Hose End by Fragola Performance Systems. Fragola' s Race-Rite Reusable P.T.F.E. Hose Ends offer a black hard coat finish and help to eliminate fuel permeation issues common with other aftermarket hose when used with our Race-Rite or Race-Rite Pro Series Hose. Hose ends feature larger I.D. for higher flow rates and incorporate a “double-swivel” design that allows for clocking during installation.
