Fragola -4AN Tube Sleeve 10 Pack

When you're working on fuel lines, oil lines, or any other fluid transfer system that uses AN fittings, a tube sleeve is a small but important part. This 10-pack of Fragola -4AN tube sleeves is designed to reinforce the end of your tubing, creating a solid base for your fitting to seal against. They help prevent the tubing from collapsing or deforming when you tighten down the AN fitting, which is crucial for preventing leaks.

These sleeves are made from a durable material that's meant to hold up in engine bay environments. The -4AN size means they're intended for tubing with a 4AN outer diameter, a common size for many performance and custom applications. Having a few extra sleeves on hand is always a good idea, as they can sometimes get lost or damaged during installation.
