90 Degree Elbows

A 90 degree silicone elbow turns a charge pipe or intake a full right angle without a welded bend, which is often the only way to fit piping close to a turbo, throttle body or intercooler tank. This collection covers the Vibrant Performance 90 degree silicone elbows in inside diameters from about 2 to 4 inches, in black and blue.

Why use a silicone 90

Silicone elbows absorb engine movement and small misalignment that a rigid bend cannot. They also let you service components without cutting welds, since the joint simply unclamps.

Leg length

Each listing gives the leg length. Make sure each leg slides at least an inch over the pipe so the clamp has room to seal, and trim with a sharp blade if a leg is too long.

Common questions

Will a 90 degree elbow collapse under boost? No. These are multi-ply reinforced to hold their shape under boost and heat.

What size should I order? Match the inside diameter to the outside diameter of the pipe.

Can I use them for coolant? Yes. Silicone handles coolant well. It is not for 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.

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.
