Product Details

The Firestone 3121 Male Branch Tee Air Fitting is a precision-engineered pneumatic fitting designed for use with Firestone air spring and air ride suspension systems. This male branch tee allows a single air line to be split into two separate lines, enabling dual air bags or accessories to be controlled from a single air source or port.

Key Features:

  • Male branch tee configuration for splitting a single air line into two outputs
  • Compatible with Firestone Ride-Rite and WorkHorse air spring systems
  • Durable brass or nickel-plated construction for corrosion resistance and long service life
  • Designed for use with standard 1/4" NPT air line fittings common in air suspension applications
  • Ensures a leak-free, secure connection in pressurized air systems
  • Compact design for easy installation in tight spaces

The Firestone 3121 is an ideal solution when routing air lines to multiple air springs or when adding additional air accessories such as gauges or inflation valves to an existing system. It is a genuine Firestone replacement and upgrade fitting, built to meet the same standards as original equipment components.

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!
