Vibrant Performance Aramid Reinforced Silicone Hump Hose Couplers feature a single-arch bellow design. This coupler is intended for use in applications where pressurized tubing and connection points are exposed to minimal movements or misalignment (eg. shearing, extension, compression). Our Hump Hose couplers are commonly found off of turbo compressor housings, intercooler end tanks and charge pipe assemblies.
