TSI INOX Conduits presents our premium Rigid 90° Standard Stainless Steel Elbow, a critical component for professional electrical raceway systems requiring durable, corrosion-resistant directional changes. Manufactured in strict compliance with UL 6A standards and available in a comprehensive range of angles, our stainless steel rigid conduit elbows provide the strength, reliability, and sanitary finish demanded by industrial, commercial, and food-grade installations.
Whether you are routing conduit around structural obstacles, creating underground stub-ups, or interconnecting conduit runs, TSI's stainless steel elbows deliver the precision and durability your project demands.
Each elbow features precision-cut NPT (National Pipe Taper) threads on both ends, ensuring secure, leak-resistant connections with standard rigid conduit, couplings, and fittings. Threads are protected by color-coded plastic caps to preserve thread integrity during transport and storage.
Our standard radius elbows (approximately 1.5D bend radius) provide the optimal balance between smooth cable pulling and space efficiency, ensuring compliance with NEC bending radius requirements for conductor protection.
The polished stainless steel surface and passivated interior create a sanitary raceway system suitable for food processing, pharmaceutical, and cleanroom applications where bacterial growth and contamination must be minimized.
Stainless steel elbows are ideally suited for installation on conduit raceways for:

Our 304 stainless steel rigid elbows offer excellent corrosion resistance and formability for general industrial and commercial applications. The 304 alloy provides reliable performance in food processing, pharmaceutical, and manufacturing environments where resistance to atmospheric corrosion and mild chemicals is required.
For the most demanding corrosive environments, our 316 stainless steel rigid elbows deliver superior protection with molybdenum-enhanced alloy composition. The 316 grade provides exceptional resistance to chlorides, acids, and marine atmospheres, making it the preferred choice for offshore, chemical processing, and wastewater treatment facilities.
Our rigorous pickling and passivation process removes surface contaminants, welding scale, and iron particles while promoting the formation of a protective chromium oxide layer. This enhances the interior corrosion resistance, protects conductors from moisture ingress, and ensures a clean raceway for cable installation.
The exterior #4 polished finish provides a bright, easily maintainable surface that is modern, attractive, and simple to clean. This sanitary finish:
