This Coxreels SL17W-150 left-mount spring rewind hose reel is constructed of powder-coated steel, comes with 50 of 1/4 inside diameter (ID) R-grade welding hose, and is suitable for use in oxy-acetylene welding applications. It has a 1 solid steel axle and lubricated precision bearings for smooth rotation, and side-mount construction for mounting to a flat vertical surface, inside a cabinet, or in an enclosed space. The 50 R-grade hose has a maximum pressure rating of 200 pounds per square inch (psi). The reel (with hose) weighs 38 lb., measures 17 x 18-1/4 x 7-7/8 inches (L x H x W), and has a brass 90-degree dual swivel fitting for connecting both hoses on the same side of the reel. (L is length, the horizontal distance from front to back; H is height, the vertical distance from bottom to top; W is width, the horizontal distance from left to right.) This left-mount spring rewind hose reel is suitable for manufacturing, maintenance, automotive, and other industrial welding applications.Industrial hoses transfer or convey air or liquid in hose systems. When selecting industrial hoses, use the STAMPED method: 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.Coxreels manufactures hoses, cords, cable reels and accessories.
