rotate a material in the Material Graph

I don’t know how to rotate a material I am making in the Material Graph.
The whole thing is procedural. I’ve tried using Sine but I can’t figure how to get it to rotate the Material 90 degrees.

You can use the Custom Rotator node as an Input on UV Channel on the Linear Gradient node and in between the TexCoord and Multiply node.

If you want continues rotation, you can use the Rotator node instead.

I did find a solution that is easier then using the Custom Rotator:
Rotating Texture 90 degrees - #7 by Razivoid.
