What is the purpose of a bulkhead fitting?

A bulkhead fitting is designed to pass through a panel, like a firewall or fuel tank, creating a sealed connection point. One side connects to a hose or line, while the other side connects to a component or another fitting on the opposite side of the panel.

What does the -20AN size refer to?

The -20AN designation refers to the size of the male flare fitting. In the AN (Army-Navy) standard, the number indicates the diameter in sixteenths of an inch, so -20AN corresponds to a fitting with a 20/16ths (or 1.25 inch) outside diameter.

Does this fitting come with the bulkhead nut?

No, the bulkhead nut is sold separately. You will need to purchase the appropriate size bulkhead nut to properly install this fitting through a panel.

About this part

Product Details

This straight bulkhead adapter from Vibrant Performance uses a -20AN flare on one end and connects to an NPT thread on the other, designed to pass through a panel or firewall. It's constructed from 6061 aluminum alloy, which keeps the fitting lightweight while still offering solid reliability for fuel or oil systems.

The anodized black finish not only looks good but also helps protect the aluminum. This adapter is made to provide a smooth flow path and an anti-leak seal, making assembly straightforward. It’s a popular choice for connecting components like oil pumps, fuel pumps, and fuel filters through bulkheads.

Keep in mind that the bulkhead nut is sold separately, so you'll need to account for that when ordering.
