The Cool-Flex all-copper fluid transfer hose helps your engine shed heat.
 

Cool-Flex is an open-pitch seamless corrugated construction. There?s no seam and nothing to unwind. That?s why Cool-Flex will never collapse, never lose its shape, and never wear out.
 

Cool-Flex hose finishes are available in show chrome, deep black, cool blue, raging red and electric purple. The end covers are available in satin aluminum, polished aluminum, deep black, cool blue, raging red, electric purple, show chrome and 24K gold.
 

Aluminum billet end covers have internal grooves to help position hose clamps. Tapered end of cover goes toward Cool-Flex.
 

100% stainless steel hose clamps won?t corrode or sieze.
 

Rubber coupling has woven yarn core so it can take the heat and pressure.
 

Extruded neoprene reducers make an accurate fit to any water neck.
