Product Details

The NOS 17550NOS is a blue anodized aluminum tube nut designed for use with nitrous oxide systems and other high-performance fluid lines. This precision-machined fitting connects -3AN (3AN) fittings to 3/16-inch aluminum hard line tubing, providing a secure, leak-free connection in demanding racing and performance applications.

Key Features:

  • -3AN female fitting connects to 3/16-inch aluminum tubing
  • Blue anodized aluminum construction for corrosion resistance and lightweight performance
  • 37-degree AN flare design ensures proper sealing (compatible with AN fittings only)
  • Ideal for nitrous oxide lines, fuel lines, and other hard line plumbing applications
  • Precision manufactured for reliable, leak-free connections
  • Sold individually

This tube nut is engineered specifically for use with NOS nitrous systems and other applications requiring secure aluminum hard line connections. It is designed exclusively for racing use and may not be legal for street use on emissions-controlled vehicles. Always use matching 37-degree AN fittings to avoid leaks—do not mix with 45-degree SAE fittings.

Best price on a timken wheel bearing I could find. I will be doing business with them again.

Really good prices and fast delivery.

I received my Borgeson steering shaft today for my 1990 dodge 1st gen. This is where I found the lowest price for the product. I was also very pleased in the speedy delivery. I will definitely use this company again.

Autoplicity has the cheapest prices around and fast shipping. I will do business with them again in the future.

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