The aFe Magnum FORCE straight reducing bellow coupler (3-1/8 in ID to 3 in ID, 3-1/2 in long) in red is a flexible bellows-style silicone connector that eases installation between slightly misaligned tubes. Its design allows expansion, movement and vibration and it is commonly used on aFe POWER intakes as a spare part. The reinforced silicone construction and included clamps provide a durable, corrosion-resistant joint for non-pressurized applications.
