Buying Guide

Upgrading your ride? AN fittings are your best bet for secure, high-performance connections. They turn complex systems into smooth, leak-free setups that work under pressure.

  • Material Quality: Look for 6061-T6 aluminum or 304 steel. These materials offer strength without extra weight and resist corrosion and wear.
  • Pressure & Temperature Ratings: Check for high PSI ratings (1,500–2,250) and wide temperature ranges (–40°F to 250°F). These ensure reliability in extreme conditions.
  • Compatibility: Choose fittings that match your hose type (CPE, nylon braided, rubber) and thread sizes (like 9/16-18UNF). Adapters help connect AN to NPT threads.
  • Ease of Installation: Swivel fittings and push-lock designs simplify tight-space setups. Kits with separator clamps or adjustable wrenches save time and reduce clutter.
  • Versatility: Opt for multiple angles (45°, 90°, 180°) and universal use (fuel, coolant, power steering). This covers diverse system needs in one buy.
  • Reusability: Fittings labeled reusable and recyclable cut long-term costs and waste. They’re ideal for frequent upgrades or repairs.
  • Size & Fit: Ensure the wrench or fitting matches your AN size range (e.g., 3AN–16AN). A proper fit avoids leaks and system failures.
