Hump Hose Couplers

A hump hose has a raised bellows section in the middle that flexes, which lets it soak up engine rock and vibration that would otherwise stress pipes, clamps and intercooler tanks. This collection covers the Vibrant Performance silicone hump hose couplers, mostly in 3 inch inside diameter with a few larger sizes, in black and blue.

Where hump hoses help

Use a hump hose where an engine-mounted part connects to a chassis-mounted part, like a turbo outlet to a front mount intercooler pipe or an intercooler pipe to a throttle body. The hump flexes so the straight joints do not have to.

Single and multi hump

One hump handles moderate movement. Larger misalignment or engines with soft mounts may call for a longer hose or a second hump.

Common questions

Will the hump balloon under boost? Reinforced construction keeps it stable at normal boost levels.

Does a hump hose replace a torque strap? No. It absorbs vibration, but a torque strap still limits how far the engine can move.

What clamps should I use? T-bolt clamps on each straight end.

How to Choose

Measure the outside diameter of the pipes you are joining and choose a coupler with a matching inside diameter. Straight couplers join two pipes in line, elbows turn the path, hump hoses absorb engine movement and reducers join two different sizes. Reinforced silicone holds its shape under boost and heat where rubber hose would balloon or crack.

More Questions

What clamps should I use with silicone couplers?

T-bolt clamps give the most even clamping force and are the best choice on boosted joints. Bead the pipe ends so the coupler cannot blow off.

Can silicone couplers be used on coolant lines?

Silicone works well with coolant, but check the inside diameter and temperature needs for your application.
