Description

Our 4 inch by 3 inch butt-weld eccentric reducer is a sanitary, stainless steel fitting engineered to provide a seamless flow between two pressurized pipes of different diameters. 

Eccentric reducers are typically used when pipes have a horizontal orientation, you need to maintain the axis of one side, or when air and liquids are flowing together.

Made from 304 stainless steel, this reducer has excellent corrosion resistance and maintains impressive long-lasting performance while reducing risks of turbulence and pressure loss.

Butt-weld eccentric reducers are sometimes called weld eccentric reducers.

Uses:
Chemical transfer
Wastewater systems
Food processing
Ventilation & ducting
Water treatment
HVAC exhaust
Gas & Oil pipelines
Fermentation
Cosmetic
And more

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.
