AN FITTINGS SEARCH

Why shop here for your AN fittings and stainless steel lines? Our stainless steel lines utilize a smooth bore PTFE tube inside a braided stainless steel sleeve. This combination gives you extreme pressure, heat, and chemical resistance along with a shiny and professional appearance. If you're building oil lines, fuel lines, doing an ethanol / E85 conversion, or any other fluid transfer system, www.anfittingsdirect.com is your magic bullet.

Our stainless steel line termination fittings utilize our own Triple-Grip design, which grips the PTFE tube in two places and also grips the stainless steel line itself, giving you a sturdy and leakproof installation.
Our AN fittings are compatible with other AN fittings on the market because the AN specification is well known and standard in the automotive aftermarket.
Our AN fittings and stainless steel lines come in a wide variety of colors, allowing you to build 8 different color combinations. Match your vehicles paint, or use red for lines carrying hot fluid and black for lines carrying cool fluid.
Our AN fittings and stainless steel lines are superior to the competition in every way, and they cost less too!
