Designed for air brake systems, this brass straight adapter connects a 1/4 in. UNF female thread to a 1/2 in. hose or tube female end, making it a reliable choice for nylon tubing connections in commercial and industrial vehicle brake circuits. The Danfoss / Eaton Brass Adapter is rated for use in temperatures as low as -40°F, though it is not recommended for environments where temperatures exceed +200°F or where battery acid may contact the tubing.
Manufactured in brass and finished with Dura-Kote plating for corrosion resistance, this adapter meets and exceeds SAE pressure standards. The Aeroquip-branded fitting is part of an extensive line of straight adapter styles, giving system designers broad flexibility when specifying connection configurations.

What size is this fitting, exactly? I'm having a heck of a time matching it up.

This adapter connects a 1/4 in. UNF female thread to a 1/2 in. hose or tube female end. The .5313 is a more precise measurement of the 1/2 inch end.
