Product Details

The Earl's Performance AT593204ERL is a 3/8" NPT internal pipe plug designed for professional plumbing and custom fluid system applications. Constructed from high-grade aluminum with a hard anodized coating that penetrates the base material, this plug delivers superior wear resistance and corrosion protection compared to standard anodized fittings.

Key Features:

  • 3/8" NPT (National Pipe Thread) internal thread size for secure sealing
  • Hard anodized aluminum finish provides twice the durability of traditional anodizing
  • Corrosion-resistant coating penetrates aluminum for long-lasting performance
  • Aggressive styling complements high-performance fluid systems
  • Manufactured in the USA to Earl's exacting quality standards
  • Ideal for fuel systems, oil lines, coolant systems, and custom plumbing applications

Earl's hard anodized fittings are engineered for demanding automotive, racing, and marine environments where reliability and appearance matter. The internal plug design allows for clean, professional closure of unused ports in manifolds, blocks, and fluid system components.

Very quick and easy. Thank you

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..

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 !
