Mandrel and Nosepiece Kit 3/8-16

The Mandrel and Nosepiece Kit 3/8-16 is an essential tool for fabricators, custom builders, and automotive technicians working with exhaust systems, fuel lines, and brake applications. This ALLSTAR PERFORMANCE kit addresses a critical need in vehicle modification: creating precision bends and securing connections where standard off-the-shelf components won't fit or perform reliably. Whether you're adapting a turbo manifold, routing custom fuel rails on an engine swap, or installing braided stainless steel lines, this kit ensures professional-grade results without the cost of specialty fabrication shops.

The 3/8-16 thread specification indicates compatibility with standard 3/8-inch diameter tubing and fittings using 16 threads per inch—a metric common in automotive hydraulic and pneumatic systems. The mandrel component allows precise, repeatable bends without kinking or flattening tubing, maintaining flow integrity and structural strength in high-vibration engine bays. The nosepiece secures the tube during the bending process, preventing slippage and ensuring concentricity. Together, these precision-machined components deliver the control necessary for fabricating clean bends at multiple angles, critical when space is limited or OEM routing won't accommodate your build.

This kit benefits engine builders, hot rod enthusiasts, and professional mechanics tackling engine conversions, custom fuel system installations, and brake line upgrades. The compact design—weighing just 0.12 lbs and measuring 4 x 0.7 x 7.05 inches—makes it portable for both shop and trackside use. ALLSTAR PERFORMANCE's reputation for precision tooling ensures repeatability across multiple bends, eliminating guesswork and rework. Compatible with standard tube benders and brake line bending equipment, this mandrel and nosepiece kit pays for itself after just two or three custom fabrication jobs that would otherwise require outsourcing.
