36in Straight Hose Couplers

A 36 inch silicone coupler is three feet of reinforced hose you can cut into as many custom couplers as a build needs, or use for a long flexible run. This collection covers the Vibrant Performance 36 inch straight hose couplers in inside diameters such as 3.5 and 4 inch.

Tip

Cut with a sharp blade while rotating the hose for a clean, square edge.

Good for coolant? Yes. Silicone handles coolant well but not oil or fuel.

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.

Common 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.
