source for LA silicone bypass hoses

The blue hose are one off, hoses. They were called blue peroxide and had a nomax knit cord in them. The standard black hose had or has a rayon cord in them. These blue hose were better than the black but supposedly not as good as the silicone hose. I always liked these darker blue over the light blue silicone hose. I had a few of these blue hose specially made before they moved hose production to Mexico. I figured I would throw a few people for a loop on this one.
