Product Details

The Earl's Performance 9919BFFERL is a precision-engineered straight male adapter fitting designed to connect AN -4 (7/16"-20) female fittings to 12mm x 1.25 metric male threads. This versatile adapter is essential for custom plumbing applications where American AN fittings need to interface with metric components commonly found in import vehicles and racing applications.

Key Features:

  • Constructed from lightweight 6061-T6 aluminum alloy for excellent strength-to-weight ratio
  • AN -4 male fitting on one end with 12mm x 1.25 metric threads on the other
  • Bare aluminum finish that can be polished or anodized to match your setup
  • Precision CNC-machined for consistent thread quality and leak-free sealing
  • Made in the USA with strict quality control standards
  • Ideal for brake lines, fuel systems, oil coolers, and other fluid transfer applications

Earl's Performance adapter fittings are trusted by professional racers and enthusiasts worldwide for their reliability and precise tolerances. This straight configuration provides a clean, space-efficient connection point when adapting between AN and metric plumbing systems.

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.

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..

Everything went seamlessly. I placed my order on a Thursday and it got here Tuesday morning. No problems, and it was the best price I could find.

Glad you carried these items

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 !
