Straight Hose Couplers

A short straight coupler joins two pipes of the same diameter with a minimal gap. This collection covers the Vibrant Performance straight silicone hose couplers in common inside diameters such as 3.125 inch, in short lengths around 3 inches.

Tip

Leave at least an inch of engagement on each pipe and use T-bolt clamps on boosted joints.

Reinforced? Yes, multi-ply reinforced for boost and heat.

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.
