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!
