistling problems, while our Strengthened Flex is especially suited to applications where there is a lot of movement through the flex.
