Ultra-Flex™ Hose Ends - For use with Ultra-Flex Hose

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 Mil Spec Type III hard anodizing also is impregnated with Teflon® to significantly reduce friction of the fluids running through the line assemblies. The advantages of the smooth bore teflon hose no longer ends at the hose end, but continues through the entire assembly!

All Ultra-Flex hose ends are crimped to Ultra-Flex 650™ Hose with Earl's lightweight aircraft aluminium crimp collars. These are supplied with each fitting.

Manufactured to be used with Earl's new Ultra-Flex 650™ hose, Earl's QD hose ends are made to reduce time, space and weight issues in certain race situations. These hose ends are threadless and the male and female designs are manufactured for smooth and effortless installations every time. They are coupled by a threadless clamshell colsure that is manufactured by the leader in the industry - Adel Wiggins. Earl's QD hose ends are plated with the same Mil-Spec III hard anodizing and our exclusive Teflon© impregnation for a great reduction in the fluid flow friction. Our male ends also come with plasma coated nitrile o-rings installed for longer life.

ULTRA-FLEX™ AN MALE HOSE ENDS

Ultra–Flex Male AN Hose ends have been developed by Earl's to be used with our Ultra–Flex 650™ hose. These hose ends eliminate the need for an Adapter so they provide a lower profile where space is limited. The male AN thread swivels for easy installation and seals on a Buna O–ring. The traditional hex sizes have also been reduced to save weight and the port side is contoured for increased flow. (Teflon® is a registered trademark of DuPont Performance Elastomers)
