1.5" (38mm) Aluminum Radiator Hose Filler Neck – 45-Degree Inline With Cap

Building a custom cooling system or need to relocate your radiator cap?

This aluminum filler neck is just the ticket.

It's a 45-degree inline neck, meaning it splices right into your top radiator hose.

The hose connection size is 1.5 inches or 38mm.

It's made from aluminum with a clean silver finish, and the best part—it's 100% leak tested, so you know it's solid right out of the box.

It comes complete with a cap, so you're ready to install.

It's a universal fit part, so it'll work on a bunch of custom projects, hot rods, or off-road rigs.
