What is the thread size for the 9/16in-18 end?

The fitting has a 9/16in-18 male thread. This end is designed to thread into a component that has a matching 9/16in-18 female port, often found on fuel rails, oil filter housings, or other engine components.

Does this fitting require thread sealant?

No, this fitting is designed with an O-ring seal on the 9/16in-18 end. The O-ring creates a positive seal against the mating surface, so thread sealant is typically not needed or recommended.

What is the purpose of the -6AN fitting?

The -6AN end is a standardized fitting for automotive fluid transfer lines. It allows you to connect a hose with a -6AN fitting to this adapter, enabling custom plumbing for fuel, oil, or other fluid systems.

About this part

Product Details

This straight male fitting from Fleece Performance uses a 9/16in-18 thread on one end and a -6AN fitting on the other, making it useful for custom fuel or oil line setups. The O-ring seal ensures a tight, leak-free connection where it threads into a component with a 9/16in-18 port. Its black finish offers a clean look for your fabrication project.

Built for custom plumbing needs, this fitting is a solid choice when you need to adapt a standard -6AN hose end to a component that uses a 9/16in-18 female thread. The O-ring is crucial for creating a reliable seal without needing thread sealant, which is common practice for AN fittings. This makes for a cleaner installation and easier disassembly if needed down the road.
