Product Details

The Earl's Performance AT993303ERL is a 3/8" NPT hex head plug designed for reliable sealing in high-performance plumbing applications. This premium fitting features a hard anodized aluminum finish that penetrates deep into the base metal, delivering superior wear and corrosion resistance that lasts twice as long as traditional anodized fittings.

Key Features:

  • 3/8" NPT thread size for standard plumbing connections
  • Hard anodized aluminum coating for enhanced durability and corrosion protection
  • Hex head design allows for easy installation and removal with standard wrenches
  • Aggressive, professional appearance ideal for custom builds and visible installations
  • Made in the USA with precision manufacturing standards
  • Suitable for fuel, oil, coolant, and other automotive fluid systems

This versatile hex plug is perfect for blocking off unused ports in fuel systems, oil pans, intake manifolds, and custom plumbing setups. The hard anodized finish not only provides exceptional protection against the elements but also gives your build a distinctive, race-inspired look that sets Earl's Performance products apart.

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 so far

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 !
