This Unisource 2635 discharge and washdown hose is a lay-flat, medium-duty hose with an extruded, high-tensile nitrile compound tube and cover for durability and maximum bend. It has a one-ply polyester reinforcement to resist expansion and maintaining maximum pressure. It has a Male Pipe Thread (MPT) connector on one end and a Female National Pipe Straight Mechanical (NPSM) swivel connector on the other end. The maximum pressure rating is 150 to 300 pounds per square inch gauge (psig), depending on hose diameter and length, and the operating temperature ranges from -36 to +178 degrees F. This discharge and washdown hose is suitable for use in irrigation, washdown, dewatering, coal preparation and utility plants, petrochemical, oil, and gas drilling, jetting and pump discharge, storage tank cleaning, and sewer cleaning.Industrial hoses transfer or convey air or liquid in hose systems. When selecting industrial hoses, use the STAMPED method to help determine the type of hose needed:S = Size (ID, OD, and length)T = Temperature (maximum and minimum temperatures of material being transported)A = Application (industry or process)M = Material (to be conveyed, type and concentration)P = Pressure (maximum working pressure)E = Ends (type of end connectors or couplings on hose)D = Delivery method (volume and velocity)The inside diameter of the hose must be adequate to keep pressure loss to a minimum and avoid damage to the hose due to heat generation or excessive turbulence. The hose must be capable of withstanding the minimum and maximum temperatures that occur within the hose system. Some applications require specialized oils or chemicals to be conveyed through the system. In this case, hose selection must ensure compatibility of the hose tube, cover, couplings and O-rings with the fluid used. Industrial hoses are used in systems such as air compressors, automatic manufacturing operations, aircraft controls, and tire installation in industries including agriculture, mining, road construction, firefighting, and aviation.Unisource Manufacturing Inc. manufactures hydraulic, pneumatic, and sanitary hoses and hose accessories for automotive, energy, food, cleaning, and other industrial and commercial applications. The company, founded in 1980, is headquartered in Portland, OR.
