Pipe Elbow Fittings Diagram - Types and Applications for Plumbing & HVAC #215170 (License: Personal Use)

This diagram displays four standard 90-degree elbow pipe fittings, differentiated by color (teal and blue) to indicate possible material or size variants. Each fitting has clearly rendered external and internal threading for secure pipe connections, and a smooth radius bend to minimize flow restriction. The clean vector style makes it ideal for technical documentation, product catalogs, or educational resources in mechanical engineering and construction trades.

Used on plumbing supply websites, HVAC design guides, or engineering education pages to illustrate basic pipe fittings. Matches user intent for identifying, comparing, or selecting elbow joints for piping systems.
