304 Stainless Steel Brushed Elbows have become popular among some vehicle fabricators because of their beautiful brushed finish and the fact that they require virtually no preparation for welding. The 90 degree and 45 degree tight radius (1D) elbows also feature very short leg lengths, resulting in less waste. All Vibrant Performance brushed elbows are offered in sizes ranging from 1-1/2 in. to 4 in. O.D.
