PERRIN Subaru / Universal Coolant Hose Adapter - 1.5in / 38mm ID Hose

This Perrin coolant hose adapter is made from a solid piece of billet aluminum, machined to accept a 1.5-inch (38mm) inner diameter hose. It's a straightforward part designed to help you route coolant lines cleanly, especially when you're adding aftermarket gauges or relocating components in your engine bay.

The adapter features a smooth, consistent bore that won't restrict coolant flow, and the O-ring seal ensures a leak-free connection. It’s a simple but effective piece for custom cooling setups, giving you a professional look and reliable function.
