Our J bends come with a 6” & a 12” leg. For most header builds, this extra leg length mean you won’t need to buy any straight tubing. What makes our stainless mandrel bends truly a unique product? We start off with an American made 304 stainless raw material, that is then bent in the U.S. for a genuine 304 .065 stainless bend. Our material forms better, welds better and last because it is a genuine 304 stainless. 4 Into 1 Collectors - From there we supply a pair of precision formed 4 into 1 collectors. Just like our stainless bends, we start off with an American made 304 stainless and fabricate the industries finest collectors. Collector stars – A simple part that really helps speed up the fab process. Used as a weld in block off between the 4 tubes before welding the collector on, there are precision laser cut for a perfect fit between your specific primary tubes. Purge Caps – This simple, but effective method for back purging caps works great. Each kit includes 4 primary caps and one collector cap.
