This Stainless Bros mandrel bend gives fabricators a factory-precise 90 degree turn in 1.88 inch tubing with a tight 1D radius, so tight packaging jobs and header collector routing stay smooth instead of kinked. Built from 304 stainless in 16 gauge (.065 inch) wall thickness, it holds its shape through the welding process and resists work hardening better than cheaper bends on the market.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eMandrel formed for a constant, unrestricted inner diameter through the full bend\u003c\/li\u003e\n\u003cli\u003e304 stainless steel construction resists corrosion and high exhaust gas temperatures\u003c\/li\u003e\n\u003cli\u003e16 gauge (.065 inch) wall thickness for durability without excess weight\u003c\/li\u003e\n\u003cli\u003eTight 1D bend radius suited to tight engine bay and undercarriage routing\u003c\/li\u003e\n\u003cli\u003eNo leg design leaves both ends open for custom length cutting\u003c\/li\u003e\n\u003cli\u003eTIG weld ready surface finish for clean fabrication welds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eStainless Bros\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMPN\u003c\/td\u003e\n\u003ctd\u003e601-04856-3100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e601-04856-3100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003e304 Stainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e1.88 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBend Angle\u003c\/td\u003e\n\u003ctd\u003e90 Degree\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBend Radius\u003c\/td\u003e\n\u003ctd\u003e1D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWall Thickness\u003c\/td\u003e\n\u003ctd\u003e16 Gauge (.065 inch)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLeg Length\u003c\/td\u003e\n\u003ctd\u003eNo Leg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch4\u003eWhat's Included\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Stainless Bros 1.88 inch 1D 90 degree 16 gauge no leg mandrel bend\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eAbout Stainless Bros\u003c\/h4\u003e\n\u003cp\u003eStainless Bros builds mandrel bends, weld fittings, and exhaust components engineered for fabricators who need consistent wall thickness and true roundness through every bend.
