Product Details

The Earl's Performance 981666ERL is a straight male adapter fitting that converts AN -6 (9/16"-18 thread) to 3/8" NPT (National Pipe Thread). Precision-machined from 6061-T6 aluminum alloy, this lightweight adapter provides a reliable connection between AN hose ends and NPT-threaded components in fuel, oil, and fluid transfer systems.

Key Features:

  • AN -6 male (9/16"-18) to 3/8" NPT male thread configuration
  • CNC-machined from 6061-T6 aluminum for strength and light weight
  • Bare aluminum finish for custom anodizing or use as-is
  • Straight inline design for direct connections
  • Made in the USA with precision tolerances
  • Ideal for racing, performance automotive, and custom plumbing applications

This adapter is part of Earl's extensive line of AN and NPT fittings, designed to meet the demanding requirements of motorsports and high-performance applications. The male-to-male configuration allows you to connect AN -6 hose ends to components with 3/8" NPT female ports, commonly found in fuel pressure regulators, oil coolers, turbochargers, and various engine accessories.

Wow!! I came across Autoplicity while searching for a fuel pump for my Trans-Am. Not only did they have the cheapest price for the part, but they also had extremely reasonable shipping cost. Most websites claim to have free shipping but it seemed the cost of shipping was added to the cost of their part. Then I find out my order was processed and shipped within one business day!! I'll definately be bookmarking Autoplicity's home page!! Thanks!!

Bought some wire looms for my Chevy from them. Great price, service, and shipping speed!

The item arrived fast and in good condition. There however seems to be a glitch with the scale the first time we weighed something. After we shut it off and then back on it seemed to be OK.

I ordered a Grant 1103 Steering Wheel, Order Number: 16767. Great prices, quick shipping, good customer service, an all around deal. Thank you.

The part I purchased had the lowest price I could find online anywhere.. Simple transaction and fast shipping.. Ordered on a Monday and delivered by Friday..

Easy and quick payment methods!

It has been a smooth and easy process. I would definitely use them again.

Great Prices and Very Fast Shipping. Will order again in the future. Customer Service was great when I called about a question with my order.

Great prices and fast delivery.

best prices around !! Shipping was FAST !
