Product Details

The Russell Performance 670370 is a flare to metric adapter fitting designed to provide reliable connections in high-performance fuel systems. This precision-machined adapter allows you to convert standard AN flare connections to metric threads, making it ideal for custom fuel system builds and retrofits where metric components need to integrate with AN-style plumbing.

Key Features:

  • Precision CNC machined for exact thread engagement and proper fitment
  • Lightweight aluminum construction reduces overall system weight
  • 37-degree flare sealing angle ensures positive seal at maximum operating pressures
  • Compatible with all Russell Performance hose ends and fittings
  • Available in multiple anodized finishes including blue, black, and Endura for corrosion resistance and custom appearance
  • Designed for use in fuel, oil, and coolant applications

Russell Performance adapter fittings are engineered to meet the demands of racing and high-performance street applications where reliability and leak-free connections are critical. The anodized finish provides excellent corrosion resistance while maintaining a professional appearance in your engine bay or under-vehicle installation.

Good Price Nice Radio

This was my first order through autoplicity but I doubt it's my last. They had the best price by far on the K & N air filter I was looking for. The price was right, the filter was packed well, and the shipping was fast. No hassle transaction. Great job autoplicity!

Really good prices and fast delivery.

Really great prices with cheap shipping, best I could find. Can't wait to use the bed extender for hauling my kayaks!

Great products and great prices! Highly recommend!

Very fast shipping and appreciate email confirmations notifying me of shipment updates.
