Features:
-
4 inches by 50 feet: The 4-inch by 50-foot specification identifies it as an ultra-high-volume industrial discharge solution. This hose is the "main artery" for 4-inch trash and centrifugal pumps, engineered to move massive quantities of water—up to 600+ gallons per minute—while maintaining the logistical advantage of a collapsible lay-flat design.
-
High quality Lay-Flat hose: The High-Quality Lay-Flat designation refers to its industrial-grade co-extruded construction. This design allows the massive 4-inch hose to collapse into a thin, flexible ribbon when depressurized, combining the extreme volume capacity of a large-bore pipe with the storage convenience and rapid-deployment capability of a lightweight textile.
-
Synthetic fiber reinforcement: The Synthetic Fiber Reinforcement is the high-tensile structural "skeleton" woven into the PVC walls. This reinforcement provides the critical hoop strength required to contain the massive internal pressure of a 4-inch water column—which can weigh over 270 lbs in a single 50-foot section—ensuring the hose maintains its shape without stretching or bursting.
-
NPT couplers: The NPT Couplers are the heavy-duty, threaded connection points that anchor the massive 4-inch line to the pump. In ultra-high-volume systems, these tapered threads are essential; they provide the mechanical "bite" necessary to hold a water column weighing nearly 300 lbs, ensuring a vibration-resistant seal that won't slip or fail under industrial-scale discharge pressures.
-
60 psi: The 60 PSI rating defines its Maximum Working Pressure. In the world of 4-inch industrial pumping, this rating is critical; because a 4-inch hose holds nearly four times the water volume of a 2-inch hose, the "hoop stress" on the walls is immense. This 60 PSI threshold ensures the hose can safely manage massive fluid weights and high-velocity discharge without rupture.
