Buying Guide

37-degree flare fittings make strong connections for many jobs. They stop leaks in tubes and hoses. Pick the right one for your needs.

Real users love how these fittings stop leaks fast and last long. One person said the FITOK stainless steel set works great for high pressure, with no worries about rust. Another shared the ANCIMOON kit made installing brakes easy and clean.

  • Material: Choose stainless steel for rust-proof use in wet areas. Carbon steel is fine for dry jobs but needs protective coating. Pick based on your environment.
  • Size: Match the fitting size to your tube or hose diameter. Common sizes include 1/4 inch, 1/2 inch, and 3/4 inch. Check if it fits your setup.
  • Pressure Rating: Look for ratings up to 5000 PSI for tough jobs. Lower ratings work for basic tasks like home repairs. Make sure it matches your system’s needs.
  • Type of Fitting: Decide between nuts, sleeves, adapters, or tools. Nuts and sleeves join tubes directly. Adapters connect different styles. Tools flare tubes for a tight seal.
  • Standards: Pick ones that meet SAE J514 for quality. These ensure safe and reliable performance. Brands like FITOK and Eaton follow them.
  • Durability: Fittings with hardened parts last longer. Zinc plating helps prevent rust. Think about heat and cold in your use.
  • Compatibility: Ensure the fitting works with your system. JIC 37-degree style fits AN and hydraulic hoses. Test for a snug join before full use.
