High-pressure, braid-reinforced, neon, PVC hose. 800 PSI working pressure. 3000 PSI burst. So good we warrant it for three years. Reinforced PVC with high burst strength. Melded inner core and cover to form complex reinforcement that will not separate under high pressure. Light, bright colors are easy to see; won't mark curbs or sidewalks. Sizes to fit any need. Costs you less because it lasts longer.
