Product Details

The Firestone 3104 is a brass 1/4 inch NPT male connector designed for 3/8 inch air line applications in air suspension systems. This industrial-grade fitting provides a secure, leak-free connection between air lines and air spring components, valves, or manifolds.

Key Features:

  • Brass construction for corrosion resistance and durability
  • 1/4 inch NPT male thread for standard compatibility
  • Fits 3/8 inch OD air line tubing
  • Bulk pack of 25 fittings for fleet installations or shops
  • Suitable for air helper springs, load leveling systems, and custom air suspension setups
  • Temperature and pressure rated for automotive air suspension use

This connector is commonly used in Firestone Ride-Rite and other air spring installations where reliable air line connections are critical. The NPT threads provide a tight seal when properly installed with thread sealant or tape. Ideal for professional installers, fleet maintenance, or DIY enthusiasts working on multiple vehicles.

Not one issue at all

I ordered my K&N cold air intake order number 17133<br>From autoplicity for almost half price compared to other sites online. I will continue my purchases here n stop my searches elsewhere. And delivery time is fast!

Great service, awesome prices, incredibly fast shipping. A++ I would absolutely suggest you to my friends and family

Good so far

Quick and efficient, Thank You!

The ordering process went really smoothly. Got my ordering info e-mailed smartly and was able to track the order easily. Looking forward to using my item as soon as it gets here!

Had to upgrade to a Snell 2010 helmet this year, bought the identical helmet for $200 less than I paid 8 years ago! Fast shipping, I will be checking Autoplicity first in the future!
