45 Degree Elbows

A 45 degree silicone elbow makes a gentle turn in a charge pipe or intake without a welded bend. This collection covers the Vibrant Performance 45 degree silicone elbows in inside diameters from around 3 to 5 inches, in black and blue.

When to use a silicone elbow

Silicone elbows are useful where a pipe needs to change direction close to a component, such as at a turbo inlet, a throttle body or an intercooler tank, or where the engine moves relative to the chassis.

Leg length

Each listing gives the leg length. Longer legs give more clamping surface and can absorb a little misalignment. Allow at least an inch of engagement per side.

Common questions

Are these reinforced for boost? Yes. They are multi-ply reinforced silicone.

What clamps should I use? T-bolt clamps on boosted joints.

Can I trim the legs? Yes. Trim with a sharp blade for a square edge.

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.
