The 4" PRIMELINE is a large-diameter supply hose built to move high volumes of water from the hydrant or source to the apparatus. A smooth nitrile rubber liner keeps friction loss low over long lays, while polyester reinforcement and a ribbed nitrile cover handle the pressure and abrasion of dragging supply line across real ground. It's rated for use from -54°C up to 100°C and resists ozone, so it holds up through hard Canadian winters and years of storage alike. Finished with 4" Storz aluminum couplings for fast, threadless connections.
