AC PERFORMANCE 12AN AN12 Straight Black Aluminum Fuel Cell Bulkhead Adapter Fitting -12 AN Locking Nut With Oil-resistant Washer

Very good product, expensive but worked very well

Great parts!!

Works well, the teflon washers are water tight.

Works like a bulk head should only one side has threads so its good for a fuel return in a tank hopefully the washers hold up to e85

I like the product it was of good quality. I used it on a Engine bill.

These work well for my valve covers to set up a breather systems

Fit good no leaks

It works perfect. Used as a breather fitting for valve cover.

worked perfect for me

Good quality nothing to complain about
