Earls Ultra-Flex™ Crimp Style Hose End. Ultra-Flex hose ends have been developed by Earl's to be used with our Ultra-Flex 650™ hose. The crimp design offers our lightest alternative in plumbing a race engine. The advantages of the smooth bore PTFE hose no longer ends at the hose end, but continues through the entire assembly!. Note: The aluminum crimp collar no longer comes with this hose end (it is available separately).
