3/4 A.B. BRASS INSERT

Description & Features

Designed for use with nylon tubing in air brake systems, this 3/4 A.B. Brass Insert from Aeroquip is built to meet both SAE and DOT FMVSS 571.106 compliance standards, supporting operating pressures that exceed baseline SAE requirements. The brass construction provides reliable durability in demanding fluid connector applications, while the Dura-Kote plating adds a meaningful layer of corrosion resistance for extended service life in harsh environments.

Rated for a minimum working temperature of -40°F, this insert is suited for air brake and pneumatic line assemblies where cold-weather performance is a factor. Available as part of a broad range of compatible styles, it offers flexibility when specifying connectors across varied system configurations. The 3/4-inch end size accommodates standard nylon tubing connections, and the item is supplied individually.
