Earls - 6An Bulkhead Adapter Ss Frame Pass Through

The Earls 6AN Bulkhead Adapter SS Frame Pass Through is a premium stainless steel fitting designed for custom applications where AN plumbing must pass through frame tubing. Ideal for street rods and race cars, this adapter eliminates the need for tabs or brackets, allowing plumbing to be hidden along the inner edge of frame rails. It fits through tubing from 1.5" to 2.0" thick and comes with a matching flanged bulkhead nut for a secure installation. Constructed from 304 stainless steel with a natural finish, it features AN flares on both ends and is suitable for use in brakes, fuel systems, transmission coolers, and other plumbing systems. The adapter measures 3.656" in length and requires a 9/16" mount hole diameter. For optimal performance, use anti-seize to prevent galling on the bulkhead nut.
