The ANDERSON METALS CORP 57487-1208 is a cooler drain fitting designed for use in evaporative cooler and swamp cooler installations. This brass or metal drain fitting connects a 3/4 inch inlet to a 1/2 inch outlet, allowing controlled drainage of standing water from the cooler pan or reservoir. The reducing configuration makes it compatible with common drain line transitions found in residential and light commercial evaporative cooling systems. Plumbers and HVAC technicians typically install this fitting as part of a seasonal drain-down procedure or during routine cooler service. It ships in a package quantity of five units, making it practical for service vehicles and supply stock.
This cooler drain fitting is used in evaporative cooler pans, water distribution systems, and drain assemblies where a 3/4 inch to 1/2 inch reduction is required. It is well suited for residential rooftop swamp cooler installations common in arid and semi-arid climates. Installers use this fitting when connecting the cooler pan drain port to standard household drain lines or hose connections during end-of-season winterization or system maintenance.
Designed as an OEM-style replacement drain fitting for residential and light commercial evaporative cooler systems requiring a 3/4 inch to 1/2 inch drain connection.
Installation is typically performed by a plumber or HVAC technician during cooler service, drain-down, or winterization. Shut off the water supply to the evaporative cooler and allow the pan to drain fully before removing or installing drain fittings. Apply appropriate thread sealant or PTFE tape to threaded connections and verify there are no leaks before returning the system to service. Follow local plumbing codes for drain line routing and material requirements.
