Description
Our 4 inch short 45° butt-weld elbow is a sanitary, 316L stainless steel elbow designed for high-purity connections in the food processing, brewing, industrial, and pharmaceutical industries.
It is designed without tangents meaning both ends are shorter, allowing for tighter turns. Butt welding creates a strong, seamless connection by fusing separate sanitary tubing onto each end of the elbow.
Butt-weld 45 degree elbows are sometimes referred to as weld 45 degree elbows.

304 vs. 316L Stainless Steel
304 and 316L stainless steels appear visually identical, but have distinct performance characteristics.
304 stainless steel contains approximately 18% chromium and 8% nickel, making it suitable for kitchen applications and indoor environments. It performs well under normal conditions but becomes vulnerable to corrosion when exposed to salt or harsh chemicals. This makes it the more economical option for standard uses where corrosion resistance is not a primary concern.
316L stainless steel contains 2-3% molybdenum in addition to chromium and nickel, providing superior corrosion resistance, especially against saltwater and chemicals. Furthermore, 316L has a lower carbon content than 316, increasing corrosion resistance and making it ideal for welding. While it commands a higher price point than 304, it is recommended for outdoor marine environments and food processing applications involving salt.
304 is useful for some standard applications, but for the highest level of durability and harsh environments or saltwater exposure, the additional investment in 316L stainless steel is justified for long-term success.
