1 diameter layflat water hose, perfect for use with centrifugal and surface mounted water pumps. Lightweight layflat hose is easy to move, store and requires no real installation (other than unrolling and laying). Unobtrusive too, it lies flat to the ground when not in use but outlet water pressure is sufficient to open it up to deliver pumped water to exactly where it's required. Operating Pressure 43.5psi. Burst Pressure 130.5psi. Maximum Water Temperature 45¸C.
