Shop Fabrication Parts & Materials at Black Ops Auto Works for stainless steel tubing, titanium tubing, aluminum charge piping, mandrel bends, V-band clamps, flanges, merge collectors, AN fittings, PTFE hose kits, braided fuel and oil lines, heat shields, welding supplies, brackets, bungs, and hardware for building custom exhaust systems, turbo plumbing, intercooler piping, fuel systems, and engine bay routing. Start with tubing (304 or 321 stainless, titanium, or aluminum) in the right diameter and wall thickness, then add mandrel bends, flanges, V-bands, and clamps to complete the joint work. AN plumbing follows the same pattern: match dash size to horsepower target, pair the right hose (PTFE or CPE) with matching hose ends, and use adapters, bulkheads, and distribution blocks to route fuel, oil, and coolant cleanly. Shop by material (stainless, titanium, aluminum), fitting type (AN, ORB, NPT), diameter, or brand (Vibrant, Ticon, Stainless Bros, Radium, Fragola, DEI, ATP). ...

Fittings
Automotive fluid system fittings are the hardware that connects hoses, hard lines, and components within fuel, oil, cooling, brake, power steering, and intercooler circuits, and the quality and correct sizing of these fittings directly determines whether a high-performance fluid system remains leak-free under the pressure, temperature, and vibration conditions that race and street performance environments produce. The AN fitting standard, derived from military Aircraft-Navy specifications, provides a consistent thread and flare geometry across fuel, oil, and hydraulic applications that allows interchangeability between brands and simplifies system design by providing a known thread engagement and sealing approach for every connection. Swivel fittings, bulkhead adapters, 45-degree and 90-degree elbow fittings, tee and union adapters, and reducer fittings allow performance builders to route lines through tight spaces and around obstacles while maintaining correct flow area without res...
