Blue Anodized Aluminum Adapter (AN 826), -04 Male JIC 37 deg Flare & 1/8 Inch Male NPT Run To -04 Male JIC 37 deg Flare Branch, Tee

For brake lines, you'll want to verify that the fluid compatibility is correct. There's a link in the product details to a PDF that covers approved fluids for Aeroquip fittings.

For adding a 1/8 inch male NPT port while keeping -04 JIC 37 degree flare connections on the run and the branch, this AN 826 tee matches that setup. The run is -04 male JIC flare, the branch is -04 male JIC flare, and the extra port is 1/8 inch male NPT.

That's what this fitting is built for. The run goes -04 Male JIC on both ends, and the branch comes off at 1/8 inch Male NPT. So you keep your -04 JIC line flowing straight through and tap a smaller NPT line off the side. Aluminum body with a blue anodized finish, and it follows the Aeroquip AN 826 standard, so fitment is consistent with other AN-spec components.
