Race-Rite Hose End by Fragola Performance Systems. Fragola' s New Race-Rite, Crimp-on Hose Ends have a Hard Coat Black finish. They feature an enlarged I.D. for improved flow rates and utilize a unique thread-on collar. The collar threads onto the Hose End Body and ensures a concentric crimp every time. And because they are a “Double-Swivel” design, there is no need to worry about clocking them into the proper orientation before crimping.
