DEI Heat Shroud Line Sleeving: 20, 16 and 12 AN Sizes

Beat the Heat

Design Engineering Inc.’s (DEI) AN-sized Heat Shroud Sleeves for 20, 16 and 12 AN sizes are an ideal way to reduce heat strain and abrasions on lines, hoses and wires, damage that could result in failure of all three of these components.


Sized perfectly for AN sizes and featuring an easy wraparound install, DEI’s Heat Shroud Sleeves are constructed from a high-temperature rated, glass-fiber fabric with an insulating inner layer and a heat-reflective outer surface.

The added convenience of a hook and loop closure design along the edge makes installation easy. There’s no need to remove one end of the hose, just wrap Heat Shroud Sleeve around the hose and close the hook and loop edge. It’s that simple.

In addition, the AN-sized Heat Shroud Sleeves are lightweight for high-performance applications. They are also pliable, so they can be used on tight bends, and there’s no need to disconnect lines to install them. It also prevents fluids from potential vapor lock. The Heat Shroud protects against oil, dirt, road grime and is fireproof.
