The Aeroequip 303 hose and 491 fittings are assembled using this tool. It is absolutely necessary. I made hose assemblies today for the first time. Im pleasantly surprised how well and easy this was to do. Expensive...yes. but necessary.

Good tool, well built and works as it should, just very overpriced. Lost a star for high price.
