Product Details

The Russell Performance 640321 is an Endura plated steel AN brake adapter fitting designed for high-performance braking systems requiring superior corrosion protection. The proprietary Endura plating process creates an ultrabrite finish that delivers both exceptional durability and a premium appearance comparable to stainless steel at a more economical price point.

Key Features:

  • Endura plated steel construction provides enhanced corrosion resistance for demanding operating conditions
  • Ultrabrite finish delivers a stainless steel appearance without the premium cost
  • Precision-engineered AN (Army-Navy) thread design ensures reliable, leak-free connections
  • Ideal for brake line conversions and custom brake system installations
  • Compatible with Russell braided stainless steel brake lines and other AN-compatible brake components

This brake adapter fitting is part of Russell's comprehensive line of AN fittings available in both -3 and -4 sizes with metric or SAE thread configurations to accommodate most popular automotive, motorcycle, and racing applications. The Endura plating ensures long-lasting performance in harsh environments while maintaining a professional, high-end appearance.

Did an extensive search on line to find the best price available, and autoplicity was definitely the best. Now I no longer need to spend more time searching, I will go straight to autoplicity!

My second time ordering from Autoplicity. I price shop online and Autoplicity had the lowest price both times. Fast ship with email notifications. Autoplicity will now be my "First" site I go to for my auto accessories. Great job Autoplicity.

Very happy with the speed of shipping and with the reasonable price of the product.

Great prices for the parts I needed to replace on my SUV, a bit hard to reach customer service when I had a question about the order. When I finally did reach CS, question was answered without any issues, shipping costs seem a bit high.

Excellent experience. I like that they support Paypal.

Great prices and very quick shipping! Thanks
