I'm doing some minor fuel re-plumbing in my engine compartment. I picked up a few quarter inch bronze fittings at WM, however they had no pipe nipples. After checking a few stores the best I could find is "red brass" 1/4 inch nipples. Should I use the two metals together? If you search the WM website for bronze nipples is give the response below. I'm using it in a dry location. I don't really have room to put rubber hose between each fitting. Should I just get red brass for the whole job despite less strength and corrosion resistance?


From the WM website...

We cannot source bronze nipples, and so we offer brass instead. Due to the difference in nobility between brass and bronze, we recommend that you not use them together in saltwater environments. We suggest the use of tailpieces and hose instead.

IIRC, red brass is better than yellow brass. Mixing brass and bronze is generally a bad idea. :)

Steve,

Don't waste your money! Your using this for the FUEL system and this is NOT below waterline and subject to galvanic corrosion (if it is you have other issues). Any brass whether yellow, red, what ever, will be fine for a fuel system.

You should always a UL marine rated bronze for below water fittings and not brass. Interior domestic water (fresh water system for drinking) and fuel systems do not require or need bronze or even red brass. The brass fittings at HD will do just fine.

You should however use non-perforated hose clamps like those from AWAB and USCG certified fuel hose.. Using brass or copper based alloys in an aluminum fuel tank is generally frowned upon and is not in-line with ABYC standards.

Thank you for the replies. I think I'll use the red brass for now but keep an eye out for a bronze nipple. Since red brass has some tin in it I think the dissimilar metal issue can't be too dramatic.

They list bronze for most fittings, but red brass for nipples. I'm starting to thing no one makes bronze nipples.

Thanks for the info. Brass it is.

I guess I was making an issue over nothing. I was just trying to get it right.

Re: Steve

The Groco PN series bronze nipples are available, but I wouldn't think it's needed here too.
Yep and I discovered them a few years ago. They are a nice machined bronze nipple with wrench flats... It a lot of work to cast then machine pipe nipples but Groco is doing it...
