This is a mandrel for installing the fittings on Aero Quip or similar flexible hoses such as fuel and oil lines. It is for hoses with a 1/4 inch Inside Diameter. I used it to make the fuel lines and oil cooler lines for my Long Ez. The pictures show the type of fittings that it is used with.
Price is $13 and includes CONUS shipping.
