Fragola -4AN Tube Sleeve - Steel

When you're putting together a fuel system or any other fluid line using AN fittings, you'll need to make sure your hose is properly supported. This Fragola steel tube sleeve is designed to slide inside your -4AN hose, giving it a solid foundation to prevent it from collapsing when you tighten down your fitting. It's a small part, but it makes a big difference in ensuring a leak-free and reliable connection for your fuel, oil, or coolant lines.

Made from steel, this sleeve is built to handle the pressures and vibrations found in an engine bay. It's a straightforward component that does its job by reinforcing the hose wall right where the fitting seals. Using a tube sleeve like this is a common practice when working with braided hoses to ensure they don't get pinched or deformed, which could lead to a failure down the road.
