This is the only garden hose with a unique double helix construction that will not kink. Made from pliable, ultra-lightweight polypropylene with intertwining helices that increase its strength and helps maintain its shape, this hose is easier to handle than cumbersome ones constructed from thick, heavy rubber. The high-quality, internally expanded brass fittings maintain full flow even when tangled around patio furniture or pinned under a bike. The 5/8"-diam. hose will not burst or split in pressure surges up to 300 PSI—more than 3X typical home water pressure—and its crush-proof brass fittings ensure a firm connection with spigots and accessories. The weather-resistant hose remains flexible in temperatures from -20° F to 158° F.
