Technical tools built for workshops, fabricators and track day enthusiasts. Every calculator uses proven engineering formulas — not guesswork. All tools are free and run entirely in your browser.
AN Fitting Size Calculator
Identify the correct AN dash size for any line. Covers -3 to -20 with ID/OD, thread specs and typical applications.
Thread Identifier & Adapter Finder
Identify metric, NPT and BSP threads by pitch and diameter. Find the correct AN adapter for any fitting.
Fuel System Sizing Calculator
Size your fuel pump and lines for any power level. Accounts for BSFC, fuel type, efficiency and injector duty cycle.
Hose Pressure Rating Reference
Working and burst pressure ratings for SS PTFE, nylon, SS rubber, and silicone hoses across all AN sizes.
Flow Rate Calculator
Calculate volumetric and mass flow through any AN bore. Outputs L/h, GPH, cc/min and Reynolds number.
Pressure Drop Calculator
Darcy-Weisbach pressure loss through AN lines including fittings. Uses Swamee-Jain for turbulent flow.
Banjo Bolt Size Finder
Look up M10–M22 banjo bolts: torque specs, crush washer dimensions, AN compatibility and applications.
Brake Line Sizing Calculator
Master cylinder bore + caliper pistons → hydraulic ratio, line pressure, clamp force and recommended AN line.
Hose Length Estimator
Plan multi-segment hose routes, add fitting allowances, apply a routing buffer and get a final order quantity.
Oil Cooler Line Sizing
Engine displacement + power → correct AN size for oil cooler feed/return lines and recommended cooler core size.
Catch Can & Breather Line Sizing
Cylinder count, boost and track use → recommended catch can volume, AN breather size and port thread specs.
Motorsport Unit Converter
Pressure, flow, torque, power, temperature, speed, mass and length — all in one fast multi-category converter.
