90 Degree Reducer Elbows

A 90 degree reducer elbow turns a corner and changes pipe size in one silicone part. This collection covers the Vibrant Performance 90 degree reducer elbows, many stepping from 4 inch down to 3 or 2.5 inch, mostly in black.

Common uses

They are a natural fit on a turbo compressor inlet fed by a large intake pipe, at an intercooler tank whose outlet differs from the charge pipe, or at a throttle body that is smaller than the pipe feeding it.

Sizing

Each elbow lists both inside diameters and the leg lengths. Match each end to the outside diameter of the pipe it slides over, and allow at least an inch of engagement.

Common questions

Does reducing in a bend hurt flow? A smooth silicone reducer elbow flows well and avoids the sharp step of separate parts.

Can I trim a leg? Yes, with a sharp blade for a square cut.

What clamps should I use? T-bolt clamps sized for each 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.
