Identical except for color. http://www.tridentmarine.com/stage/sanbtation.htm It's been on the market for more than 15 years without a single reported odor permeation failure.

However, I do not recommend replacing only once section of hose. If you're gonna do part of it, do it all. It's not the hose that's the worst part of the job..it's the job. So you only want to do it once...you don't want to do it over and over.

Use Shields or Trident #148 for sizes smaller than 1".
