Pipe Elbow Icons - U-Bend and 90° Elbow for Engineering & Plumbing Design #3900807 (License: Personal Use)

The image displays two stylized pipe elbow fittings commonly used in plumbing and mechanical engineering diagrams. The left icon represents a U-bend (180° return), while the right shows a standard 90-degree elbow with flanged ends. Both are rendered in layered grayscale with subtle shadows to suggest dimensionality and material depth, suitable for digital interfaces or schematic documentation.

This image is typically used on engineering resource sites, CAD symbol libraries, plumbing software UIs, or educational materials illustrating pipefitting components; it serves users searching for technical icons or diagram elements.
