Red E stainless replacement partner solutions for Case-IH and Flexi-Coil Poly Tank Air Carts are made of high-quality, corrosion resistant 304 stainless steel with pacified welds to maintain corrosion resistance. Use of spot welding, laser cut parts and slot and tab assembly produces a consistently quality product every time. These parts replace the non-stainless steel OEM versions for a similar price, and are field-proven to maintain all of the functions of the original parts.
