Female 3/8-24 Inverted Flare to Male 1/8 NPT Tube Nut

This special adapter fitting lets you connect your 3/16" brake tubing to a 1/8 NPT female port. It is designed for installing a proportioning valve or line lock in an existing hard line, but it is also great for connecting a hard brake line to an aftermarket caliper with 1/8 NPT threads (such as Wilwood).

The male end of this adapter has 1/8 NPT male tapered pipe threads to fit a standard 1/8 NPT port. The female end accepts a standard 3/8-24 inverted flare tube nut (not included). To install, just apply a thread sealant (sold separately) to the NPT threads and screw the fitting into your port. Then screw your tube nut into the adapter. High-pressure brass. Sold individually.

If you only have the unflared tubing with no tube nut, we also offer a 2-piece 3/16 Brake Line to 1/8 NPT Adapter Kit (Part No. AF375-02), which includes a similar adapter plus a 3/8-24 tube nut.
