Zinc-plated steel compression-style hose end that adapts 3/8 inch OD tubing to a reusable -6 AN Teflon hose connection. Made in the USA, the assembly includes the -6 AN hose end body with brass olive and nut, along with a compression sleeve and compression nut for securing to stainless or mild-steel hard line. Commonly used in fuel systems, transmission coolers, and power-steering return circuits where a 3/8 inch tube needs to transition to -6 AN hose. Requires approximately one inch of straight tubing for proper installation.
